Unmanned aerial vehicle return control method and device, movable platform and storage medium

Abstract

The invention discloses an unmanned aerial vehicle return control method and device, a movable platform and a storage medium. The method comprises: acquiring a first environment image in a return direction of an unmanned aerial vehicle (S101); if the first environment image contains an obstacle that does not affect normal flight of the unmanned aerial vehicle, responding to a first flight control instruction, so that the unmanned aerial vehicle flies according to a first preset mode (S102); determining a distance between the obstacle and the unmanned aerial vehicle according to a second environment image obtained in a flight process of the unmanned aerial vehicle in the first preset mode (S103); and if the distance is greater than the preset distance, responding to the return instruction to enable the unmanned aerial vehicle to return (S104). Visibly, in the method, the process of detecting whether an obstacle exists in the return direction of the unmanned aerial vehicle exists or not exists, and the return safety of the unmanned aerial vehicle is preliminarily guaranteed through the detection. On the basis, the distance between the obstacle and the unmanned aerial vehicle is calculated according to the environment images, and whether the unmanned aerial vehicle can return is determined according to the distance, so that the return safety of the unmanned aerial vehicle is further ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular to a control method, equipment, movable platform and storage medium for the return flight of an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. Compared with manned aircraft, it has the characteristics of small size and low cost. It has been widely used in many fields, such as street view shooting, power inspection, traffic monitoring, post-disaster rescue and so on. [0003] At all stages of drone flight, obstacles need to be avoided. Especially the return phase of the UAV. During the return process, the UAV usually first flies a certain distance along the return direction, such as flying upwards for a while, and then returns. Taking the upward flight as an example, during the upward flight, it is necessary to distinguish whether there is ...

Problems solved by technology

[0004] In the existing technology, it is usually assumed that there are no obstacles in the area above the UAV, but this method is obviously unreasonable, and it brings a greater risk of damage to the UAV during the return process
