Detecting method for illegal parking car

A method for detecting an illegal parking vehicle is provided to detect a vehicle parked in an inhibited area by obtaining background images irrespective of condition variation such as variation of luminous intensity. A license plate of an illegal parking vehicle is recognized by scanning a park inhibited area and then a parked vehicle area is recognized. Next, background images are obtained by using an adaptive background model based on brightness of background(S1-S3). Non-moving pixels are set as detection background images in a real-time image pixel obtained on the park inhibited area and the detection background images are obtained(S4,S5). A difference image is obtained from the background images and the detection background images(S6). An illegal parking vehicle area is detected from the difference image(S7). A camera is operated based on the detected parked vehicle area information and the detected illegal parking vehicle area information, and then an image of the illegal parking vehicle is obtained(S9).
