Description
technical field [0001] The invention relates to a video monitoring system, in particular to a monitoring system combining infrared thermal imaging and visible light imaging. Background technique [0002] The current video surveillance system mainly uses visible light cameras combined with manual monitoring and video recording for daily security protection. However, it is difficult for visible light cameras to filter out interference and obtain useful video images under bad weather or low illumination conditions. Therefore, the preventive ability of the entire security system at night or in bad weather conditions is greatly reduced. In this case, infrared thermal imaging technology has been introduced into the security field with its advantages of long range, strong penetrating ability, and ability to identify hidden targets, and has become a part of the monitoring field. [0003] However, the resolution of the current infrared thermal imaging camera can only be up to about ...
