An algorithm applied to locate and draw characters from declining license plate is introduced. In regard to the characteristic of license plate's gray-scale , the license plate is located, then it is picked up from the background. With the method of Hough transform , the angle of the license plate's main line is calculated. After the license plate is rotated and the borderline is picked up, the characters are drawn exactly.It is more accurate and faster than the traditional methods.
