Leftover object detection device, method and system

摘要

An abandoned object detection apparatus and method and a system where the apparatus is configured to match each pixel of an acquired current frame with its background model, mark unmatched pixels, taken as foreground pixels, on a foreground mask, add 1 to a foreground counter to which each foreground pixel corresponds, and update the background model; for each foreground pixel, mark a point corresponding to the foreground pixel on an abandon mask when a value of the foreground counter to which the foreground pixel corresponds is greater than a second threshold value; and for each point on the abandon mask, process the abandon mask according to its background model and buffer background or foreground mask. Hence, when the abandoned object leaves and how long it stays may be judged, and interference of occlusion and ghost may also be avoided, thereby solving a problem of illegal road occupation identification.
