Document Type and Number:
WIPO Patent Application WO/2020/233682
Kind Code:
A1
Abstract:
The present invention relates to the technical field of unmanned aerial vehicles. Particularly disclosed are an autonomous circling photographing method and apparatus and an unmanned aerial vehicle. The unmanned aerial vehicle comprises a binocular camera assembly. The method comprises: obtaining, with the binocular camera assembly, a target photographed picture and a circled object selected by a user from the target photographed picture; obtaining the flight height of the unmanned aerial vehicle when the unmanned aerial vehicle obtains the target photographed picture; determining a spatial distance between the binocular camera assembly and the circled object based on the target photographed picture; detecting the optical axis direction of the binocular camera assembly in real time; and carrying out autonomous circling photographing according to the flight height, the spatial distance and the optical axis direction, detected in real time, of the binocular camera assembly. According to the technical solution, on the one hand, autonomous circling photographing can be carried out in areas with weak GPS signals such as an indoor area, and on the other hand, the autonomous circling photographing quality of the unmanned aerial vehicle can be guaranteed.
