Example Embodiment

[0049] Example one

[0050] Please refer to figure 1 The first embodiment of the present invention is: a route planning method for surveying and mapping drones, which specifically includes the following steps:

[0051] S1. Input and obtain the longitude and latitude coordinate information of each vertex of the polygon target area to be surveyed, and determine the target surveying and mapping 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 according to the boundary of the original target area. The extension distance can be set according to the actual situation to ensure that the surveying and mapping drone can capture as much as possible the comprehensive target area information during the mission. .

[0052] S2. Use the sensors on the drone to collect the drone'...

Example Embodiment

[0061] Example two

[0062] The embodiment of the present invention relates to a surveying and mapping drone route planning device, which corresponds to the method in the first embodiment, and includes:

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

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

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

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

[0067] Calculation module, used to generate position information of each waypoint;

[0068] Return home processing module, used to determine the location information of the home return point and landing point;

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

[0070] The adjustment module, if the sensing module detects t...

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. ...
