Abstract
This paper concerns the problem of fast vehicle license plate location. A new method has been proposed for locating the vehicle license plate in the color image with a high speed. The color image is transformed into HSV color space and each single channel image is operated by different operations such as image equalization, image binary and so on. Then the results of each channel image is integrated, and a mathematical morphology method together with image smoothing, image filtering and contour extraction are used to get the candidate vehicle license plate. Finally, a minimum rectangle enclosing the extracted contour is obtained, and affine transformation is done to the rectangle. The experimental results of more than 140 images collected demonstrated that the accuracy of detection is 95.21%, and the average time cost for each image is about 50 milliseconds.
