Embodiment 1
[0083] Such as figure 1 As shown, the lidar-based intelligent security monitoring device includes a data communication module 100 , a lidar data analysis module 110 , an optoelectronic data analysis module 120 , a data fusion module 130 and an external device control interface 140 .
[0084] There are two data interfaces on the data communication module 100 , namely a lidar data interface 101 and an optoelectronic data interface 102 . The lidar data interface 101 is used to receive point cloud data collected by the lidar and send control signals to the lidar; the photoelectric data interface 102 is used to receive video data collected by the camera and send control signals to the camera.
[0085] The lidar data analysis module 110 is used to analyze and process the lidar point cloud data, and detect and analyze the targets contained therein, including a data processing submodule 111, a target detection submodule 112, a target tracking submodule 113, and a target analysis submo...
Embodiment 2
[0106] Such as figure 2 As shown, the intelligent security monitoring system includes a security monitoring device 200 , a lidar data analysis module 110 , a photoelectric data analysis module 120 , a photoelectric detection device 220 and a network switch 230 , which can be connected with an external device 240 .
[0107] Such as image 3 As shown, step 300 is executed, using the laser radar 210 and / or the photoelectric detection device 220 to collect information data around the monitoring point. Step 310 is executed to send the information data to the security monitoring device 200 . Step 320 is executed, the security monitoring device 200 converts and analyzes the information data of the lidar 210 , and processes the information data into dynamic grid data. Execute step 330, the security monitoring device 200 performs target detection, target segmentation and target tracking analysis on the moving grid data, determines whether there is a moving target in it, and analyzes...
Embodiment 3
[0109] In this embodiment, a lidar personnel monitoring system is proposed. Combining laser radar with traditional photoelectric equipment and integrating intelligent recognition algorithms to build an intelligent security monitoring system based on laser radar. The system can realize 360° global real-time monitoring all day long, and realize the functions of early warning, continuous tracking, abnormal behavior detection, and target recognition. Compared with traditional security systems, this system has the advantages of no target loss, false alarm rate and missed alarm low rate advantage.
[0110] The use of scanning three-dimensional laser radar for area detection can realize 360° all-round 24-hour real-time monitoring of the entire monitoring area;
[0111] Using the three-dimensional data of the laser radar, it can realize real-time tracking of all targets in the area, zero loss of non-occluded targets, and the rate of missed alarms and false alarms is much lower than t...
