Fire passage occupation recognition system and method under laser and radar cooperation

Abstract

This application provides a fire lane occupancy identification system and method using laser and radar collaboration, relating to the field of laser radar technology. The system includes: a point cloud generation module, used to emit laser beams to the target area using a solid-state laser radar, receive reflected signals, extract time difference and phase difference, convert them into polar coordinate data, and generate a point cloud dataset; a 3D spatial model construction module, used to perform point cloud filtering, clustering, and 3D reconstruction based on the point cloud dataset to construct a 3D spatial model of the target area; and an occupancy decision module, used to calculate the space occupancy rate based on the 3D spatial model, and when the detected space occupancy rate exceeds a preset dynamic threshold, to perform adaptive occupancy decision and push alarm information. This application can solve the technical problem of low occupancy detection accuracy in existing technologies, achieving the technical effects of improving detection stability, reducing false alarm rate, and enhancing system adaptability and linkage response capabilities.
