Patent ID: 8294768

Claim:
A motion detection system comprising: a processing unit; and a storage system connected to the processing unit and storing a plurality of modules to be executed by the processing unit, wherein the plurality of modules comprises: an image analyzing module to obtain characteristic values of a plurality of images of a scene captured by a pan-tilt-zoom (PTZ) camera; a storing module to store the characteristic values of the plurality of images; an image matching module to perform a fuzzy matching of two consecutive images of the plurality of images according to characteristic values of the two consecutive images, to obtain a corresponding area in both of the two consecutive images wherein the corresponding area in both the two consecutive images has a correlation degree of an autocorrelation of the characteristic values of the two consecutive images, the correlation degree is greater than a predetermined value; a tracking module to determine a motion area with different characteristic values of the corresponding area in the two consecutive images, and obtaining position information of the motion area in the scene; and a drive module to receive the position information of the motion area, and adjust parameters of the PTZ camera, allowing the PTZ camera to shoot the motion area.
