Design of object surveillance system based on enhanced fish eye lens

A new method is proposed for the object surveillance system based on the enhanced fish-eye lens and the high speed digital signal processor (DSP). The improved fish-eye lens images an ellipse picture on the charge-coupled device (CCD) surface, which increases both the utilization rate of the 4:3 rectangular CCD and the imaging resolution, and remains the view angle of 183 degree. The algorithm of auto-adapted renewal background subtraction (ARBS) is also explored to extract the object from the m
