The invention provides an unmanned aerial vehicle detection and defense method and system, and the method comprises the steps: carrying out the feature extraction of an initial three-dimensional point cloud corresponding to a target application scene, so as to obtain a fused context feature, and generating an initial three-dimensional bounding box based on the initial three-dimensional point cloud, and performing three-dimensional transformation on the key points in the initial three-dimensional bounding box to obtain a three-dimensional attention area, performing fusion optimization on the three-dimensional attention area based on the fusion context features to obtain an optimized three-dimensional prediction box set, and positioning a target unmanned aerial vehicle in the target application scene based on the optimized three-dimensional prediction box set. And defending the target unmanned aerial vehicle based on the positioning result. According to the invention, the detection precision of the unmanned aerial vehicle can be improved, so that targeted defense of the unmanned aerial vehicle can be realized.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for detection and defense of unmanned aerial vehicles. Background technique [0002] In recent years, the price of consumer UAV products has been falling, the size is getting smaller and smaller, the performance is getting higher and higher, and the control is getting easier and simpler, and the UAV is rapidly developing from the military field to the commercial field. While drones bring joy and convenience to people, they also bring security and privacy issues. This will enable technologies to monitor and identify drones and keep them away from sensitive areas. There are more and more accidents related to drones. For example, illegal aerial photography of drones in no-fly zones causes leaks, drones "fly in the dark" near airports causing flight accidents, and drones are parked arbitrarily to obstruct public transportation. Drone crashes cau...
