Problems solved by technology

Under normal circumstances, it is necessary to calculate the waypoint information of the surveying and mapping UAV in advance. The existing technology mostly relies on manual field inspection and calculation to complete. Affected, on the other hand, the restriction of the target area is relatively large, and when the target area is an irregular shape, the calculation work is difficult to implement

Embodiment 1

[0050] Please refer to figure 1 , Embodiment 1 of the present invention is: a method for route planning of a surveying and mapping unmanned aerial vehicle, specifically comprising the following steps:

[0051] S1. Input and obtain the latitude and longitude coordinate information of each vertex of the polygon target area to be surveyed and mapped, and determine the target surveyed and mapped area. The target area can be selected in real time on the map, and the selected area can be any polygon, which can fully describe the object being surveyed and mapped. Before determining the target surveying and mapping area, it is necessary to extend a certain distance outward according to the boundary of the original target area. The extended distance can be set according to the actual situation to ensure that the surveying and mapping drone can capture comprehensive target area information as much as possible during the mission. .

[0052] S2. Use the sensors on the UAV to collect the...

Embodiment 2

[0062] An embodiment of the present invention relates to a route planning device for a surveying and mapping UAV, which corresponds to the method in Embodiment 1, including:

[0063] The input terminal is used to obtain the coordinate information of the target area to be mapped;

[0064] The preprocessing module is used to perform an extension process on the coordinate information of the input target area;

[0065] The sensing module is used to sense the current state parameters and flight environment of the UAV;

[0066] The collection module is used to collect shooting parameters of the camera;

[0067] A computing module, configured to generate position information of each waypoint;

[0068] The return processing module is used to determine the position information of the return point and the landing point;

[0069] The route generation module is used to generate the final route.

[0070] The adjustment module, if the sensing module detects that the current flight envir...

Abstract

The invention discloses an airline planning method for a surveying and mapping unmanned aerial vehicle. The airline planning method comprises the following steps: S1: determining a target surveying and mapping area; S2: determining the initial position and the heading angle of the unmanned aerial vehicle; S3: determining a flight strip interval and flight height; S4: according to target area information obtained in the S1 and initial position data of the unmanned aerial vehicle obtained in the S2, generating longitude and latitude coordinates of all waypoints capable of completely covering the target surveying and mapping area; S5: determining a landing point and a landing direction, and generating a longitude and latitude coordinate of a homeward voyage waypoint and a longitude and latitude coordinate of a landing waypoint; S6: connecting the longitude and latitude coordinates of all waypoints, and combining with the flight height obtained in the S3 to generate an airline. The invention also discloses an airline planning device for the surveying and mapping unmanned aerial vehicle. The airline planning device comprises an input end, a sensing module, a collection module, a calculation module, a homeward voyage processing module and an airline generation module.

Description

technical field [0001] The invention relates to unmanned aerial vehicle surveying and mapping technology, in particular to a surveying and mapping unmanned aerial vehicle route planning method and device. Background technique [0002] In the traditional UAV surveying and mapping work, it is usually necessary to analyze the surveying and mapping target area in the early stage of the UAV flight, plan the UAV route according to the surveying and mapping requirements, and upload the planning information to the UAV for unmanned aerial vehicles. Man-machines perform surveying and mapping tasks. Under normal circumstances, it is necessary to calculate the waypoint information of the surveying and mapping UAV in advance. The existing technology mostly relies on manual field inspection and calculation to complete. On the other hand, the limitation of the target area is relatively large, and the calculation work is difficult to implement when the target area is an irregular shape. ...
