The invention provides an intelligent infrared thermal imaging and high-definition visible light dual-band video monitoring system, which is characterized in that it includes: a main control circuit unit, a high-definition visible light imaging unit, a thermal imaging unit, an HD-SDI high-definition video processing circuit, and an HD-SDI high-definition Video output interface, standard definition video switching processing circuit, standard definition video processing circuit, CVBS standard definition video output interface, control interface circuit and light intensity sensor processing circuit; the main control circuit unit is responsible for receiving instruction information from the control interface circuit or from the light intensity sensor processing circuit Receive the ambient light intensity signal, and control the high-definition visible light imaging unit to switch between high-definition visible light digital video and standard-definition visible light video, and control the standard-definition video switching processing circuit to switch between standard-definition visible light video and infrared thermal imaging standard-definition video. The invention can realize all-weather video monitoring, and provides visible light high-definition video monitoring function and infrared thermal imaging monitoring function.
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 ...
