Abstract

The invention discloses a method for generating a laser scanning barrier for UAV detection. According to the maximum flight height and maximum flight speed of the UAV and the size of the UAV perpendicular to the flight direction, the angular resolution of the laser scanning plane is set. rate and the time period of laser scanning, and then control the laser to scan 180 degrees in the laser scanning plane according to the time period through the scanner to form a laser barrier to detect drones, and there will be no laser barriers when drones invade As a standard barrier parameter, when the UAV invades, compare the current laser barrier parameters with the standard barrier parameters, and output the angle range and distance information corresponding to the difference between the standard barrier parameters and the threshold value, as the orientation information of the discovered target. Effective detection of human-machine intrusion can solve the problem of detection and discovery of ultra-low-altitude drones in complex urban environments.

Description

technical field [0001] The invention belongs to the technical fields of target detection, security and public safety, and relates to a laser scanning barrier, in particular to a method for generating a laser scanning barrier for unmanned aerial vehicle detection. Background technique [0002] Deliberate intrusion into sensitive areas mainly includes three types: personnel intrusion, drone intrusion, and robot delivery intrusion. For personnel intrusion, traditional methods mainly use detection methods such as video surveillance, infrared radiation, and optical fiber sensors, and many mature products have been formed. These traditional methods are likely to be effectively circumvented for relatively concealed drone intrusions and robot launch intrusions. In particular, the intrusion of UAVs is becoming more and more frequent, and the accurate detection of small and slow targets has quickly attracted the attention of many fields. Therefore, there is an urgent need for method...
