Exemplary embodiments will be described with reference to the accompanying drawings. In the case where there is no conflict between the exemplary embodiments, the features of the following embodiments and examples may be combined with each other.

As shown in FIG. 1, an embodiment of the present disclosure provides a handheld gimbal 100, which includes a handle part 101, a first bracket 102, a second bracket 103, a third bracket 104, a first motor 105, a second motor 106, and a third motor 107.

Different use modes may correspond to different attitude, which is convenient for users to switch the handheld gimbal to a suitable use mode in a variety of use cases, which can improve the convenience of operation while ensuring the stability and clarity of the captured images.

In some embodiments, the first bracket 102 may be used to mount a payload, the second bracket 103 may be connected between the first bracket 102 and the third bracket 104, and the third bracket 104 may be used to connected with the handle part 101. The first motor 105 may be installed on the first bracket 102 and used to connect the first bracket 102 and the second bracket 103. The first motor 105 may drive the first bracket 102 to rotate to realize the switch between the plurality of use modes of the handheld gimbal 100.

The handheld gimbal may be switched between a plurality of use modes, which is convenient for users to use appropriate use modes based on different use cases, which not only improves the convenience of operation, but also ensures the stability and clarity of the captured images.

In some embodiments, when the handle part 101 is substantially in a vertical state, tilting the handle part 101 counterclockwise or clockwise to rotate the handle part 101 around the roll axis may cause the first motor 105 to follow the handle part 101 to rotate to drive the first bracket 102 to rotate around the roll axis; and/or, when the handle part 101 is substantially in a horizontal state, tilting the handle part 101 counterclockwise or clockwise to rotate the handle part 101 around the yaw axis may cause the first motor 105 to follow the handle part 101 to rotate to drive the first bracket 102 to rotate around the yaw axis. Tilting the handle part 101 counterclockwise can be referred to rotating the handle counterclockwise in a direction perpendicular to the axis of the handle. The direction may be substantially parallel to the direction of the first bracket, and the way to tilt the handle part 101 counterclockwise may be to tilt the handle to the left. Tilting the handle part 101 clockwise can be referred to rotating the handle counterclockwise around the direction perpendicular to the axis of the handle.

The second direction may be substantially perpendicular to the current axis direction of the handle part 101. When the handheld gimbal 100 is switched from the tenth use mode as shown in FIG. 11 to the fourteenth use mode, the first bracket 102 may rotate 90° around the pitch axis, the screen orientation of the mounted shooting device may change to face the sky, and the shooting device may be in the portrait state.

In one embodiment, when the handheld gimbal 100 is in the fifteenth use mode, the handle part 101 may be substantially in the second side-lying state, and the back of the first bracket 102 may face the third direction. The third direction may be substantially perpendicular to the current axis direction of the handle part 101, and the second direction may be substantially opposite to the third direction.

The fourth direction may be substantially perpendicular to the current axis direction of the handle part 101, and the fourth direction may be substantially opposite to the first direction. When the handheld gimbal 100 is switched from the tenth use mode as shown in FIG. 11 to the sixteenth use mode, the first bracket 102 may rotate 180° around the pitch axis, the orientation of the back of the mounted shooting device may be substantially opposite to the orientation of the back of the shooting device as shown in FIG. 11, and the shooting device may be in the portrait state.

It should be noted that the preset angle range described above can be set based on actual conditions, which is not limited in the present disclosure. In some embodiments, the preset angle range may be between 30° to 150°.

In one embodiment, the handheld gimbal 100 may also include a controller. The controller may be configured to control the rotation of the first motor 105, the second motor 106, and/or the third motor 107 to change the attitude of the handle part 101, the attitude of the first bracket 102, and/or the joint angles of the motors of the handheld gimbal 100, thereby realizing the switch of the handheld gimbal between different use modes.

Referring to FIG. 15, which is a flowchart of switching the use mode of the handheld gimbal according to an embodiment of the present disclosure. As shown in FIG. 15, the controller is used to implement step S101 to step S103.

Step S101, obtaining a mode switching condition that needs to be met to perform mode switching based on a detected mode switching operation and a current use mode of the handheld gimbal.

More specifically, the controller may be configured to obtain the current attitude and the historical attitude of the handle part 101, where the current attitude may be the attitude of the handle part 101 at the current time, and the historical attitude may be the attitude of the handle part 101 at a previous time. The controller may also be configured to obtain the current orientation and the historical orientation of the back of the first bracket 102, where the current orientation may be orientation of the back of the first bracket 102 at the current time, and the historical orientation may be the orientation of the back of the first bracket 102 at the previous time. The controller may also be configured to obtain the current joint angle and historical joint angle of each motor of the handheld gimbal 100, where the current joint angle may be the joint angle of each motor of the handheld gimbal 100 at the current time, and the historical joint angle may be the joint angle of each motor of the handheld gimbal 100 at the previous time. The controller may also be configured to determine whether the user is performing the mode switching operation on the handheld gimbal 100 based on the current attitude and historical attitude of the handle part 101, and/or the current orientation and historical orientation of the back of the first bracket 102, and/or the current joint angle and historical joint angle of each motor.

The controller may be configured to determine the attitude change trend of the handle part 101 based on the current attitude and the historical attitude of the handle part 101, determine the change trend of the back of the first bracket 102 based on the current orientation and the historical orientation of the back of the first bracket 102, determine the change trend of the joint angle of each motor based on the current joint angle and the historical joint angle of each motor of the handheld gimbal 100, and determine whether the user is performing the mode switching operation on the handheld gimbal 100 based on the attitude change trend, the orientation change trend, and/or the joint angle change trend. Through the attitude change trend of the handle part 101, the orientation change trend of the back of the first bracket 102, and/or the joint angle change trend of each motor, the user's mode switching operation of the handheld gimbal 100 can be accurately detected, which is convenient for the subsequent accurate control of the handheld gimbal for mode switching.

It should be noted that when the attitude change trend meets a preset attitude change condition, the orientation change trend meets a preset orientation change condition, and/or the joint angle change trend meets a preset joint angle change condition, it can be determined that the user has performed a mode switching operation on the handheld gimbal 100. In addition, when the attitude change trend does not meet the preset attitude change condition, the orientation change trend does not meet the preset orientation change condition, and the joint angle change trend does not meet the preset joint angle change condition, it can be determined that the user has not performed a mode switching operation on the handheld gimbal 100.

In one embodiment, before the user switches the mode of the handheld gimbal 100, the controller may control the handheld gimbal 100 to be in a mode switching state. In some embodiments, the attitude of the handheld gimbal 100 in the mode switching state may not change automatically, but it can be changed under the user's operation, and the attitude of the first bracket 102 may not change with the attitude of the handle part 101. After the handheld gimbal 100 completes the mode switching, the handheld gimbal 100 can be controlled to be in a normal follow state. In some embodiments, the attitude of the first bracket 102 of the handheld gimbal 100 in the normal follow state may change with the attitude of the handle part 101. In this way, problems such as damage to the gimbal and the inability to switch the use mode due to the automatic change of the attitude of the handheld gimbal 100 can be prevented when the use mode of the handheld gimbal 100 is switched, which greatly improves the safety and reliability of mode switching.

In one embodiment, the mode switching condition acquisition method may include the controller obtaining the use mode and the mode switching operation, and a mapping relationship table between the mode switching conditions, where the use mode and the mode switching operation has a corresponding relationship with the mode switching conditions; and, obtaining the mode switching conditions that need to be met to perform the mode switching based on the mode switching operations, the current use mode of the handheld gimbal 100, and the mapping relationship table. That is, the mapping relationship table can be queried to obtain the mode switching condition corresponding to the mode switching operations and the current use mode of the handheld gimbal 100. It should be noted that the mapping relationship table between the use modes and the mode switching operations and the mode switching conditions described above can be set based on actual conditions, which is not limited in the embodiments of the present disclosure. By setting the mapping relationship table, the mode switching condition that needs to be met to perform mode switching can be quickly and accurately obtained, which is convenient for the subsequent control of the handheld gimbal 100 for mode switching.

Step S102, determining whether the handheld gimbal meets the mode switching condition.

More specifically, the controller may be configured to obtain current attitude information of the handle part 101, current attitude information of the first bracket 102, and/or the current joint angles of the motors of the handheld gimbal 100, where the current attitude information of the handle part may be the attitude information of the handle part at the current time, the current attitude information of the first bracket 102 may be the attitude information of the first bracket 102 at the current time, and the current joint angle of each motor may be the joint angle of each motor at the current time; and, determine whether handheld gimbal meets the mode switching condition based on the current attitude information of the handle part 101, the current attitude information of the first bracket 102, and/or the current joint angles of the motors of the handheld gimbal 100. Through the current attitude information of the handle part 101, the current attitude information of the first bracket 102, and/or the current joint angles of the motors of the handheld gimbal 100, whether the handheld gimbal 100 meets the mode switching condition can be accurately determined, which is convenient for the accurate subsequent controls of the handheld gimbal 100 in performing mode switching.

It should be noted that the mode switching condition may include at least one of the handle part 101, the first bracket 102, and each motor of the handheld gimbal 100 meeting a first attitude condition, a second attitude condition, and a joint angle condition, respectively. Then the method for determining whether the handheld gimbal 100 meets the mode switching condition may include obtaining the first attitude condition, the second attitude condition and the joint angle condition that the handle part 101, the first bracket 102, and each motor of the handheld gimbal 100 needs to meet from the mode switching condition; determining whether the current attitude of the handle part 101 meets the first attitude condition based on the current attitude information of the handle part 101; and/or determining whether the current attitude of the first bracket 102 meets the second attitude condition based on the current attitude information of the first bracket 102; and/or determining whether the current joint angle of each motor of the handheld gimbal 100 meets the joint angle condition based on the current joint angle of each motor of the handheld gimbal 100; and determining whether the handheld gimbal 100 meets the mode switching condition based on a determination result of the handle part 101, a determination result of the first bracket 102, and/or a determination result of each motor of the handheld gimbal 100.

In some embodiments, current attitude information of the first bracket 102 may be determined by the set attitude acquisition element, and the current attitude information of the handle part 101 may be determined based on the current attitude information of the first bracket. Alternatively, both the first bracket and the handle part may be provided with the attitude acquisition elements, and the current attitude information of the first bracket 102 and the current attitude information of the handle part 101 may be determined by the respective attitude acquisition elements. By setting the attitude acquisition element on the first bracket 102, but not on the handle part 101, the device cost can be reduced, and accurate attitude information of the first bracket 102 and the handle part 101 can also be obtained. Further, by providing the attitude acquisition elements on both the first bracket 102 and the handle part 101, the attitude information of the handle part 101 does not need to be obtained through complicated calculations, and the attitude information of the first bracket 102 and the handle part 101 can be quickly obtained.

Step S103, controlling the handheld gimbal to perform a corresponding mode switching event when the handheld gimbal meets the mode switching condition.

When the handheld gimbal meets the mode switching condition, the controller may control the handheld gimbal 100 to execute the corresponding mode switching event. In one embodiment, when the handheld gimbal 100 is in a power-on state, the controller may control the handheld gimbal to be in a first control mode. Since the handle part 101 of the handheld gimbal 100 is generally in a vertical state, the back of the first bracket of the handheld gimbal 100 may face the front. That is, the screen of the shooting device mounted on the first bracket may face the user, such that it is convenient for the user to operation the handheld gimbal, and it is also convenient for the user to switch the first use mode of the handheld gimbal 100 to the other use modes, which greatly improves the convenience of switching the use modes.

The present disclosure also provides a gimbal control method, which can be applied to a shooting stabilizer. For example, the shooting stabilizer may be a handheld gimbal. The handheld gimbal may be selected as the handheld gimbal 100 as shown in FIG. 1. As shown in FIG. 1, the handheld gimbal 100 includes 1 handle part 101, a first bracket 102, a second bracket 103, a third bracket 104, a first motor 105, a second motor 106, and a third motor 107. The handle part 101 may include a plurality of use modes, and the plurality of use modes may correspond to a plurality of attitudes of the first bracket 102 respectively. Different use modes may correspond to different attitude, which is convenient for users to switch the handheld gimbal to a suitable use mode in a variety of use cases, which can improve the convenience of operation while ensuring the stability and clarity of the captured images.

In some embodiments, the first bracket 102 may be used to mount a payload, the second bracket 103 may be connected between the first bracket 102 and the third bracket 104, and the third bracket 104 may be used to connected with the handle part 101. The first motor 105 may be installed on the first bracket 102 and used to connect the first bracket 102 and the second bracket 103.

In some embodiments, one side of the second motor 106 may be installed on the second bracket 103, and the other side of the second motor 106 may be installed on the third bracket 104, such that the second motor 106 can drive the second bracket 103 to rotate. Further, one side of the third motor 107 may be installed on the third bracket 104, and the other side of the third motor 107 may be installed on the handle part 101, such that the third motor 107 can drive the third bracket 104 to rotate.

In some embodiments, when the handle part 101 is substantially in a vertical state, tilting the handle part 101 counterclockwise or clockwise to rotate the handle part 101 around the roll axis may cause the first motor 105 to follow the handle part 101 to rotate to drive the first bracket 102 to rotate around the roll axis; and/or, when the handle part 101 is substantially in a horizontal state, tilting the handle part 101 counterclockwise or clockwise to rotate the handle part 101 around the yaw axis may cause the first motor 105 to follow the handle part 101 to rotate to drive the first bracket 102 to rotate around the yaw axis.

It can be understood that when the handle part 101 is substantially in the vertical state, that is, the current axis direction of the handle part 101 may be substantially parallel to the direction of gravity, that is, the angle that the current axis direction of the handle part 101 deviates from the direction of gravity within a preset deviating angle range. When the handle part 101 is substantially in the horizontal state, the current axis direction of the handle part 101 may be substantially perpendicular to the direction of gravity, that is, the angle that the current axis direction of the handle part 101 deviates from the horizontal direction may be within the preset deviating angle range. In some embodiments, the preset deviating angle range may be between 0° to 45°. Further, the preset deviating angle range may be between 0° to 5°. It can be understood that in other embodiments, the term “substantially” is used to describe the orientation, and it also has a similar preset deviation angle range, which will not be repeated in the following description.

The gimbal control method can control the handheld gimbal to switch between different use modes, and it can also control the first bracket 102 of the handheld gimbal to follow the handle part 101, the second bracket 103, or the third bracket 104, and the attitude of the first bracket 102 may change with the change of attitude of the handle part 101, the second bracket 103, or the third bracket 104. The first bracket 102 can be used to mount a control terminal, such as a shooting device. The shooting device may be a smart phone, a camera, etc. In some embodiments, the first bracket 102 may also be integrated with the shooting device.

The control terminal may communicate with the handheld gimbal. The control terminal may be configured to control the handheld gimbal, and the handheld gimbal may enter a sleep mode. The specific method of the communication connection between the control and the handheld gimbal is not limited in the present disclosure. For example, wireless communication may be realized based on Bluetooth technology. In another example, wired communication connection may be realized based on communication interface such as RS-232.

The specific method for the handheld gimbal to enter the sleep mode in not limited in the present disclosure. For example, the user may trigger the handheld gimbal to enter the sleep mode through the control of a non-controlling terminal such as a button disposed on the handheld gimbal or through an internal mechanism of the handheld gimbal. Take the movable platform of the controlled device as a gimbal as an example. For example, the trigger condition for triggering the gimbal to enter the sleep mode may include, but is not limited to one or more of a buckled of the gimbal changing from an unbuckled state to a buckled state, or a first button being pressed based on a preset pressing rule. For example, the trigger condition for triggering the gimbal to enter an awake mode from the sleep mode may include one or more of a pressing of the first button based on a preset pressing rule, or double-clicking a second button. In some embodiments, the preset pressing rule may be flexibly designed. In some embodiments, the preset pressing rule may include, but is not limited to, one or more of a triple-clicking of the first button, and/or a long-press of the first button and the duration of the long-press being less than a duration threshold. In this way, it is convenient and quick for the movable platform to enter the sleep mode only by operating on the movable platform.

In some embodiments, the first button may support a one-key switching function of horizontal shooting and vertical shooting. In some embodiments, double-clicking the first button may trigger the one-key switching function of horizontal shooting and vertical shooting. In some embodiments, the second button may be a mode switching button, and the mode switching button may be used for switching between a portrait shooting mode and a landscape shooting mode of the movable platform of the gimbal.

In some embodiments, the first button may also support the function of calling up a shortcut menu. The user may operate the first button to call up the shortcut menu on the display interface of the control terminal, and change the shooting mode, the gimbal control mode, and enter a preview mode by operating on the first button, instead of operating on the display interface of the control terminal. The gimbal control mode may include a pan follow mode, a pitch lock mode, a FPV mode, etc. In this way, the user can achieve one-handed control of the handheld gimbal to facilitate user operations.

In some embodiments, the handheld gimbal may include a plurality of buttons. If there is no conflict, a plurality of operation buttons may be used to implement one or more of the above functions, which is not limited in the embodiments of the present disclosure.

In some embodiments, the to-be-followed object may be one of the handle part, the second bracket, or the third bracket of the handheld gimbal, and the attitude of the first bracket may change following the change of the attitude of the to-be-followed object. Through the mode type to which the current use mode belongs, the to-be-followed object of the first bracket of the handheld gimbal, that is, the camera, can be quickly and accurately determined, such that when the attitude of the to-be-followed object changes subsequently, the attitude of the first bracket can also change synchronously.

In some embodiments, the method for determining the mode type may include obtaining a mode identifier corresponding to the current use mode of the handheld gimbal, and determining an identifier set to which the mode identifier belongs; obtaining a mapping relationship table between a preset mode type and the identifier set, the mode type having a corresponding relationship with the identifier set; and determining the mode type to which the current use mode of the handheld gimbal belongs based on the identifier set and the mapping relationship table. That is, the mapping relationship table may be queried to obtain the mode type corresponding to the identifier set, and the obtained mode type may be used as the mode type to which the current use mode of the handheld gimbal belongs. It should be noted that the mapping relationship table between the preset mode type and the identifier set may be set based on actual situations, which is not limited in the embodiments of the present disclosure.

S202, if the attitude of the to-be-followed object changes, determining an expected attitude angle of the first bracket based on a current attitude angle of the to-be-followed object.

Specifically, if the attitude of the to-be-followed object changes, the handheld gimbal may determine the expected attitude angle of the first bracket based on the current attitude angle of the to-be-followed object. Specifically, the difference between the current attitude angle of the to-be-followed object and the historical attitude angle may be calculated, where the historical attitude angle may be the attitude angle of the to-be-followed object at a previous time. An attitude angle coefficient may be determined based on the difference between the current attitude angle of the to-be-followed object and the historical attitude angle, and the expected attitude angle of the first bracket may be determined based on the attitude angle coefficient and the difference between the current attitude angle of the to-be-followed object and the historical attitude angle. It should be noted that the current attitude angle of the to-be-followed object may include a yaw angle and a pitch angle, and the expected attitude angle of the first bracket may include the yaw angle and the pitch angle. That is, the attitude of the first bracket may change with the change of the yaw angle and pitch angle of the to-be-followed object.

In some embodiments, the method for determining the attitude angle coefficient may be the handheld gimbal obtaining a mathematical expression between a pre-stored difference and the attitude angle coefficient, substituting the difference between the current attitude angle of the to-be-followed object and the historical attitude angle into the mathematical expression to obtain a calculation result, and using the calculation result as an attitude angle system. It should be noted that the mathematical expression between the difference and the attitude angle coefficient described above may be set based on actual situations, which is not limited in the present disclosure.

In some embodiments, the method for obtaining the attitude angle of the to-be-followed object may be, when the to-be-followed object is not provided with an attitude acquisition element and the first bracket is provided with an attitude acquisition element, using the handheld gimbal to obtain the attitude angle of the first bracket through the attitude acquisition element, and obtain joint angle data; and using the current attitude angle of the first bracket and the joint angle data to inversely calculate the attitude angle of the to-be-followed object. Further, when the to-be-followed object is provided with an attitude acquisition element, using the handheld gimbal to obtain the attitude angle of the to-be-followed object through the set attitude acquisition element.

S203, adjusting the attitude angle of the first bracket based on the current attitude angle and the expected attitude angle until the adjusted attitude angle of the first bracket is the expected attitude angle.

After determining the expected attitude angle of the first bracket, the handheld gimbal may adjust the attitude angle of the first bracket based on the current attitude angle and the expected attitude angle of the first bracket until the adjusted attitude angle of the first bracket is the expected attitude angle. In some embodiments, the first bracket may be provided with an attitude acquisition element, the current attitude angle of the first bracket may be determined by the set attitude acquisition element, and the current attitude angle of the handle part may be determined by inverse calculation of the current attitude angle of the first bracket. Alternatively, both the first bracket and the handle part may be provided with an attitude acquisition element, and the current attitude angle of the first bracket and the current attitude angle of the handle part may be determined by the respective set attitude acquisition elements. By arranging the attitude acquisition element on the first bracket, but not the handle part, the cost of the device can be reduced, and an accurate attitude angle of the first bracket and the handle part can also be obtained. Further, by arranging the attitude acquisition elements on both the first bracket and the handle part, the attitude angle of the handle part may not need to be obtained through complicated calculations, and the attitude angles of the first bracket and the handle part can be quickly obtained.

Specifically, the attitude deviation value of the first bracket may be determined based on the current attitude angle and the expected attitude angle of the first bracket, and an attitude adjustment instruction of the first bracket may be generated based on the attitude deviation value. That is, a pre-stored attitude deviation value and a rotation speed mapping relationship table may be obtained, the corresponding rotation speed may be determined based on the mapping relationship table and the attitude deviation value, and the attitude adjustment instruction of the first bracket may be generated based on the rotation speed. Based on the attitude adjustment instruction, the attitude angle of the first bracket can be adjusted until the adjusted attitude angle of the first bracket is the expected attitude angle. It should be understood that the attitude adjustment instruction can be used to control the rotation of the first bracket to drive the rotation of the first bracket, thereby adjusting the attitude angle of the first bracket. The mapping relationship table between the attitude deviation value and the rotation speed described above can be set based on actual situations, which is not limited in the present disclosure. Through the method described above, the first bracket can be smoothly adjusted to follow the determined to-be-followed object, which can effectively ensure the stability of shooting and improve the user experience.

In some embodiments, in the process of adjusting the attitude angle of the first bracket, whether the difference between the expected attitude angle and the adjusted attitude angle of the first bracket is greater than a preset threshold may be determined at a preset time interval. If the difference is greater than the preset threshold, the attitude adjustment instruction may be updated based on the difference, and the attitude angle of the first bracket may be adjusted based on the updated attitude adjustment instruction. If the difference is less than or equal to the preset threshold, the adjusted attitude angle of the first bracket may be determined as the expected attitude angle. It should be noted that the preset time interval described above can be set based on actual situations, which is not limited in the present disclosure. By updating the attitude adjustment instruction through the difference between the expected attitude angle and the attitude angle of the adjusted first bracket, the first bracket can follow the determined to-be-followed object smoothly and quickly, which can effectively ensure the stability of the shooting and improve the user experience.

In some embodiments, the method for adjusting the attitude adjustment instruction based on the difference may be obtaining the rotation speed corresponding to the difference, and determining whether the rotation speed is less than a preset speed threshold; updating the attitude adjustment instruction based on the rotation speed if the rotation speed is less than the preset speed threshold; and updating the attitude adjustment instruction based on the preset speed threshold if the rotation speed is greater than or equal to the preset speed threshold. By setting a maximum rotation speed, the first bracket can be controlled to follow the determined to-be-followed object smoothly and quickly, which can effectively ensure the stability of the shooting and improve the user experience.

In the gimbal control method provided in the foregoing embodiment, the to-be-followed object of the first bracket can be determined through the current use mode of the handheld gimbal. When the attitude of the to-be-followed object changes, the attitude angle of the first bracket can be adjusted such that the attitude of the first bracket can change following the change of the attitude of the to-be-followed object. In different types of use modes, the to-be-followed object can be different, which can greatly improve the accuracy of following, ensure the stability of the shooting, and greatly improve the user experience.
