As shown in FIG. 1 , the location service method according to the embodiment of the present application includes steps S110 to S130.

S110. Obtain the target position.

In some implementation manners, the acquiring the target position includes: acquiring the positioning position of the terminal device. It can be understood that the target position may be the current position of the user, and the user may obtain information of flight locations near the current position.

In other implementations, the acquiring the target position includes: determining the target position according to a user's position determination operation.

Exemplarily, the user may determine the target location through a location determination operation, for example, by dragging a positioning icon on the map to a specific location, clicking on a specific location on the map, or inputting a specific location through a key or voice, so as to determine the specific location. As the target position, of course, it is not limited to this. For example, when the user needs to photograph the flight at the position B, the position B can be determined as the target position through the position determination operation.

Locations A and B where aerial photography is possible.

As shown in FIG. 4 , it is determined that the position S is the positioning position of the terminal device, and the position B is determined to be the target position. The display device of the terminal device displays the information of the flight locations near the target position B, including the positions a and b that can be taken off. , c, d, e, f and/or positions A, B where aerial photography is possible.

S120. Determine the flight aggregation information corresponding to the target position, where the flight aggregation information includes flight heat information of several aggregation positions, and the flight aggregation information is based on the take-off position or aerial photography position in the multiple flight data of the unmanned aerial vehicle. aggregated.

S130. Display the flight aggregation information corresponding to the target position on the display device of the terminal device.

Exemplarily, as shown in FIG. 3 and FIG. 4 , the aggregation positions include positions a, b, c, d, e, f and/or positions A and B, and the flight heat information is used to indicate the unmanned aerial vehicle at the aggregation position. historical flight data, such as the number of takeoffs at the aggregated location and/or the number of aerial photography missions performed at the aggregated location.

In some embodiments, the flight heat information includes the number of flights and/or a heat graphic mark, and the color and/or size of the heat graphic mark is determined according to the number of flights corresponding to the aggregated location.

Exemplarily, the flight heat information includes the number of takeoffs. As shown in FIG. 4 , the number of takeoffs at the aggregated positions a, b, c, d, e, and f is displayed, wherein the number of unmanned aerial vehicles taking off at position f is 600.

Exemplarily, the flight aggregation information includes a flight heat map, and the flight heat map includes heat graphic identifiers located at the plurality of aggregation locations.

Exemplarily, the server may obtain the flight heat map by visualizing the flight times of the several aggregated positions. For example, the color and/or size of the heat graphic logo of each aggregation location can be determined according to the number of flights at each aggregation location, and the flight heat map can be obtained by setting a heat graphic logo corresponding to the color and/or size at each aggregation location.

Exemplarily, the flight heat information includes a heat graphic identifier. As shown in FIG. 3 , a circular heat graphic identifier showing aggregation positions a, b, c, d, e, and f, wherein the larger the circle, the more the aggregation position. The more the number of takeoffs is, for example, the largest circular heat graph in Figure 3 identifies the position f, which means that in the area near the current position S, there are more UAVs taking off at the position f. It can be understood that the heat graphic logo is not limited to being circular, for example, it can also be square, cylindrical, and the like.

Exemplarily, the number of flights corresponding to the aggregated location may be displayed on the heat graphic identifier, such as a circle, to facilitate the user's understanding.

Exemplarily, the user may control the unmanned aerial vehicle to perform a flight mission at the corresponding aggregated position or a short distance from the aggregated position according to the displayed flight aggregation information corresponding to the target position, such as taking off at position f.

Exemplarily, the aggregation position includes a first aggregation point of take-off positions, and the number of flights at the aggregation position includes the number of take-offs at the take-off position corresponding to the first aggregation point.

For example, in FIG. 3 and FIG. 4 , the aggregation positions include aggregation points a, b, c, d, e, and f of take-off positions, and the number of flights at position f may include the number of take-offs at the take-off position corresponding to position f.

Exemplarily, the take-off position corresponding to the first aggregation point includes a take-off position whose distance from the first aggregation point is less than or equal to a threshold. For example, if there are 600 sorties of UAVs taking off at different positions, but the distances from these positions to position f are less than or equal to the threshold, it can be determined that the number of take-offs for position f is 600.

Exemplarily, the first aggregation point is obtained by aggregating several take-off positions. For example, if there are 600 unmanned aerial vehicles taking off at different positions, but these positions are aggregated to obtain the aggregation point f, the position can be determined. The number of takeoffs for f is 600.

Exemplarily, the number of aerial shots and/or the heat graphic logo of the corresponding aerial photography positions may be displayed at position A and position B, and the color and/or size of the heat graphic logo is determined according to the number of aerial shots corresponding to the aggregated positions. There are many second aggregation points, and the color of the heat graphic logo is more red.

In some embodiments, the server may acquire flight data of the UAV, the flight data including the take-off position and/or the aerial photographing position of the UAV flying; The location is aggregated to obtain the flight aggregate information.

Exemplarily, by performing point aggregation processing on the take-off positions or aerial photography positions in the plurality of flight data, several aggregated positions and the number of flights at each of the aggregated positions are obtained.

Specifically, the server may send the flight aggregation information to the terminal device of the unmanned aerial vehicle, so that the terminal device displays the flight aggregation information.

Exemplarily, the server may acquire flight data of multiple sorties of unmanned aerial vehicles, where the flight data includes take-off positions and/or aerial photography positions. By performing point aggregation processing on the take-off positions in the multiple flight data, the first aggregation point and the number of take-offs of the first aggregation point can be obtained; The number of aerial shots of the second aggregation point and the second aggregation point.

By performing point aggregation on take-off positions or aerial photography positions in a large amount of flight data to obtain a small number of aggregated positions, and the number of take-offs or aerial photography for each of the aggregated positions, the problem of visualizing a large number of point marks in the map can be solved, and the problem of visualizing a large number of point marks in the map can be solved in a more efficient manner. An effective way to transmit or express the distribution of the take-off position or aerial photography position, and the information display is clearer and clearer.

Exemplarily, the point aggregation processing includes at least one of the following: grid-based point aggregation processing, distance-based point aggregation processing, grid and distance-based point aggregation processing, and K-means-based point aggregation processing.

Understandably, each location can be represented as a point on the map.

Among them, the algorithm principle of grid-based point aggregation processing is to first divide the visible area of the map into a square grid of fixed size, and then aggregate the points in the same grid into the square grid. The default aggregation point is set to The center of the square; there is one aggregation point in each square grid after the final aggregation, and the number of points contained in the square grid can be obtained.

The algorithm principle of distance-based point aggregation processing is to judge aggregation according to the distance between points. Iteratively calculate the distance for each point. If the distance between the iterative point and the quasi-aggregation point is within the specified threshold range, then the iterative point will be aggregated to this point, otherwise it will be used as a new aggregation point; after each aggregation A new aggregation point needs to be recalculated. The new aggregation point is the center point of the iterative point and the aggregated point. In this cycle, the final aggregation point is the center point of multiple points after multiple iterations.

The grid and distance-based point aggregation process first takes each point as the center of the square, and wraps a square with a fixed side length, and the side length is the default value initially set by the user; then iterates the outsourced square of each point; If the outer square of the point intersects with the outer square of the existing aggregation point, the iteration point is aggregated into the aggregation point; if the outer square of the iteration point intersects with the outer squares of multiple known aggregation points, then compare the point to The distance of each aggregation point is aggregated into the aggregation point with a relatively short distance; if it does not intersect, a new aggregation point is created, and so on, until all the original points have been traversed.

The algorithm principle of point aggregation processing based on K-means is to use the distance between two points as a fusion index, and aggregate objects with a short distance.

Exemplarily, when the point aggregation processing includes grid-based point aggregation processing or grid and distance-based point aggregation processing, the size of the grid corresponds to a square with a side length of 100-200 meters. The side length corresponds to the length when the map scale is 1:1. When the grid size is within this range, the distribution density of aggregation locations is more appropriate, which not only facilitates users to clearly understand the number of takeoffs or aerial shots at each aggregation location, but also facilitates users to accurately find the desired aggregation location. In one embodiment, the grid is a square area with a side length of 160 meters, and the landscapes captured by multiple take-off locations in this area will not be very different, nor will the division be too small to cause too many aggregation points. dense.

In some implementations, the target position may be sent to a server, and the server obtains the target position of the terminal device, and sends the flight aggregation information corresponding to the target position to the terminal device of the UAV, so that the terminal device can obtain the target position from the terminal device.
