In the field of wide-area video surveillance in forest fire prevention, border defense, coastal defense, ports, oil fields, etc., long-distance and ultra-long-distance video surveillance
The application of control products is becoming more and more extensive. Both integrated laser and thermal imaging observation cameras, with fog-passing function, can also be used at night
With the aid of auxiliary laser for target detection, the image information has both spatial resolution and time resolution capabilities; it has both the information of the detected object and the spatial environment of the scene; it contains both the static information of the observation target and the dynamic movement of the observation target
State information.
Based on the lidar scanner XD-TOF series positioning, the video linkage system uses the computer system software to link the target space/geographic data acquired by the radar with the rotation angle of the long-distance photoelectric turntable/wide-area surveillance camera and the lens focal length to achieve Real-time review of the scene images of the space and geographic location. The system consists of positioning radar, long-distance photoelectric turntable/wide area surveillance camera, server, system software installed on the server, transmission system, etc.
The lidar XD-TOF series adopts mature products and has a SDK package for secondary development. The secondary development and integration of the software can realize video linkage monitoring of radar detection targets. Compared with the conventional long-distance monitoring system, the lidar and video linkage system has the following advantages: first, the target detection speed is fast; second, it can detect multiple targets at the same time; third, it is less affected by meteorological conditions, and the detection accuracy is high; fourth, the system is completely Realize digitalization, networking, intelligence and informationization.
The main functions of the system are: detection and monitoring of targets (people, cars, ships) within the range of 25/30/50m; continuous detection day and night; tracking of designated target movements; target map marking.
