Embodiment Construction
[0016] When the present invention is implemented, a camera system and a computer control system are installed in the piggery area of a large-scale pig farm. Frame module, motion analysis processing frame module, foreground fusion module, background update module, shadow detection module and foreground extraction module. The ground of the piggery area of a large-scale pig farm is a concrete floor, with some excrement left on it, and the background light of the entire video is bright. Perform adjacent symmetrical frame difference and background frame difference with parallel algorithm, perform foreground motion analysis according to the output variables of adjacent symmetrical frame difference and background frame difference, obtain state code, and use state code as control condition to perform parallel adaptive background update and The first two frames are differentially fused to obtain the foreground including the shadow, and the shadow detection module calculates the loc...
