Method and device for controlling unmanned aerial vehicle homing

Abstract

The invention provides a method and device for controlling unmanned aerial vehicle homing. The method and device are applied to an unmanned aerial vehicle control station on the ground. The unmanned aerial vehicle control station stores an electronic map. The method comprises the steps that if an unmanned aerial vehicle is started to take off from the take off position to start operating, and theflying states of the unmanned aerial vehicle are monitored and comprise the normal operating flying state and the fault suspension state; when the unmanned aerial vehicle is in the fault suspension state, and the path between the current suspension position and the take off position of the unmanned aerial vehicle is obtained on the electronic map; position coordinates of an obstacle correspondingto the suspension position is obtained on the electronic map; whether the obstacle exists in the path or not is judged according to the position coordinates of the obstacle; and if the obstacle exists, The unmanned aerial vehicle is controlled to adjust the position where the unmanned aerial vehicle is located so as to control the unmanned aerial vehicle to conduct homing along the path suitable for homing. The situation that a sensor for homing is arranged on the unmanned aerial vehicle is avoided, thus the manufacturing cost is saved, the path avoiding the obstacle is selected before homingof the unmanned aerial vehicle, and thus the homing efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of unmanned aerial vehicles, in particular to a method and device for controlling the return of unmanned aerial vehicles. Background technique [0002] When the UAV is operating, it generally obtains the geographic information of the location first, and then plans the route according to the parameters set by the user. During the operation, the task is automatically executed according to the planned route. During the automatic flight, if there is an emergency (such as low battery power, sensor abnormality, etc.), it is necessary to return to the drone’s take-off position. [0003] There may be obstacles on the return path. The existing technology generally carries obstacle avoidance sensors (such as radar, ultrasonic sensor, infrared sensor, etc.) on the UAV. When the obstacle avoidance sensor detects an obstacle, the UAV hovers Wait for instructions from ground control to avoid hitting obstacles. ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the UAV must carry high-cost obstacle avoidance sensors, which increases the operating cost of the UAV; and when the UAV encounters an obstacle, it hovers in mid-air and needs manual intervention to return to the take-off position , also reduces the return efficiency
