Video monitoring system with image fusion technology

The current information monitoring and warning system usually works by adopting one of the detectors such as the TV camera, low-light-level (LLL) TV and infrared thermal imager or switching among them. Every detector has its own advantages and disadvantages, which cannot fully reflect the needs of monitoring information when just using general models. In order to solve this problem, a video monitoring system with image fusion technology was designed. Through the analysis of the imaging mechanism and features of the three complementary detectors, the components of this video monitoring system were introduced. Based on the working principle of the system, the main structure of the front detection system was designed. The turntable achieves the field of view of +90~-30in vertical direction and 175in horizontal. The optical-axis parallelism error of the system is less than 0.5 mrad. After the discussion of the fusion algorithm and registration of images from different fields of view, the experiment of image fusion was done to test the performance of this system. Finally, image quality and system real-time testing show that the video image fusion monitoring system can realize all-day information monitoring.
