Target detection system and method based on laser barrier

Abstract

The invention discloses a target detection system and method based on a laser barrier. A scanning control module controls a laser transceiver structure to scan within a certain angle to form a laser barrier. The scanning angle information determines the standard barrier parameters; the laser detection module determines the shape parameters of the current laser barrier according to the laser ranging and scanning angle information in each scanning period, and compares them with the standard barrier parameters. When the robot is launched and invaded, the laser detection module outputs the angle range and distance information corresponding to the difference between the shape parameters of the standard barrier and the threshold value, which is used as the orientation information of the target found; Detection, especially to solve the problem of detection and discovery of ultra-low-altitude UAVs in complex urban environments.

Description

technical field [0001] The invention belongs to the fields of target detection, security and public safety, and relates to a target detection system, in particular to a laser barrier-based target detection system and method. 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 methods and products that can effectively det...
