A method, system and device for automatic and rapid selection of take-off and landing points for multi-rotor UAVs

Abstract

The present invention provides a method, system and equipment for automatically and quickly selecting the takeoff and landing point of a multi-rotor UAV, including calculating the pre-number of UAV patrol towers by obtaining the endurance time of the UAV, and determining the maximum number of UAV patrol towers. How many towers can fly far away; the effective working range of the drone is used to determine the number of towers that the drone can actually work effectively and the preset landing area of ​​the drone that the drone may land within the number of towers. The flight area of ​​the UAV and the preset landing area of ​​the UAV are placed in the three-dimensional map to conduct a visual analysis of the flight area of ​​the UAV at each point on the preset landing area of ​​the UAV, so as to obtain the UAV's flight area. The landing area can effectively avoid the decline of the pilot's control effect on the drone due to obstacles in the middle during the flight of the drone, and at the same time can choose a suitable location to land and recover the drone.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle navigation, and in particular relates to an automatic and rapid selection method, system and equipment for a takeoff and landing point of a multi-rotor unmanned aerial vehicle. Background technique [0002] After recent years of development, UAV technology has been widely used in line inspections in the power industry, and different types of UAVs have different inspection strategies. Due to the limitation of battery life, multi-rotor UAVs usually cannot complete the fine inspection of all towers along the entire line. In the actual operation process, it is necessary to formulate corresponding take-off and landing points for different sorties of UAVs. At present, the selection of take-off and landing points for multi-rotor UAVs mainly depends on the personal experience of the operators. The operators conduct an overall survey of the surrounding environment of the line towers and pas...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a method, system and equipment for automatically and quickly selecting the takeoff and landing point of a multi-rotor UAV, which are used to solve the problem of the large randomness of the selection of the takeoff and landing point of the UAV in the method adopted in the prior art. There are large uncertainties, and the process of selecting take-off and landing points takes a long time, resulting in the technical problem of low efficiency of drone inspections
