The invention discloses a multi-channel video intelligent monitoring system based on a fish-eye lens. The multi-channel video intelligent monitoring system is characterized by comprising a fish-eye lens, a calibrated fish-eye vidicon, a high-speed digital signal processor (DSP) hardware system for real-time treatment of four channels of videos, and a fish-eye video intelligent analysis and treatment algorithm, wherein the calibrated fish-eye vidicon transmits a video signal in a monitoring area to the high-speed DSP hardware system through a cable; the high-speed DSP hardware system can process four channels of transmitted fish-eye video signals through the fish-eye video intelligent analysis and treatment algorithm in real time, carry out analysis and treatment on the input fish-eye video signals, detect out a movement target in each video and calculate the related parameter, then output the detection and calculation results, encode and store the videos. The multi-channel video intelligent monitoring system has the beneficial effects that seamless intelligent monitoring of a specific area is achieved on the premise of not adding the vidicon. Various kinds of alarm equipment are driven by oversized range monitoring, video real-time display, cycled storage, video intelligent analysis and treatment and detection result output. Thus, the monitoring safety performance is greatly improved, and meanwhile, the complexity of the system structure, the equipment procurement cost and the use cost are reduced.
