Problems solved by technology

Although this method uses lidar and video for monitoring, it does not realize the linkage between lidar and photoelectric system, and does not really combine the two; although lidar is used to detect targets in sensitive areas, it does not Target specific analysis, such as target shape, speed, etc., so it is easy to introduce false alarms; although the target trajectory is recorded, there is no intelligent detection of the trajectory, and the suspicious behavior of the target cannot be automatically found; there is no tracking of the target, let alone the use of laser The gl...

Description

technical field [0001] The invention relates to the technical field of network monitoring, in particular to a lidar-based intelligent security monitoring device, method and system. Background technique [0002] With the development of society, security work has become an important task of the country and society, and the unattended intelligent security monitoring system has become the trend of the new generation of security monitoring system. Traditional security equipment is generally based on video surveillance, but the instantaneous monitoring scene of this type of system is small, and the false alarm rate and missed alarm rate are high under intelligent monitoring conditions. Peripheral monitoring of key areas and sensitive military checkpoints are basically based on traditional methods such as manual patrols. Therefore, the main function of the existing video surveillance system is to review afterwards. [0003] Traditional security monitoring systems mainly include p...
