Abstract

A terrain prediction method and device of a slope, a radar, an unmanned aerial vehicle and an operation control method are provided. The unmanned aerial vehicle is equipped with the radar. The methodincludes: acquiring the omnidirectional scanning area detection data obtained by the radar during the ground rotation scanning process (S110); fitting the fitting plane of the omnidirectional scanningarea according to the detection data (S120); determining the terrain parameters of the omnidirectional scanning area according to the fitting plane (S130); and adjusting the flight motion of the unmanned aerial vehicle according to the terrain parameters ( S140).

Description

technical field [0001] This description relates to the technical field of unmanned aerial vehicles, and in particular to a slope terrain prediction method, device, radar, unmanned aerial vehicle and operation control method. Background technique [0002] In some operation scenarios, drones need to fly over some uneven terrain, such as ground with slopes. For example, in the process of mountain operations, the UAV can detect the vertical distance relative to the ground directly below and maintain a certain height difference with the ground directly below, so as to realize ground-like flight such as terrain following. [0003] However, by detecting the height difference between the UAV and the ground directly below, and then adjusting the flight height, this method is a kind of post-feedback, and the response of terrain following is slow. Security poses a huge threat. Contents of the invention [0004] Based on this, this specification provides a slope terrain prediction m...
