Method for unmanned aerial vehicle to automatically carry out range finding, avoiding and crossing flight in three-dimensional space

Abstract

The invention provides a method for an unmanned aerial vehicle to automatically carry out range finding, avoiding and crossing flight in a three-dimensional space. In avoiding and crossing modes, spot hover is used to detect a barrier. Simultaneously, during crossing and avoiding processes, a plurality of range finding sensors on up and down, left and right, and front and back directions are used to detect, and comparison and analysis are performed on a self area and a volume, and then according to a type of the barrier, the crossing or the crossing mode is selected so that the barrier can be effectively avoided or passed through. Safe performance of the unmanned aerial vehicle during flying is greatly increased and the unmanned aerial vehicle can conveniently execute different instructions in various kinds of tough environments.

Description

technical field [0001] The invention relates to a method for an unmanned aerial vehicle to automatically measure distance, avoid and fly through in three-dimensional space. Background technique [0002] Existing drones use GPS to locate and fly. GPS signals are easily affected by clouds and buildings, so they cannot be positioned accurately, and they will also judge the wrong direction to control the flight. In addition, the operator can only see the status of the GPS plane map of the location of the drone when operating the drone, but cannot know the height of the object in front of the flight, and will not be able to judge whether the drone can fly over, so that it will collide with the drone. If it hits obstacles such as buildings, it will damage the wings or the fuselage, resulting in a crash or out-of-control flight, which will seriously injure people and property on the ground. Even if the UAV equipped with a camera borrows the camera to take pictures and transmits th...

AI Technical Summary

Problems solved by technology

[0003] UAVs that are limited to distance measurement in the horizontal direction can only avoid obstacles in the horizontal direction, and cannot achieve three-dimensional space distance measurement and avoidance, such as flying upwards and hitting the ceiling when taking off or falling to the ground too quickly when landing

The fundamental reason is the lack of ranging sensors, so that the drone cannot avoid and pass through obstacles, especially through spaces such as doors and windows, and cannot perform the next task at all.
