Abstract: This paper used corner information as feature point in the front image of vehicle to recognize the type which the vehicle belongs to.We improved the Harris’ corner detection method and added the ratio of eigenvalues which represent different directions to the corner response,and thus the more corners were detected.Because the position of vehicle in video is changeable,the center of the license plate is defined as stable point,and vehicle type was recognized by the ratio of matching corner.The results of test verified the effectiveness of this method.

Key words: Harris corner,Corner detection,Vehicle type recognition,Corner response,Feature extraction
