Unmanned aerial vehicle route dynamic adjustment and autonomous obstacle avoidance method and system

The invention discloses an unmanned aerial vehicle route dynamic adjustment and autonomous obstacle avoidance method and system, and particularly relates to unmanned aerial vehicle navigation monitoring, obtaining of a preset route before takeoff of an unmanned aerial vehicle, real-time monitoring of flight hidden dangers in the surrounding environment after takeoff, and judgment of whether autonomous obstacle avoidance needs to be triggered. After autonomous obstacle avoidance is triggered, the energy consumption of the unmanned aerial vehicle is evaluated and whether the route needs to be adjusted immediately is determined, if the route is not adjusted immediately, historical obstacle avoidance events and the remaining operation capability of the unmanned aerial vehicle are analyzed, the risk and maneuvering redundancy of a future route are evaluated, and after the risk and maneuvering redundancy of the future route are comprehensively analyzed, whether the route needs to be adjusted is judged again.
