Referring to
At step 201, multiple sampling points, curves, straight lines, or block diagrams of a strip-shaped geographical region are acquired.
In a specific implementation, the embodiment of the steps of the method for planning a navigation region of an unmanned aerial vehicle according to the present disclosure may be applied to a remote control of an unmanned aerial vehicle to control a terminal for performing flight, agricultural plant protection and other operations of the unmanned aerial vehicle.
In other embodiments, the embodiment of the steps of the method for planning a navigation region of an unmanned aerial vehicle may also be applied to PC terminals, cloud servers, and the like.
The unmanned aerial vehicle may refer to an aircraft that uses a wireless remote control or program control to perform a specific aviation mission, such as a drone configured for agricultural plant protection and surveying. The unmanned aerial vehicle is generally not equipped with an operator, uses aerodynamics to provide the aircraft with the required lift, and can automatically fly or can be remotely guided.
Further, the remote control may be a mobile terminal installed with a control program, such as a mobile phone. At this time, the remote control is also referred to as a ground station.
The remote control may also be a stand-alone device with components such as a processor, a power management chip, a battery, a Universal Serial Bus (USB) interface, a button component, and a joystick component.
A data line may access to the USB interface to connect the mobile terminal for business operations cooperatively.

The button component may include a stepping button and a function button, configured to control the flight attitude of the unmanned aerial vehicle and related business operations of the unmanned aerial vehicle step by step.
In the embodiment of the present disclosure, an electronic map may be displayed in the remote control, and a region to be surveyed may be displayed in the electronic map. The region to be surveyed may be a strip-shaped geographical region, such as a river or a road. A user may draw a surveying pattern in the strip-shaped geographical region by operations such as a touch operation. End points and inflection points are selected as sampling points in the surveying pattern. The user may directly mark a surveying region by using a curve, a straight line, a block diagram, or the like in a satellite map.
For example, as shown in
Of course, the manner of acquiring the sampling points is only an example. When the embodiment of the present disclosure is implemented, the manner of acquiring other sampling points may be set according to actual conditions, for example, the user collects sampling points through a surveying apparatus, and the like. This is not limited by the embodiment of the present disclosure. Besides, in addition to the manner of acquiring the sampling points, those skilled in the art may also adopt other sampling point acquisition manners according to actual needs, which is not limited in the embodiment of the present disclosure.
At step 202, a target surveying pattern is determined according to the multiple sampling points, curves, straight lines, or block diagrams.
In a specific implementation, the sampling points may be converted into a regular target surveying pattern according to a certain drawing rule.
In an embodiment of the present disclosure, step 202 may include the following sub-steps.
At sub-step S11, the multiple sampling points are connected in a drawing order to generate a target surveying pattern.
In the embodiment of the present disclosure, multiple sampling points may be sequentially connected according to a sampling order, and the multiple sampling points are sequentially connected to generate a target surveying pattern such as a broken line.
For example, as shown in
As shown in
Of course, the above surveying pattern and the target surveying pattern are only examples. When the embodiment of the present disclosure is implemented, other surveying patterns and target surveying patterns may be set according to actual conditions. For example, the surveying pattern is a contour of a strip-shaped geographical region, and an irregular closed pattern. The target surveying pattern is a rectangle, an irregular polygon, a simulated curve, a discrete point, a point set, and the like, which are not limited by the embodiment of the present disclosure. Besides, in addition to the surveying pattern and the target surveying pattern, those skilled in the art may also adopt other surveying patterns and target surveying patterns according to actual needs, which is not limited in the embodiment of the present disclosure.
At step 203, a flight operation region is generated for the strip-shaped geographical region according to a trend of the target surveying pattern.
In an embodiment of the present disclosure, the flight operation region may be generated along the trend of the target surveying pattern, that is, the flight operation region covering the strip-shaped geographical region is generated along the trend of the strip-shaped geographical region.
In an embodiment of the present disclosure, step 203 may include the following sub-steps.
At sub-step S21, a trend line is generated along the trend of the target surveying pattern.
In the embodiment of the present disclosure, a trend line may be generated along the trend of the target surveying pattern to characterize the trend of the strip-shaped geographical region. For example, the trend line may be a straight line or a simulated curve.
In an embodiment of the present disclosure, sub-step S21 may further include the following sub-steps.
At sub-step S211, a reference point is determined in the target surveying pattern.
In a specific implementation, according to the characteristics of the target surveying pattern, a certain point may be determined as a reference point in the target surveying pattern, such as a center point of gravity, a center point, or an orthocenter point.
In an example of the embodiment of the present disclosure, the reference point includes a midpoint, and sub-step S211 may further include the following sub-steps.
At sub-step S2111, coordinates of the multiple sampling points are queried. The coordinates of the sampling point may be geographical coordinates acquired from an actual measuring apparatus, or may be geographical coordinates acquired from a map.
At sub-step S2112, an average value of the coordinates of the multiple sampling points is calculated as coordinates of the midpoint.
In the present example, for a target surveying pattern such as a broken line, an average value of the coordinates of each sample point may be used as the coordinates of the midpoint to determine the position of the midpoint.
For example, as shown in
At sub-step S212, a trend line passing through the reference point is generated along the trend of the target surveying pattern.
In the embodiment of the present disclosure, a trend line may be generated along the trend of the target surveying pattern through the reference point.
In an example of the embodiment of the present disclosure, sub-step S212 may further include the following sub-steps.
At sub-step S2121, extreme coordinates of the target surveying pattern are assigned to extreme points.
In a specific implementation, a bounding rectangle generated by the target surveying pattern is generally a Minimum Bounding Rectangle (MBR), the extreme coordinates of the target surveying pattern are obtained by a corner point of the bounding rectangle, such as maximum X coordinates, minimum X coordinates, maximum Y coordinates, or minimum Y coordinates, and the extreme coordinates are merged as an extreme point.
For example, the maximum X coordinates and the maximum Y coordinates are assigned to one extreme point, and the minimum X coordinates and the minimum Y coordinates are assigned to the other extreme point.
At sub-step S2122, the extreme points are connected to obtain a reference line segment.
In practical applications, the extreme points may be connected to represent a trend of the target surveying pattern as a reference line segment.
At sub-step S2123, a trend line parallel to the reference line segment is generated through the reference point.
In the present example, after passing through the reference point, a line segment parallel to the reference line segment may be generated as a trend line.
For example, as shown in
The slope between the sampling point P1 and the sampling point P6 represents the trend of the target surveying pattern P1P2P3P4P5P6, the slope between the diagonal points BC conforms to the trend, and the slope between the diagonal points AD is not in line with the trend, so that the diagonal line BC is taken as the reference line segment, and a line segment 1 parallel to the diagonal line BC is made as the trend line through the midpoint O.
Further, when the trend line is generated, it is assumed that the diagonal point is a first corner point and a second corner point, and the trend line has a first positioning point and a second positioning point.
Then a first slope of a line connecting the first corner point and the midpoint may be calculated, and it is judged whether the first slope is greater than 1. If yes, the vertical coordinates of the first corner point are assigned to the vertical coordinates of the first positioning point. If not, the horizontal coordinates of the first corner point are assigned to the horizontal coordinates of the first positioning point.
Similarly, a second slope of a line connecting the second corner point and the midpoint may be calculated, and it is judged whether the second slope is greater than 1. If yes, the vertical coordinates of the second corner point are assigned to the vertical coordinates of the second positioning point. If not, the horizontal coordinates of the second corner point are assigned to the horizontal coordinates of the second positioning point.
Since the slope between the first positioning point and the second positioning point is the same as the slope of the reference line segment, in combination with the coordinates of the midpoint, the coordinates of the first positioning point and the second positioning point may be calculated to determine the trend line.
At sub-step S22, a flight operation region is generated for the strip-shaped geographical region by taking the trend line as a positioning reference.
In a specific implementation, the trend line may be used as a positioning reference of the flight operation region, thereby generating the flight operation region, so that the flying operation conforms to the trend of the target surveying pattern, thereby conforming to the trend of the strip-shaped geographical region.
In an embodiment of the present disclosure, the flight operation region includes one or more sub-operation regions, and sub-step S22 may further include the following sub-steps.
At sub-step S221, an operation width covering the target surveying pattern is calculated.
In practical applications, the operation width covering the target surveying pattern may be calculated to cover the strip-shaped geographical region.
In an example of the embodiment of the present disclosure, sub-step S221 may include the following sub-steps.
At sub-step S2211, a vertical distance from each point in the target surveying pattern to the trend line is calculated.
At sub-step S2212, twice the sum of a maximum vertical distance and a preset buffer distance is set as the operation width.
In the present example, a user may pre-set a buffer distance according to the strip-shaped geographical region, so that the operation width may cover the strip-shaped geographical region.
For example, for a river, a buffer distance of 25 meters may be set. In a specific implementation, the vertical distance from each point in the target surveying pattern to the trend line may be calculated. If the target surveying pattern is a broken line, the vertical distance from each sampling point to the trend line may be calculated.
On the basis of the vertical distance with the largest median in all vertical distances, in combination with the buffer distance, it may be half of the operation width, and twice its value may be set as the operation width.
For example, it is assumed that in the target surveying pattern P1P2P3P4P5P6, the vertical distances of the sampling points P1, P2, P3, P4, P5, and P6 to the trend line 1 are respectively q1, q2, q3, q4, q5, and q6, where the value of q3 is the largest, the buffer distance is H, and the operation width is d=2*(q3+H).
Of course, the calculation manner of the above operation width is only an example. When the embodiment of the present disclosure is implemented, the calculation manner of other operation widths may be set according to actual conditions. For example, twice the vertical distance with the largest median in all vertical distances is used as the operation width, the sum of the vertical distances with the largest values on both sides of the trend line is taken as the operation width, and on the basis of the sum of the vertical distances with the largest values on both sides of the trend line, in combination with twice the buffer distance, it is used as the operation width, etc., which is not limited by the embodiment of the present disclosure.
At sub-step S222, an operation length of the unmanned aerial vehicle flying under the operation width is calculated.
In a specific implementation, the area in which the unmanned aerial vehicle can fly at a time is determined, and therefore, by dividing the area by the operation width, the operation length of one-time flight may be obtained.
At sub-step S223, the operation length is taken and the operation width is expanded sequentially on the trend line to generate a sub-operation region of a single flight operation.
The expansion is performed on the basis of the trend line, and the expansion width is the operation width, so that the generated sub-operation region may cover part of the target surveying pattern, thereby covering part of the strip-shaped geographical region. The multiple sub-operation regions overlap as the entire flight operation region.
In an example of the embodiment of the present disclosure, sub-step S223 may further include the following sub-steps.
At sub-step S2231, the trend line is set as a center line of the sub-operation region.
In the present example, the trend line is the centerline of the entire flight operation region, and is also the centerline of each sub-operation region, and the flight operation region (including each sub-operation region) is symmetrical about the trend line.
At sub-step S2232, an operation starting point is sequentially determined in the trend line.
In a specific implementation, the operation starting point of the trend line is a point of a first projection of the target surveying pattern in the trend line, or, an operation end point of the previous sub-operation region.
For example, if the target surveying pattern is a broken line, a point of the first target surveying pattern projected to the trend line is the first operation starting point.
At sub-step S2233, the operation length is taken from the operation starting point and an operation end point is determined sequentially to obtain a sub-center line segment.
In practical applications, the operation end point is a point on the trend line spaced from the operation starting point by the operation length, or, a point of the last projection of the target surveying pattern on the trend line.
For example, if the target surveying pattern is a broken line, a point of the last target surveying pattern projected to the trend line is the last operation end point.
On the trend line, a line segment between the operation starting point and the operation end point is a sub-center line segment.
At sub-step S2234, half of the operation width is sequentially expanded in a vertical direction of the sub-center line segment respectively to obtain a sub-operation region of a single flight operation.
If the operation width is obtained by adding twice the buffer distance on the basis of the vertical distance with the largest median in all vertical distances, half of the operation width may be expanded on the basis of the sub-center line segment to ensure that the target surveying region may be covered.
For example, as shown in
Further, the coordinates of the operation starting point mi and the operation starting/end point m2 are known, and the operation width d/2 is known. It is assumed that k1, k2, k3, and k4 are four corner points of the sub-operation region N1, the distance of k1m1 is d/2, and the product of the slope of k1m1 and the slope of m1m2 is −1. Combining the two conditions, the coordinates of k1 may be calculated. Similarly, the coordinates of k2, k3 and k4 may be calculated, thereby determining the sub-operation region N1.
Similarly, as shown in
As shown in
Of course, the above generation manner of the sub-operation region is only an example. When the embodiment of the present disclosure is implemented, other generation manners of the sub-operation region may be set according to actual conditions. For example, on both sides of the vertical direction of the sub-center line segment, the expansion is performed according to the maximum vertical distance or the sum of the maximum vertical distance and the buffer distance respectively, which is not limited by the embodiment of the present disclosure.
In the embodiments of the present disclosure, multiple sampling points, curves, straight lines, or block diagrams of a strip-shaped geographical region are acquired, a target surveying pattern is determined according to the multiple sampling points, curves, straight lines, or block diagrams, and a flight operation region is generated for the strip-shaped geographical region according to a trend of the target surveying pattern. The present disclosure adapts to a trend of a strip-shaped geographical region in order to generate a flight operation region, and is highly flexible. The present disclosure targets the strip-shaped geographical region, such that regions other than the strip-shaped geographical region are not regarded as part of the flight operation region in order to reduce the number of flight operations of an unmanned aerial vehicle, thereby reducing flight operation costs.
It is to be noted that, for the method embodiments, for the sake of simple description, they are all expressed as a series of action combinations, but those skilled in the art should understand that the embodiments of the present disclosure are not limited by the described action sequence, because certain steps may be performed in other sequences or concurrently in accordance with the embodiments of the present disclosure.
