Patent ID: 6993158

Claim:
An automatic moving object tracking device, comprising: a photographing unit photographing a monitoring area; a binary disturbance image generating unit generating a binary disturbance image signal from an input image signal of each frame acquired through the photographing unit; a moving object acquiring unit acquiring from the binary disturbance image signal information about a moving object by using a moving window as an initial tracking window having a predetermined size, and adjusting the initial tracking window in size so that the binary disturbance image signal contains the moving object therein; a moving object automatic tracking unit estimating information about a location in a following frame to which a center of the moving object is to be moved based on currently acquired information and previously acquired information about the center of the moving object, moving a center of the moving window to the estimated location where the center of the moving object is estimated to be moved to, and acquiring actual information about an actual center of the moving object in the moving window and the size of the tracking window; and a tracking status determining unit comparing the actual information about the moving object with the estimated information about the moving object, and determining a tracking status of the moving object based on a resultant error range of the actual information and the estimated information, the actual information about the moving object being acquired through the following frame.
