UAV Automatic Collision Avoidance System

Abstract

The invention discloses an unmanned aerial vehicle automatic collision avoidance system, including an unmanned aerial vehicle situation sensing module used for single level or pixel level target detection, tracking and recognition and abstraction of global cognition of environment from information to realize cognition of environment; an unmanned aerial vehicle collision threat assessment and prediction module used for making a threat assessment and conflict prediction of static obstacles, extreme weather and moving targets in a detected area when an unmanned aerial vehicle runs in airspace; and an unmanned aerial vehicle decision collision avoidance module used for generating corresponding behavior selection after the unmanned aerial vehicle obtains a flight conflict trend through assessment prediction, planning a feasible optimal collision avoidance path in time through a flight path planner, and outputting an avoidance decision and a maneuvering instruction. The unmanned aerial vehicle automatic collision avoidance system can realize automatic sensing and avoidance during flight of the unmanned aerial vehicle in the air, realizes systemization, automation and intelligentization of unmanned aerial vehicle collision prevention, and remarkably improves flight safety of all aircrafts when the unmanned aerial vehicle and other aircrafts share airspace.

Description

technical field [0001] The invention relates to the field of air traffic intelligence, in particular to an automatic collision avoidance system for unmanned aerial vehicles. Background technique [0002] With the rapid development of aviation technology, the use of drones in the military and civilian fields continues to expand, and the flight range and running time of drones have doubled. It is an inevitable trend for drones to fly with manned aircraft. But at the same time, flight conflicts and safety issues between drones and manned aircraft are becoming increasingly prominent, and the automatic collision avoidance system of drones is the key to solving this problem. [0003] As the core component of the UAV system, the automatic collision avoidance system is directly related to the traffic safety and intelligence level of the UAV flight platform, and it is also one of the main challenges for the wider application of UAV systems. With the increasing number and types of dr...
