Distance measurement method, movable platform, equipment and storage medium

Abstract

The invention discloses a distance measurement method, a movable platform, equipment and a storage medium. The method comprises the steps of obtaining a first image of an airspace above an unmanned aerial vehicle; after semantic recognition, obtaining a target area influencing flight of the unmanned aerial vehicle; controlling the unmanned aerial vehicle to move a preset distance in a specified direction to obtain a second image of the airspace above the unmanned aerial vehicle; matching pixel points of the target area in the first image and the second image to obtain matched pixel points; finally, determining the distance between the target area and the unmanned aerial vehicle according to the matched pixel points, and furthermore, controlling the flight state of the unmanned aerial vehicle according to the distance. Distance measurement is carried out through image recognition, and the used images are shot by a camera necessary for the unmanned aerial vehicle, so that distance measurement can also be realized for the unmanned aerial vehicle without a depth sensor.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a distance measurement method, a movable platform, equipment and a storage medium. 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 in the return phase of the UAV, the UAV has a process of rising and flying during this stage. Therefore, it is necessary to detect the distance between the UAV and the area above the UAV that affects its flight, so as to determine the Whether the area affects the drone's ascent flight, where obstacles are usually contained in this area.

AI Technical Summary

Problems solved by technology

However, when the UAV is not equipped with a ranging sensor device, the distance measurement cannot be realized, so that there is a greater risk of damage to the UAV during the return process.
