Unmanned aerial vehicle obstacle avoidance control method and system thereof, and unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle obstacle avoidance control method and a system thereof, and an unmanned aerial vehicle and relates to the unmanned aerial vehicle control technology field. The method comprises the following steps of through a radar detection apparatus of the unmanned aerial vehicle, detecting obstacle information in an unmanned aerial vehicle flight environment; collecting current flight information of the unmanned aerial vehicle; according to the obstacle information and the current flight information, calculating an obstacle avoidance flight plan; and executing obstacle avoidance flight by the unmanned aerial vehicle according to the obstacle avoidance flight plan. In the invention, through the radar detection apparatus of the unmanned aerial vehicle, the radar detection apparatus can detect a flight speed and a flight direction of an obstacle in the unmanned aerial vehicle flight environment and can accurately determine a motion trend of the obstacle so that identification and avoidance capabilities of the unmanned aerial vehicle to the obstacle in an air route usage environment of a moving object are increased. Simultaneously, according to the obstacle information and the current flight information, the obstacle avoidance flight plan is calculated so that reliability and stability of unmanned aerial vehicle flight are increased.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle obstacle avoidance control method, system and unmanned aerial vehicle. Background technique [0002] With the advancement of technology, drones have gradually been widely used in commercial and civilian consumer markets, such as aerial photography, power line cruise inspection, news reports, wildlife protection and monitoring, environmental and natural disaster prevention and monitoring, and express delivery services; The real flight environment information of unmanned people is difficult to predict completely, and unknown sudden threats or obstacles are often encountered. At this time, the global route planned in advance cannot meet the requirements. In the actual application of drones, especially in the en-route use environment of moving objects, if the judgment of the movement trend of obstacles in the route is not accurate, it will cause...
