Description

CLAIM OF PRIORITY

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Dec. 14, 2016 in the Korean Intellectual Property Office and assigned Serial number 10-2016-0170042, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure generally relates to operations of an unmanned aerial vehicle (UAV).

BACKGROUND

In general, UAVs may have various names, such as drone or unmanned aircraft system (UAS). UAVs are aerial vehicles that do not require drivers onboard, and are manufactured to perform specified missions. These UAVs may be wirelessly connected to remote controllers so that they are remotely controlled. A drone may be used for industry and leisure, such as aerial image capture or crop-dusting.

SUMMARY

A controller for a UAV may be an input device that includes a joystick or a touch pad or the like for controlling the UAV. The UAV may move in a constant direction depending on control information received from the input device. Since the UAV is subject to inertial motion, an input prediction range input after a user recognizes the UAV may be often different from the distance in which the UAV actually moves. Further, since the movement speed of the UAV according to an input predicted by the user is often different from the real movement speed of the UAV, it is very difficult for an unskilled user to control the UAV. Thus, it is not easy to operate the UAV accurately. And therefore, when there is a situation where loss of lives or property damage may be caused by the inaccurate operation of the UAV, it is difficult for the user to properly respond to the situation.

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below.

FIG. 1 is a drawing illustrating an example of an unmanned aerial vehicle (UAV) operation environment according to an embodiment of the present disclosure.

Referring to FIG. 1, the UAV operation environment according to an embodiment of the present disclosure may include an electronic device 100 (or a control device) and an aerial vehicle 200 (or a UAV).

According to one embodiment, in the UAV operation environment, a valid range 300 (or a virtual fence or a safe operation valid range) in which the aerial vehicle 200 may drive relative to the electronic device 100 may be set. The aerial vehicle 200 may be operated within the valid range 300. The motion or movement of the electronic device 100 may be used to control the aerial vehicle 200. Thus, the valid range 300 may minimize a situation where loss of life occurs by preventing the UAV from moving to an area the user does not want. Alternatively, although the UAV is moved to an area the user does not intend, he or she may easily change movement of the aerial vehicle 200 or may limit movement of the aerial vehicle 200 by changing the orientation (or position) of the electronic device 100.

According to one embodiment, the aerial vehicle 200 may include at least one propeller. The aerial vehicle 200 may move laterally at a constant altitude above the ground. The aerial vehicle 200 may further include devices such as cameras. The aerial vehicle 200 may capture images in response to control of the electronic device 100 using the camera. The aerial vehicle 200 may transmit the captured images to an external device (e.g., the electronic device 100 or a separately specified server or external electronic device).

According to one embodiment of the present disclosure, the aerial vehicle 200 may be operated within only a constant valid range in response to a location and orientation of the electronic device 100. The aerial vehicle 200 may be operated within a specified angle range with respect to a direction the electronic device 100 faces and a point where the electronic device 100 is located. If an input for departing from the valid range is received by the aerial vehicle 200, the aerial vehicle 200 may maintain a hovering state (e.g., a state where the aerial vehicle 200 floats at a specified height and/or location) at a boundary of the valid range. The aerial vehicle 200 may support a safe operation function and a manual operation function. For example, if the safe operation function is selected, the aerial vehicle 200 may be operated within the specified valid range with respect to the electronic device 100. If the manual operation function is selected, the aerial vehicle 200 may be operated without the limit of the valid range.

The aerial vehicle 200 may receive location information and orientation information of the electronic device 100 from the electronic device 100. The aerial vehicle 200 may calculate a valid range based on the received location and orientation information of the electronic device 100. The aerial vehicle 200 may be operated to be within the calculated valid range.

The electronic device 100 may establish a communication channel of the aerial vehicle 200 and may provide control information to the aerial vehicle 200. The control information may include requests to adjust the movement direction, the altitude, the movement speed, a driving type (e.g., a selfie type of capturing a user who operates the electronic device 100 or a tracking type of tracking and capturing a specified object), or the like of the aerial vehicle 200. The control information may be generated according to a user input received via an input device included in the electronic device 100.

The electronic device 100 may calculate a valid range in which the aerial vehicle 200 will be operated, based on location information and orientation information. The electronic device 100 may provide the calculated valid range information to the aerial vehicle 200. According to an embodiment, if the electronic device 100 controls the aerial vehicle 200 while it is located in a first direction (e.g., a front direction), a valid range (or a flight area) may be set within a radius range (e.g., a field of view (FOV)) set left and right with respect to the first direction. If an axis of the electronic device 100 is moved (or if an orientation is changed) to change an oriented direction during control of the aerial vehicle 200, the electronic device 200 may detect an amount (e.g., an angle) of motion or movement and may set another valid range with respect to a new oriented direction. Thus, the aerial vehicle 200 may be safely operated within an FOV of an operator by operating the aerial vehicle 200 within a newly updated valid range with respect to an oriented direction of the operator who holds the electronic device 100.

The display 150 may output a menu or an icon for selecting any one of a safe operation function or a manual operation function of the aerial vehicle 200. According to an embodiment, the display 150 may output a boundary image, a boundary line, or the like corresponding to a set valid range. The display 150 may output an image captured by a camera located in the electronic device 100. The display 150 may output an image captured by a camera located in the aerial vehicle 200.

The first communication circuit 160 may support a communication function of the electronic device 100. According to an embodiment, the first communication circuit 160 may establish a communication channel with the aerial vehicle 200. The first communication circuit 160 may include a circuit for establishing a short-range communication channel. The first communication circuit 160 may transmit at least one of control information associated with setting a safe operation function or a manual operation function, control information associated with adjusting a movement direction or speed of the aerial vehicle 200, or control information associated with an operation type of the aerial vehicle 200 to the aerial vehicle 200 in response to user control. According to an embodiment of the present disclosure, the first communication circuit 160 may transmit current location information and orientation information of the electronic device 100 to the aerial vehicle 200 or may transmit a valid range calculated based on the current location information and the orientation information of the electronic device 100 to the aerial vehicle 200.

The processor 120 may process or transmit a signal associated with control of the electronic device 100. According to an embodiment, the processor 120 may control to establish a communication channel between the electronic device 100 and the aerial vehicle 200 in response to a user input.

The processor 120 may calculate a valid range based on location information and orientation information of the electronic device 100. The processor 120 may transmit information about the calculated valid range to the aerial vehicle 200. The processor 120 may control the aerial vehicle 200 to be operated within the valid range. In this regard, the processor 120 may include elements shown in FIG. 3.

FIG. 3 is a block diagram illustrating an example of a configuration of a processor according to an embodiment of the present disclosure.

Referring to FIG. 3, a processor 120 according to an embodiment of the present disclosure may include a first sensor information collection module 121 (or a sub-processor), a valid range adjustment module 123, or an aerial vehicle control module 125. At least one of the first sensor information collection module 121, the valid range adjustment module 123, or the aerial vehicle control module 125 may include at least part of the processor 120. Alternatively, at least one of the first sensor information collection module 121, the valid range adjustment module 123, or the aerial vehicle control module 125 may be implemented as an independent processor and may communicate with the processor 120 to perform signaling associated with controlling an aerial vehicle 200 of FIG. 1.

According to one embodiment, the first sensor information collection module 121 may collect location information and orientation information in response to a user input. For example, if a communication channel is established with the aerial vehicle 200 in connection with operating the aerial vehicle 200, the first sensor information collection module 121 may collect current location information and orientation information of an electronic device 100 of FIG. 2. The first sensor information collection module 121 may enable a position sensor (e.g., a GPS) and an acceleration sensor (or a geomagnetic sensor or a gyro sensor). The first sensor information collection module 121 may transmit the collected location and orientation information to the valid range adjustment module 123.

If receiving the location information and the orientation information from the first sensor information collection module 121, the valid range adjustment module 123 may calculate a valid range based on the location information and the orientation information. The valid range adjustment module 123 may determine (or verify) a user setting associated with calculating a valid range. For example, the valid range adjustment module 123 may determine (or verify) whether a specified angle (e.g., 60 degrees, 90 degrees, 120 degrees, or the like from left to right with respect to a front direction) is set with respect to a specific direction of the electronic device 100 (e.g., the front direction in a state where a user holds the electronic device 100). If there is no separate user setting, the valid range adjustment module 123 may use a default setting (e.g., 90 degrees) to calculate a valid range. The valid range adjustment module 123 may determine whether the valid range is to have any number of shapes, such as a cone, a triangular pyramid, a square pole, and the like. If there is no separate setting, the valid range adjustment module 123 may apply a default setting (e.g., the cone) to the calculation of the valid range. The valid range may be configured according to an independent criterion for an upper and lower region or a left and right region based on location information of the electronic device 100. For example, an upper and lower direction may be set to a range for a specified height region, and a left and right direction may be set to a range in the form of a straight line or a curved line according to a set angle.

The valid range adjustment module 123 may determine whether a maximum separation distance between the aerial vehicle 200 and the electronic device 100 is set. According to one embodiment, the valid range adjustment module 123 may determine whether a limit range is set. The limit range may be set, for example, at a distance where communication between the aerial vehicle 200 and the electronic device 100 is disconnected. In another example, the limit range may be set at a distance to prevent collision between the aerial vehicle 200 and some obstruction, such as a building structure, a person, or the ground.

According to one embodiment, the user may input various settings associated with a valid range through a user interface. For example, the valid range adjustment module 123 may output a user interface (e.g., an angle setting screen), associated with at least one of operation for setting an angle, operation for setting a form of a valid range, operation for setting a maximum separation distance, or operation for setting a movement limit range in at least one of upper and lower directions, on a display 150 of FIG. 2. The valid range adjustment module 123 may transmit information about the calculated valid range to the aerial vehicle 200 in real time. The calculating of the valid range may be performed by the aerial vehicle 200. In this case, the valid range adjustment module 123 may be a module operated by an aerial vehicle processor 220 of the aerial vehicle 200.

The aerial vehicle control module 125 may establish a communication channel with the aerial vehicle 200 in response to a user input or according to a set schedule. The aerial vehicle control module 125 may enable a first communication circuit 160 of FIG. 2 in response to a user input and may control the aerial vehicle 200 to start in an initial hovering state (e.g., a fixed state where the aerial vehicle 200 floats up at a constant height from the ground). The aerial vehicle control module 125 may generate control information associated with operating the aerial vehicle 200 in response to a user input and may transmit the generated control information to the aerial vehicle 200. The control information associated with operating the aerial vehicle 200 may include, for example, movement direction information of the aerial vehicle 200, movement speed information of the aerial vehicle 200, operation type information of the aerial vehicle 200, or information about camera control or the like.

FIG. 4 is a block diagram illustrating an example of an aerial vehicle according to an embodiment of the present disclosure.

Referring to FIG. 4, an aerial vehicle 200 according to an embodiment of the present disclosure may include a housing and may include an aerial vehicle processor 220, a second memory 230, a second sensor 240, a second communication circuit 260, and an exercise module 270. Some of these components may be located within the housing, while others are located outside the housing.

According to one embodiment, the second memory 230 may store at least one program or application, data, or the like associated with operating the aerial vehicle 200. According to an embodiment, the second memory 230 may store an aerial application associated with controlling an operation of moving or rotating the aerial vehicle 200 in response to control information received from an electronic device 100 of FIG. 2. The aerial application may include, for example, an instruction set associated with collecting control information provided from the electronic device 100, an instruction set to extract a movement direction, a movement speed, and operation type information from the collected control information, an instruction set to move the aerial vehicle 200 depending on the extracted information, or the like. The aerial application may also include an instruction set to receive valid range information from the electronic device 100 and propose an operation range of the aerial vehicle 200.

The second sensor 240 may collect current location information of the aerial vehicle 200. The second sensor 240 may collect altitude information of the aerial vehicle 200. The second sensor 240 may include a position sensor, an altitude sensor, and the like. The second sensor 240 may transmit the collected location and altitude information to the aerial vehicle processor 220.

The second communication circuit 260 may establish a communication channel with the electronic device 100. According to an embodiment, the second communication circuit 260 may establish a short-range communication channel (e.g., a Bluetooth communication channel) with the electronic device 100. The second communication circuit 260 may receive a pairing request signal from the electronic device 100 and may establish a Bluetooth communication channel through a pairing operation. The second communication circuit 260 may receive location information and orientation information of the electronic device 100 or valid range information from the electronic device 100. The second communication circuit 260 may receive control information associated with operation control from the electronic device 100. The second communication circuit 260 may transmit the received valid range, control information, or the like to the aerial vehicle processor 220.

The exercise module 270 may move the aerial vehicle 200 in response to a direction and speed written in the control information. The exercise module 270 may include a propeller 271, a motor 272, and an operation controller 273. The propeller 271 may include, for example, at least one or more propellers. The motor 272 may be connected with the propeller 271 and may rotate at a specified speed depending on control of the operation controller 273. The operation controller 273 may control the motor 272 and/or the propeller 271 in response to control of the aerial vehicle processor 220 to move the aerial vehicle 200 at a specified speed in a specified direction.

The aerial vehicle processor 220 may process a control signal associated with controlling operation of the aerial vehicle 200 or may transmit and process data. For example, the aerial vehicle processor 220 may transmit an exercise control signal to the exercise module 270 to move the aerial vehicle 200 at a specified speed in a specified direction based on the control information received from the electronic device 100. The aerial vehicle processor 220 according to an embodiment may control the aerial vehicle 200 to be operated within a valid range. The aerial vehicle processor 220 may include elements shown in FIG. 5.

FIG. 5 is a block diagram illustrating an example of a configuration of a processor of an aerial vehicle according to an embodiment of the present disclosure.

Referring to FIG. 5, an aerial vehicle processor 220 according to an embodiment of the present disclosure may include a second sensor information collection module 221, a control information collection module 223, and a driving control module 225. According to an embodiment, at least one of the second sensor information collection module 221, the control information collection module 223, and the driving control module 225 may include at least part of the aerial vehicle processor 220. Alternatively, each of the second sensor information collection module 221, the control information collection module 223, and the driving control module 225 may be implemented as a separate hardware processor and may communicate with the aerial vehicle processor 220.

According to one embodiment, the second sensor information collection module 221 may collect location information of an aerial vehicle 200 of FIG. 4. For example, the second sensor information collection module 221 may enable a GPS module (or device) and may collect current location information of the aerial vehicle 200. The second sensor information collection module 221 may enable an altitude sensor and may collect altitude information of the aerial vehicle 200. The second sensor information collection module 221 may transmit the collected location and altitude information to the driving control module 225.

The second sensor information collection module 221 may provide the collected location and altitude information of the aerial vehicle 200 to an electronic device 100 of FIG. 2 depending on user setting. The location information and the altitude information of the aerial vehicle 200, transmitted to the electronic device 100, may be used to indicate the location or the like of the aerial vehicle 200 within a valid range as visual information or audio information.

The control information collection module 223 may establish a communication channel with the electronic device 100 and may collect control information from the electronic device 100. The control information collection module 223 may extract information associated with operating the aerial vehicle 200 from the collected control information and may transmit the extracted information to the driving control module 225. The control information collection module 223 may receive valid range information from the electronic device 100 and may transmit the received valid range information to the driving control module 225. The control information collection module 223 may receive location information and orientation information of the electronic device 100 from the electronic device 100 and may transmit the location information and the orientation information to the driving control module 225.

The driving control module 225 may receive a function setting associated with operating the aerial vehicle 200. For example, the driving control module 225 may determine a setting value for a safe operation function of the aerial vehicle 200 or a setting value for a manual operation function of the aerial vehicle 200 in information received from the electronic device 100. If the safe operation function is set, the driving control module 225 may determine a valid range. The driving control module 225 may control the aerial vehicle 200 to be moved, based on control information transmitted from the electronic device 100. For example, the driving control module 225 may determine whether a movement location or a movement altitude in which the aerial vehicle 200 is moved departs from the valid range. If the aerial vehicle 200 departs from the valid range, the driving control module 225 may control the aerial vehicle 200 such that the aerial vehicle 200 does not depart from the valid range.

According to one embodiment, if receiving location information and orientation information from the electronic device 100, the driving control module 225 may determine (or verify) a setting value for a valid range (e.g., a setting value for an angle, a setting value for the shape of a valid range, a setting value for a maximum separation distance, a setting value for a movement limit range in at least one of upper and lower directions, etc.), previously stored in a second memory 230 of FIG. 4, and may calculate a valid range based on the verified setting value. The driving control module 225 may provide relative distance information or the like associated with where the aerial vehicle 200 is located in the valid range to the electronic device 100.

FIG. 6 is a signal sequence diagram illustrating an example of a signal flow between devices in a UAV operation environment according to an embodiment of the present disclosure.

Referring to FIG. 6, in connection with operating a UAV, in operation 601, an electronic device 100 may collect its location information. For example, the electronic device 100 may obtain its location information using a GPS or the like. In operation 603, the electronic device 100 may obtain its orientation information. For example, the electronic device 100 may collect a direction angle at which a specific portion of the electronic device 100 is oriented, using an acceleration sensor, a geomagnetic sensor, or the like. According to an embodiment, the electronic device 100 may obtain a direction angle (e.g., a left and right azimuth angle and an upper and lower altitude angle) at which a front side is oriented in a state where a user holds the electronic device 100. According to one embodiment, the electronic device 100 may adjust a valid range in response to motion or movement of a specified size or more. Likewise, the electronic device 100 may disregard motion or movement of a specified size or less so as to not change the valid range. For example, motions related to shakiness of the user's hand may be disregarded.

In operation 605, the electronic device 100 may generate a valid range. For example, the electronic device 100 may determine (or obtain) user setting information and policy information stored in a first memory 130 of FIG. 2 and may generate the valid range based on the collected location information and the collected orientation information and the obtained setting or policy information. The user setting information, the policy information, or the like may include certain angles up and down and left and right with respect to a direction in which a specific point of the electronic device 100 is oriented, a shape of a valid range, or the like.

According to one embodiment, the valid range may be ±30 degrees from left to right relative to a front direction of the electronic device 100. The valid range may be set to 90 degrees from left to right relative to the front direction of the electronic device 100 and may set to a value of 90 degrees or more in response to a user input of a user who wants the aerial vehicle 200 to fly in a wider range. The valid range may vary depending on characteristics of a corresponding location (e.g., there are many obstacles, the location may be indoors, or the like) according to an analysis of location information. In operation 607, the electronic device 100 may provide information about the valid range to the aerial vehicle 200. The electronic device 100 may transmit the valid range information to the aerial vehicle 200 based on a communication channel established between the electronic device 100 and the aerial vehicle 200.

In operation 609, the aerial vehicle 200 may collect location information of the aerial vehicle 200. The collecting of the location information may be performed, for example, after receiving a valid coordinate range from the electronic device 100. If a communication channel is established with the electronic device 100, the aerial vehicle 200 may collect its location information at constant polling intervals or in real time. According to one embodiment, the aerial vehicle 200 may collet altitude information using an altitude sensor.

In operation 611, the aerial vehicle 200 may determine whether its current location is within a valid range. For example, the aerial vehicle 200 may determine whether its location information is included in a valid range set relative to the electronic device 100. The aerial vehicle 200 may determine whether its location information is within the left and right boundaries of the valid range. The aerial vehicle 200 may determine whether its altitude information is within the upper and lower boundaries of the valid range. The aerial vehicle 200 may calculate a distance value from the electronic device 100 and may determine whether its location is within a specified distance from the electronic device 100.

If the location of the aerial vehicle 200 is within the valid range in operation 611, in operation 613, the aerial vehicle 200 may perform normal operation. The electronic device 100 may provide control information according to a use operation to the aerial vehicle 200. The aerial vehicle 200 may exercise movement in response to the received control information. If a location is changed according to control information, the aerial vehicle 200 may collect current location information and may determine whether the collected current location information is within a valid range. If currently moved location information departs from the valid range, the aerial vehicle 200 may operates to return within the valid range.

If the location of the aerial vehicle 200 is not within the valid range in operation 611, in operation 615, the aerial vehicle 200 may perform exception processing. For example, although operation control information according to a user operation is received from the electronic device 100, the aerial vehicle 200 may perform movement within the valid range in a proactive manner. For example, the aerial vehicle 200 may move and stay on a boundary of the valid range from a current location of the aerial vehicle 200. In this operation, the aerial vehicle 200 may collect its location information in real time and may compare its current location with a location within the valid range.

FIG. 7 is a drawing illustrating an example of a valid range according to an embodiment of the present disclosure.

Referring to FIG. 7, as shown, a valid range 200 may be implemented as a quadrangular pyramid shape at a first point of an electronic device 100. For example, the valid range 300 may include a first virtual fence 301 located at a certain angle of an upper side with respect to the first point of the electronic device 100, a second virtual fence 302 located at a certain angle of a lower side with respect to the first point of the electronic device 100, a third virtual fence 303 located at a certain angle of a left side with respect to the first point of the electronic device 100, or a fourth virtual fence 304 located at a certain angle of a right side with respect to the first point of the electronic device 100. To adjust the virtual range, the first virtual fence 301 and the second virtual fence 302 may be adjusted in angle with respect to a specified point of the electronic device 100. Similarly, the third virtual fence 303 and the fourth virtual fence 304 may be adjusted in angle with respect to the specified point of the electronic device 100. The electronic device 100 may provide a user interface for adjusting the left and right angle and the upper and lower angle.

According to one embodiment, the first virtual fence 301 and the second virtual fence 302 may be located to be horizontally symmetric relative to the specified point of the electronic device 100. The third virtual fence 303 and the fourth virtual fence 304 may be located to be vertically symmetric relative to the specified point of the electronic device 100. Alternatively, the first virtual fence 301 and the second virtual fence 302 may be asymmetrical about the specified point of the electronic device 100. For example, an angle between a horizontal surface and the first virtual fence 301 may be set to be greater than an angle between the horizontal surface and the second virtual fence 302 with respect to the horizontal surface at the specified point of the electronic device 100. According to one embodiment, the second virtual fence 302 may be located to form a horizontal angle with the specified point of the electronic device 200. Alternatively, the second virtual fence 302 may include a horizontal surface corresponding to a constant height (e.g., 2 m) from the ground to prevent collisions with persons standing below the aerial vehicle 200. An angle between the third virtual fence 303 and a vertical surface may be set to be the same as an angle between the fourth virtual fence 304. Or the angle may be different.

The electronic device 100 may include a camera. The electronic device 100 may provide the valid range 300 based on images captured by the camera. For example, a quadrangular pyramid range having four sides captured by the camera may be provided as the valid range 300. The electronic device 100 may provide the above-mentioned first to fourth virtual fences 301 to 304 based on a preview image obtained by the camera. The electronic device 100 may provide a screen interface associated with adjusting an angle of each of the first to fourth virtual fences 301 to 304. The user may adjust an angle between each of the first to fourth virtual fences 301 to 304 by adjusting an angle corresponding to each side. The electronic device 100 may provide a preview image and may adjust a portion displayed in response to adjusting an angle to show how wide the valid range 300 where the real aerial vehicle 200 will be moved according to an angle adjusted by the user is.

If an angle associated with the first virtual fence 301 is reduced relative to a horizontal line, the electronic device 100 may downwardly adjust a boundary line of the first virtual fence 301 in response to the reduced angle and may change a display state of the region that is not included in the valid range 300. For example, the electronic device 100 may blur the region outside the valid range 300 or render the region opaque. The electronic device 100 may adjust the size of the valid range 300 in response to a touch event (e.g., pinch zoom) which occurs on the display 150 where a preview image is output. Alternatively, the user may touch and drag an object corresponding to the valid range to adjust the valid range. The aerial vehicle 200 may be limited within a first distance L1 from the electronic device 100. The distance between the aerial vehicle 200 and the electronic device 100 may be changed according to a user setting.

The electronic device 100 may calculate the valid range 300 and may receive location information and altitude information of the aerial vehicle 200 from the aerial vehicle 200. The electronic device 100 may determine whether the aerial vehicle 200 is within the valid range 300 using the calculated valid range 300 and the location information and the altitude information of the aerial vehicle 200. If the aerial vehicle 200 is close to a boundary line of the valid range 300 (e.g., if the aerial vehicle 200 is located within a specified distance from the boundary line), the electronic device 100 may output a specified type of guide information (e.g., a visual or audio notification). If the aerial vehicle 200 enters within a first range with respect to the boundary line of the valid range 300, the electronic device 100 may control the aerial vehicle 200 to reduce a movement speed of the aerial vehicle 200 to a specified speed or less. If the aerial vehicle 200 enters within a second range (e.g., a specified distance nearer to the boundary line than the first range) with respect to the boundary line of the valid range 300, the electronic device 100 may control the aerial vehicle 200 to stop movement of the aerial vehicle 200 so that it hovers within the second range of the boundary line. Operation control according to a distance between the aerial vehicle 200 and the boundary may be performed based on information about the valid range 300 received from the electronic device 100 at the aerial vehicle 200.

FIG. 8 is a drawing illustrating another example of a valid range according to an embodiment of the present disclosure.

Referring to FIG. 8, a valid range 800 of a conical shape may be set relative to a specified point of an electronic device 100. According to an embodiment, the valid range 800 may have a vertical section of which has a triangular shape. This triangular shape may have an upper and lower specified angles with respect to a virtual horizontal surface at the middle of the conical shape. The electronic device 100 may provide a screen interface for adjusting an angle of the triangle corresponding to the vertical section of the conical shape. The electronic device 100 may provide a screen interface for differently adjusting angles of the top and bottom triangles, where the top and bottom triangles are created by bisecting the triangle corresponding to the vertical section using the horizontal surface. A second distance L₂ between the electronic device 100 and an aerial vehicle 200 may be a maximum separation distance between the aerial vehicle 200 and the electronic device 100. The second distance L₂ may be adjusted according to a user input. The second distance L₂ may be adjusted according to an angle of a triangle corresponding to the vertical section of the conical shape. For example, if the angle of the triangle is relatively small, the second distance L₂ may be relatively large. If the angle of the triangle is relatively large, the second distance L₂ may be relatively small.

According to one embodiment, the electronic device 100 may include a camera and may display information about the valid range 800 on the display 150 using the camera. For example, the electronic device 100 may display a preview image captured by the camera on the display 150 and may display the valid range 800, in which the aerial vehicle 200 may be located, as a circle. The valid range 800 displayed as the circle may be adjusted in size in response to a user input (e.g., pinch zoom).

FIG. 9 is a drawing illustrating an example of a change in valid range according to an embodiment of the present disclosure.

Referring to FIG. 9, if one point of an electronic device 100 faces a first direction (e.g., an upper direction relative to the shown drawing) in state 901, a first valid range 300a may be set according to a setting. For example, a constant range of 45 degrees from left to right with respect to the vertical or a constant range corresponding to any angle between 40 degrees and 180 degrees may be set to the first valid range 300a. The electronic device 100 may provide information about the set first valid range 300a to an aerial vehicle 200. The aerial vehicle 200 may be operated within the first valid range 300a.

According to one embodiment, in state 903, the electronic device 100 may change its orientation to a second direction (e.g., a right direction with respect to the shown drawing) according to user operation. If the oriented direction is changed, the electronic device 100 may provide changed control information to the aerial vehicle 200. The aerial vehicle 200 may determine a second valid range 300b based on the control information provided from the electronic device 100 and may move to the second valid range 300b. For example, the aerial vehicle 200 may move to a location in the second valid range 300b, corresponding to a location in the first valid range 300a. For example, if the aerial vehicle 200 is located on a certain region of the center of the first valid range 300a, it may be relocated on the corresponding region of the center of the second valid range 300b. According to another embodiment, when a valid range is changed, the aerial vehicle 200 may move to a region near the boundary between the original valid region and the changed valid region (e.g., the boundary between the first valid range 300a and the second valid range 300b). If the aerial vehicle 200 is set to be disposed apart from a boundary region at a specified distance or more, the aerial vehicle 200 may move from the first valid range 300a to a location disposed apart from a boundary of the second valid range 300b by a specified distance. If a valid range is updated according to a change of direction of the electronic device 100, the aerial vehicle 200 may perform safe operation by moving to the changed valid range.

FIG. 10 is a drawing illustrating another example of a change in valid range according to an embodiment of the present disclosure.

Referring to FIG. 10, in state 1001, an aerial vehicle 200 may be operated within a first valid range 300a with respect to a specified point of an electronic device 100. For example, the aerial vehicle 200 may receive location information and orientation information from the electronic device 100 to calculate the first valid range 300a and may compare the calculated first valid range 300a with its location information. The aerial vehicle 200 may calculate a distance from the electronic device 100 and may adjust its altitude depending on the shape of the first valid range 300a. For example, as described with reference to FIG. 8 or 9, if the first valid range 300a has a shape in which the valid altitude increases as the aerial vehicle 200 moves away from the electronic device 100, the aerial vehicle 200 may move to be located within the valid range depending on the distance from the electronic device 100.

In state 1003, the direction the electronic device 100 used to set the valid range may be rotated by user operation. The first valid range 300a may be changed to a second valid range 300b depending on the rotation of the electronic device 100. The aerial vehicle 200 may compare information about the changed second valid range 300b with its location information to determine whether the aerial vehicle 200 is located within the second valid range 300b. As shown, if the aerial vehicle 200 is located at the boundary of the second valid range 300b, it may maintain its current state (e.g. its current location). If the aerial vehicle 200 is set to be disposed apart from a boundary region of the valid range at a certain distance, it may move to a location disposed apart from the left boundary of the second valid range 300b at the certain distance.

When the second valid range 300b is set, if the aerial vehicle 200 is not located in the second valid range 300b due to a rapid change of direction of the electronic device 100, the aerial vehicle 200 may move the shortest distance available to it so that it can be within the second valid range 300b. As shown, the aerial vehicle 200 may move itself to be located at the left boundary region of the second valid range 300b. And if the user continuously rotates the electronic device 100 in the same direction, the aerial vehicle 200 may move along the moved boundary region. Accordingly, the user may move the aerial vehicle 200 by simply rotating or moving the electronic device 100.

FIG. 11 is a drawing illustrating another example of a change in valid range according to an embodiment of the present disclosure.

Referring to FIG. 11, in state 1101, an aerial vehicle 200 may be operated within a first valid range 300a with respect to an electronic device 100 such that safe operation function is executed. In this state, if the first valid range 300a is changed to a second valid range 300b as a user changes the oriented direction of the electronic device 100, the aerial vehicle 200 may move within the second valid range 300b. The aerial vehicle 200 may maintain a relative location in the first valid range 300a in the second valid range 300b. For example, if the aerial vehicle 200 is located in a central portion in the first valid range 300a, it may automatically move to a central portion of the second valid range 300b. According to one embodiment, if the aerial vehicle 200 is not included in the second valid range 300b due to rapid change of the first valid range 300a, it may move within the second valid range 300b. But if the electronic device 100 changes direction gradually, the aerial vehicle 200 may move along a boundary region of a valid range.

FIG. 12 is a drawing illustrating an example of operation of a valid range of an electronic device connected with a camera according to an embodiment of the present disclosure.

Referring to FIG. 12, a wearable device 400 according to one embodiment of the present disclosure may be worn by the user. The wearable device 400 may include a camera 480. The wearable device 400 may provide an augmented reality (AR) environment 401 using images captured using the camera. The AR environment 401 may include, for example, an environment in which the wearable device 400 analyzes images captured by the camera 480 and displays virtual objects 307 according to the analyzed result on the wearable display 450. Thus, while wearing the wearable device 400, the user may see both the real aerial vehicle 200 and the virtual objects 307 via the wearable display 450 having specified transparency.

In the above-mentioned environment, the wearable display 450 may display a virtual fence object 309 corresponding to a valid range 300 based on an image capture environment in which the camera 480 captures images. In the shown drawing, the virtual fence object 309 may be an object including 4 edges. The aerial vehicle 200 may be operated within the virtual fence object 309 corresponding to the valid range 300.

According to an embodiment, the wearable device 400 may further include a wearable input device 410 associated with adjusting a distance. The user may operate the wearable input device 410 to adjust a separation distance between the wearable device 400 and the aerial device 200. The wearable input device 410 may be worn close to the eyes of the user and may adjust the valid range 300 in response to a direction the user faces. The aerial vehicle 200 may move according to a change in the valid range 300 so that it is located within the changed valid range. The user may adjust a direction his or her head faces to adjust his or her view (e.g., the direction in which the wearable device 400 is oriented) as well as to adjust the movement direction and speed of the aerial vehicle 200 (e.g., by changing the valid range so that the aerial vehicle 200 moves to be within the valid range). The wearable device 400 may include, for example, an eyeglasses-type electronic device, a head mounted display (HMD), or the like.

According to an embodiment, the camera 480 included in the wearable device 400 may electrically or electronically provide an image capture screen of a similar showing the range that the user sees on the wearable display 450. The wearable device 400 may identify the aerial vehicle 200 captured by the camera 480. The wearable device 400 may generate control information for controlling the current location of the aerial vehicle 200 identified by the camera 480 within a field of view (FOV) or an image capture range of the camera 480 and may provide the generated control information to the aerial vehicle 200. According to one embodiment, if the wearable device 400 enters within a certain distance from an FOV boundary or arrives at the FOV boundary through an image analysis of the camera 480, the wearable device 400 may output a control user interface (UI) for moving the aerial vehicle 200 within the valid range 300 on the wearable display 450 or may output a notification as a specified type of guide information (e.g., at least one of a screen, an audio, or haptic feedback).

FIG. 13 is a flowchart illustrating an example of a signal flow between devices in connection with operation of a valid range of a camera-based aerial vehicle according to an embodiment of the present disclosure.

Referring to FIG. 13, in operation 1301, an electronic device 100 including a camera may perform a pairing operation with an aerial vehicle 200. For example, the electronic device 100 and the aerial vehicle 200 may include a wireless communication circuit (e.g., a short-range communication circuit, a Bluetooth communication circuit, or the like) associated with performing the pairing operation. Any one of the electronic device 100 and the aerial vehicle 200 may have a waiting state depending on user input or schedule information, and the other device may perform a pairing operation in response to a user input. After completing the pairing operation, the electronic device 100 may execute a safe operation function for setting an FOV of the camera to a valid range.

In operation 1303, the electronic device 100 may recognize the aerial vehicle 200. The electronic device 100 may capture a specified direction using the camera and may obtain a preview image for the specified direction. The electronic device 100 may analyze the obtained image to determine whether an object corresponding to the aerial vehicle 200 is detected. The electronic device 100 may store image information associated with the aerial vehicle 200 in a first memory 130 of FIG. 2. Alternatively, the electronic device 100 may receive location information and altitude information of the aerial vehicle 200 and may identify the aerial vehicle 200 in the obtained image using the received location and altitude information. In this alternative embodiment, even when there is a plurality of aerial vehicles in the capture image, the electronic device 100 may detect its paired aerial vehicle.

In operation 1305, if the aerial vehicle 200 is recognized, the electronic device 100 may perform a tracking operation. In operation 1307, the electronic device 100 may determine whether the aerial vehicle 200 is within an FOV. For example, the electronic device 100 may determine whether the aerial vehicle 200 is included in the images captured by the camera, through the analysis of the obtained images. If the aerial vehicle 200 is within the FOV, the electronic device 100 may transmit first control information to the aerial vehicle 200. If the aerial vehicle is not included in the FOV, the electronic device 100 may transmit second control information to the aerial vehicle 200.

After performing the pairing operation with the electronic device 100 in operation 1301, the aerial vehicle 200 may be operated according to reception of control information. For example, in operation 1309, the aerial vehicle 200 may receive first or second control information from the electronic device 100. In this case, in operation 1311, the aerial vehicle 200 may perform normal flight depending on control information (e.g., the first control information). The normal flight may include operation in which the aerial vehicle 200 moves at a specified speed in a specified direction, the specified speed and the specified direction being input by the user. Alternatively, in operation 1309, the aerial vehicle 200 may receive the second control information from the electronic device 100. In this case, in operation 1311, the aerial vehicle 200 may perform exception processing depending on control information (e.g., the second control information). The exception processing may include, for example, moving the aerial vehicle to be within an FOV of the camera irrespective of a specified direction and a specified speed input by the user. For example, if the aerial vehicle 200 is located in a right boundary of the FOV, it may maintain its current state even if the user input specifies movement further to the right. The electronic device 100 may inform the user that it is impossible to perform right movement of the aerial vehicle 200 or may output information for requesting to execute a manual operation function for the right movement.

FIG. 14 is a signal sequence diagram illustrating an example of a signal flow between devices in connection with operation of a valid range based on a camera according to an embodiment of the present disclosure.

Referring to FIG. 14, a system associated with operating a valid range based on a camera may include, for example, a boundary setting device (e.g., a wearable electronic device), an electronic device 100 (e.g., an aerial vehicle controller), or an aerial vehicle 200.

In operation 1401, the boundary setting device 500 and the electronic device 100 may perform a pairing operation to establish a communication channel. The electronic device may also perform a pairing operation with the aerial vehicle 200 to establish a communication channel.

In operation 1403, the boundary setting device 500 may enable a camera in response to a user input and may analyze images (e.g., a preview image or the like) obtained by the enabled camera. The boundary setting device 500 may determine whether the aerial vehicle 200 is present in the images based on the analysis of the images. The boundary setting device 500 may previously store an image associated with the aerial vehicle 200 (or a feature points extracted from the image or a model generated based on the feature points) to recognize the aerial vehicle 200 and may compare information extracted through an analysis of the stored image with information extracted through an analysis of the currently obtained image. The boundary setting device 500 may set the FOV of the camera as the valid range.

If the aerial vehicle 200 is detected, in operation 1405, the boundary setting device 500 may track the aerial vehicle 200. For example, the boundary setting device 500 may track motion or movement of the aerial vehicle 200 in response to control by the electronic device 100.

In operation 1407, the boundary setting device 500 may determine whether motion or movement information of the aerial vehicle 200 departs from an FOV boundary. If the aerial vehicle 200 departs from the FOV boundary of the camera, in operation 1409, the boundary setting device 500 may transmit an exception processing request to the electronic device 100. The boundary setting device 500 may provide information about the valid range and location information of the aerial vehicle 200 to the electronic device 100.

If receiving the exception processing request from the boundary setting device 500 in operation 1409, in operation 1411, the electronic device 100 may output a notification for the reception of the exception processing request. According to an embodiment, the electronic device 100 may output visual information associated with the reception of the exception processing request on a display 150 of FIG. 2 or may provide auditory feedback to inform the user of the reception of the exception processing request. The electronic device 100 may also output haptic feedback of a specified pattern according to occurrence of the exception processing request.

In operation 1413, the electronic device 100 may transmit a change control signal associated with exception processing to the aerial vehicle 200. The change control signal may include, for example, driving control information for moving the aerial vehicle 200 within the FOV If receiving the change control signal from the electronic device 100, in operation 1415, the aerial vehicle 200 may perform an operation for moving the aerial vehicle 200 within the FOV The aerial vehicle 200 may control movement from a current location to the closest point in an FOV region.

If the aerial vehicle 200 does not depart from the FOV boundary in operation 1407, in operation 1417, the boundary setting device 500 may transmit normal control information to the electronic device 100. If receiving the normal control information from the boundary setting device 500, in operation 1419, the electronic device 100 may receive a user input. The user input may include, for example, an input for moving the aerial vehicle 200 in a certain direction. In operation 1421, the electronic device 100 may generate driving control information according to the user input and may transmit the generated driving control information to the aerial vehicle 200. In operation 1423, the aerial vehicle 200 may perform flight depending on the received driving control information. For example, the aerial vehicle 200 may operate its motor to move itself in the certain direction specified by the user.

If the user wears an eyeglasses electronic device (e.g., the boundary setting device 500) including a camera or the like and operates a controller (e.g., the electronic device 100) for controlling the aerial vehicle 200, a valid range operation system according to an embodiment of the present disclosure may ensure safe operations of the aerial vehicle 200 by limiting a motion or movement range of the aerial vehicle 200 using the eyeglasses electronic device while operating the aerial vehicle 200.

FIG. 15 is a drawing illustrating an example of a screen interface associated with operation of a valid range according to an embodiment of the present disclosure.

Referring to FIG. 15, an electronic device 100 may include a display 150 and may display an aerial vehicle 200 on the display 150. The aerial vehicle 200 may move in the valid range 300 and, as shown, may move to an area adjacent to a right boundary of the valid range 300. In this case, as shown, the display 150 may display a boundary line object 151 corresponding to the right boundary line of the valid range 300. The display 150 may display a virtual aerial vehicle 1501 corresponding to the aerial vehicle 200 on the display 150.

If the virtual aerial vehicle 1501 is approached to the boundary line object 151 (e.g., a right boundary line object) within a specified distance, the electronic device 100 according to an embodiment of the present disclosure may output a control UI 153 so that the user can control the aerial vehicle 200 to stay within the valid range 300. The control UI 153 may include a control object (e.g., left, right, up, down, rotation, or the like) for each direction. The control object in the control UI 153 that may be used to control the aerial vehicle 200 to stay within the valid range 300 may be displayed to be different from the other control objects. For example, as shown in the figure, the left control object, which can be used to control the aerial vehicle 200 to move away from the boundary line object 151, may be highlighted.

If receiving a user input signal according to an operation of the control UI 153, the electronic device 100 may determine whether the received user input is an input for moving the aerial vehicle 200 away from a boundary line. If so, the electronic device 100 may transmit the control information to the aerial vehicle 200. On the other hand, if receiving an input for moving close to the boundary line object 151 or crossing the boundary line object 151, the electronic device 100 may inform a user of invalidity of the input and may output guide information for requesting a specified direction instead (e.g., left movement of the aerial vehicle 200).

According to an embodiment, an image output on the display 150 may be an image obtained by a camera included in the electronic device 100 or an image captured by a camera of a wearable electronic device worn by the user. If an image capture angle of the camera is changed according to motion or movement of the wearable electronic device, the display 150 may output an image collected at the changed image capture angle of the camera. If the aerial vehicle 200 moves in a direction to cross a boundary line of the valid range 300 or if the aerial vehicle 200 departs from an FOV of the camera, the electronic device 100 may automatically control the aerial vehicle 200 to move the aerial vehicle 200 to stay within a specified distance of the crossed boundary line. For example, the aerial vehicle 200 may depart from the valid range 300 irrespective of intention of the user due to environmental factors, such as wind or inertial motion. In this case, if the aerial vehicle 200 crosses a boundary line of the valid range 300, the electronic device 100 may generate control information for moving the aerial vehicle 200 to be within a specified distance of the boundary line and may provide the generated control information to the aerial vehicle 200. The aerial vehicle 200 may accordingly move to be within the specified distance of the boundary line of the valid range 300.

The display 150 may display the virtual aerial vehicle 1501 corresponding to the aerial vehicle 200 and a range object corresponding to a boundary of the valid range 300. If the user touches and drags the virtual aerial vehicle 1501 to perform an operation of moving the virtual aerial vehicle 1501 within the range object, the electronic device 100 may automatically generate control information corresponding to the touch operation and may provide the control information to the aerial vehicle 200.

The electronic device 100 may obtain FOVs of a plurality of cameras and location information of the plurality of cameras and may output a selection UI for selecting a camera. The user may select a specified camera on the selected UI, and the electronic device 100 may provide the obtained information to the aerial vehicle 200.

FIG. 16 is a flowchart illustrating an example of an operation method of an electronic device associated with operating a UAV according to an embodiment of the present disclosure.

Referring to FIG. 16, in connection with operating the UAV, in operation 1601, an electronic device 100 of FIG. 1 may be connected with an aerial vehicle 200 of FIG. 1. For example, the electronic device 100 may perform a pairing operation with the aerial vehicle 200 in response to a user input.

In operation 1603, if an event is generated, the electronic device 100 may determine whether the generated event is an event associated with a safe operation function. For example, the electronic device 100 may determine whether there is a setting associated with the safe operation function or whether there is a user input for requesting to execute the safe operation function. If the generated event is not the safe operation function, in operation 1605, the electronic device 100 may control operation according to manual function. For example, if a manual operation function is set, the electronic device 100 may generate control information according to a user input and may provide the generated control information to the aerial vehicle 200. The aerial vehicle 200 may fly according to the control information.

In operation 1607, the electronic device 100 may collect its location and orientation information and may collect location information of the aerial vehicle 200. The electronic device 100 may enable a position sensor, an acceleration sensor, and the like and may collect the location information and the orientation information. The electronic device 100 may request the aerial vehicle 200 to transmit the location information of the aerial vehicle 200. The electronic device 100 may collect altitude information of the aerial vehicle 200. According to one embodiment, collection of at least one of location information and altitude information of the aerial vehicle 200 may be performed after operation 1609.

In operation 1609, the electronic device 100 may calculate a valid range according to one or more settings. For example, the electronic device 100 may determine (or obtain information of) an angle range, an area range, a space range, or the like for a specified direction with respect to the electronic device 100. The setting may include, for example, an angle value for a certain direction with respect to a certain point of the electronic device 100. The setting may include, for example, a shape of the valid range. The setting may include, for example, a maximum separation distance between the aerial vehicle 200 and the electronic device 100.

In operation 1611, the electronic device 100 may determine whether the aerial vehicle 200 is within the valid range. In this regard, the electronic device 100 may determine whether the location information of the aerial vehicle 200 is within the valid range. If the valid range includes a valid altitude, the electronic device 100 may determine whether an altitude of the aerial vehicle 200 is within the valid altitude. For example, the valid altitude threshold may be lower when the aerial vehicle 200 is closer to the electronic device 100 and may be higher when the aerial vehicle 200 is farther away from the electronic device 100. According to another embodiment, the valid altitude may be set to be identical (e.g., a height of 2 m or more) irrespective of the separation distance from the electronic device 100.

If the aerial vehicle 200 is within the valid range, in operation 1613, the electronic device 100 may transmit first control information to the aerial vehicle 200. The first control information may include, for example, direction, distance, or speed information for moving the aerial vehicle 200 depending on a user input. If the aerial vehicle 200 is out of the valid range, in operation 1615, the electronic device 100 may transmit second control information to the aerial vehicle 200. The second control information may include, for example, information such as a movement direction, distance, or speed for stopping the aerial vehicle 200 or moving the aerial vehicle 200 to a specified point of a valid range (e.g., a boundary line of the valid range).

In operation 1617, the electronic device 100 may determine whether an event associated with ending the safe operation function or ending an operation function of the aerial vehicle 200 occurs. If the event associated with ending the function does not occur, the electronic device 100 may branch to operation 1603 to perform the operations again from operation 1603. When the event associated with ending the safe operation function occurs, the electronic device 100 may branch to operation 1605 to control operation of the aerial vehicle 200 according to the manual function. According to various embodiments, If the event associated with ending the operation function of the aerial vehicle 200 occurs, the electronic device 100 may transmit a control signal to the aerial vehicle 200, the control signal includes movement direction, distance, and coordinate information to return the aerial vehicle 200 to a specified point (e.g., a point where the aerial vehicle 200 is initially started)

In the above description, an embodiment is exemplified as the electronic device 100 verifies operation within a valid range of the aerial vehicle 200 and performs operations associated with controlling the aerial vehicle 200. But the present disclosure is not so limited. For example, the electronic device 100 may collect only its location and orientation information in connection with calculating the valid range and may provide the collected information to the aerial vehicle 200. If location information and orientation information of the electronic device 100 are changed, the electronic device 100 may transmit the changed location information and orientation information to the aerial vehicle 200 to update the valid range. The electronic device 100 may calculate a valid range and may provide information about the calculated valid range to the aerial vehicle 200. If at least one of location information and orientation information of the electronic device 100 is changed, the electronic device 100 may calculate a changed valid range again and may provide information about the changed valid range to the aerial vehicle 200.

FIG. 17 is a flowchart illustrating an example of an operation method of an aerial vehicle associated with operating a UAV according to an embodiment of the present disclosure.

Referring to FIG. 17, in connection with operating the UAV, in operation 1701, an aerial vehicle 200 of FIG. 1 may be connected with an electronic device 100 of FIG. 1. For example, the aerial vehicle 200 may be in a connection waiting state and may be paired with the electronic device 100 in response to a pairing connection request from the electronic device 100. In operation 1703, the aerial vehicle 200 may determine whether there is a safe operation function setting or whether there is a user input for requesting to execute a safe operation function. If there is no the safe operation function setting or the user input, in operation 1705, the aerial vehicle 200 may control operation according to its manual function or manual mode. For example, the aerial vehicle 200 may move at a specified direction, distance, or speed based on control information received from the electronic device 100 in its default manual mode.

If there is the setting associated with the safe operation function or if the user input occurs in operation 1703, in operation 1707, the aerial vehicle 200 may collect valid range information and location information. According to an embodiment, the aerial vehicle 200 may receive the valid range information from the electronic device 100. Alternatively, the aerial vehicle 200 may receive location information and orientation information of the electronic device 100 and a setting value associated with a valid range from the electronic device 100. The aerial vehicle 200 may then calculate a valid range based on the received location and orientation information of the electronic device 100 and/or the setting value associated with the valid range. The aerial vehicle 200 may also collect its own location and altitude information using the appropriate location and altitude sensors.

In operation 1709, the aerial vehicle 200 may determine whether its current location is within the valid range. If the aerial vehicle 200 is within the valid range, in operation 1711, the aerial vehicle 200 may perform normal operation. For example, the aerial vehicle 200 may move in an input direction by an input distance or may move at an input speed, in response to a user input included in control information transmitted from the electronic device 100.

If the aerial vehicle 200 is out of the valid range in operation 1709, in operation 1713, the aerial vehicle 200 may perform exception processing. For example, the aerial vehicle 200 may automatically move to a specified point in the valid range (e.g., a boundary line of the valid range). While performing this operation, the aerial vehicle 200 may determine whether control information received from the electronic device 100 will result in the aerial vehicle 200 being placed outside the valid range. If so, the aerial vehicle 200 may disregard the control information.

In operation 1715, the aerial vehicle 200 may determine whether an event associated with ending a safe operation function is received. Upon ending the safe operation function, the aerial vehicle 200 may end operation in the valid range. The aerial vehicle 200 may branch to operation 1705 and execute the manual operation function after safe operation function is ended and may perform an operation according to a user input of the electronic device 100. If the event associated with ending the safe operation function is not received, the aerial vehicle 200 may branch to operation 1703 to perform the operations again from operation 1703.

FIG. 21 illustrates a program module of an unmanned aerial vehicle according to an embodiment of the present disclosure.

Referring to FIG. 21, an unmanned aerial vehicle 4001 may include an application platform or a flight platform. The unmanned aerial vehicle 4001 may include at least one application platform for operating the unmanned aerial vehicle 4001 and providing a service by receiving a control signal through a wireless link and at least one flight platform for controlling flight depending on a navigation algorithm.

The application platform according to an embodiment of the present disclosure may perform communication control (connectivity), image control, sensor control, and charging control on elements of the unmanned aerial vehicle 4001 and may perform an operation change according to a user application. The application platform may be executed in a processor. The flight platform may execute flight, posture control, or a navigation algorithm of the unmanned aerial vehicle 4001. The flight platform may be executed in the processor or a movement control module. The application platform may send a control signal to the flight platform while performing the communication, image, sensor, and charging controls.

According to one embodiment, the processor may obtain an image of a subject taken through a camera module. The processor may analyze the obtained image to generate a command to pilot the unmanned aerial vehicle 4001. For example, the processor may generate information about the size and moving state of the subject, a relative distance between a photographing device and the subject, altitude information, and azimuth angle information. The processor may generate a tracking flight control signal of the unmanned aerial vehicle 4001 by using the computed information. The flight platform may pilot the unmanned aerial vehicle 4001 (may control the posture and movement of the unmanned aerial vehicle 4001) by controlling the movement control module based on the received control signal.

The position, flight posture, angular velocity, and acceleration of the unmanned aerial vehicle 4001 may be measured through a GPS module and a sensor module. Output information of the GPS module and the sensor module may be generated and may be basic information of a control signal for navigation/automatic control of the unmanned aerial vehicle 4001. Information of a barometric pressure sensor capable of measuring altitude through an atmospheric pressure difference according to flight of an unmanned photographing device and information of ultrasonic sensors capable of performing accurate altitude measurement at a low altitude may also be used as basic information. In addition, a control data signal received from a remote controller, battery state information of the unmanned aerial vehicle 4001, and the like may also be used as basic information of a control signal.

The unmanned aerial vehicle 4001 according to an embodiment of the present disclosure may fly using a plurality of propellers. The propellers may change a rotational force of a motor to a propulsive force. The unmanned aerial vehicle 4001 may be referred to as a quad-copter, a hexa-copter, or an octo-copter according to the number of rotors (propellers), in which the quad-copter has four rotors (propellers), the hexa-copter has six rotors (propellers), and the octo-copter has eight rotors (propellers).

The unmanned aerial vehicle 4001 according to an embodiment of the present disclosure may control the propellers based on a received control signal. The unmanned aerial vehicle 4001 may fly by two principles: lift and torque. The unmanned aerial vehicle 4001 may rotate one half the multiple propellers in the clockwise (CW) direction and the other half in the counter clockwise (CCW) direction for rotation. The three-dimensional coordinates of a drone according to flight may be determined by pitch (Y)/roll (X)/yaw (Z). The unmanned aerial vehicle 4001 may tilt forwards, backwards, leftwards, or rightwards to fly. If the unmanned aerial vehicle 4001 tilts, the direction of air flow generated by the propellers (rotors) may be changed. For example, if the unmanned aerial vehicle 4001 tilts forwards, air may flow slightly backwards, as well as upwards and downwards. Accordingly, the unmanned aerial vehicle 4001 may move forwards by the air layer pushed backwards according to the law of action and reaction. The unmanned aerial vehicle 4001 may be tilted in a direction by decreasing the speed of motors on the front side thereof and increasing the speed of motors on the rear side thereof in the corresponding direction. Since this method is common to all directions, the unmanned aerial vehicle 4001 may be tilted and moved by only adjusting the speed of the motor module (rotors).

In the unmanned aerial vehicle 4001 according to an embodiment of the present disclosure, the flight platform may receive a control signal generated by the application platform to control the motor module, thereby controlling the pitch (Y)/roll (X)/yaw (Z) of the unmanned aerial vehicle 4001 and performing flight control according to a moving path.
