抄録

A blur correction method of license plate images on running vehicles taken with traffic monitoring cameras is proposed. Since the exposure time of the traffic monitoring cameras is generally 1/30-1/60 s, the taken images are degraded by the motion blur of running vehicles. In the proposed method, the parameters of the motion blur are estimated from a taken image sequence, and then the motion blur is corrected with Wiener filter. The images which are restored by the proposed method demonstrate the efficacy of the proposed method.
