DRIVING TYPE AUTO TRAFFIC ENFORCEMENT SYSTEM AND METHOD FOR MONITORING ILLEGAL STOPPING AND PARKING VEHICLES USING IMAGE STABILIZATION AND RESTORATION METHOD

摘要

The present invention relates to a driving type automatic traffic enforcement system and a method thereof which are able to: correct the shaking of an image due to the movement of an enforcement vehicle by using an image stabilization algorithm in the driving type illegal parking/stopping crackdown system; perform an accurate license plate number recognition by obtaining an image of clear image quality by using a focus degradation method; and efficiently crackdown on an illegally parking/stopping vehicle. The driving type automatic traffic enforcement system related to an embodiment of the present invention includes: an enforcement vehicle; a surveillance camera module which is installed in the enforcement vehicle; and a control unit which controls the surveillance camera module to photograph a surveillance image of an illegal parking/stopping area and detects a vehicle which is parked and stops in the illegal parking/stopping area by using the surveillance image. In a case where shaking is generated in the surveillance image which is photographed by the surveillance camera module by the driving of the enforcement vehicle, the control unit generates a correction image in which at least one part of the shaking is corrected by applying the image stabilization algorithm in the surveillance image and uses a first correction image which is at least one part of multiple images which form the correction image and a first restoration image which is obtained by applying the focus degradation method to the first correction image to recognize the letter of the license plate number of the vehicle.
