In order to solve the problems of general camera with unstable operation, poor reliability, low intelligence, small field of view, and poor all-weather working ability in the super wide temperature range field environment, a method of fusion, mosaic and recognition of multi-channel visible and infrared based on embed platform is proposed. The embed platform adopting the construction of ARM + FPGA, integrated in the detection and early warning camera, realizes the intelligent detection and recognition of threat targets in the fore-end of monitor systems, and validate its effectiveness. Results show that the camera has high integration and compact construction, and reducing pressure of video processing of the terminal monitor center.
