The source is based on MATLAB license plate recognition and voice broadcast. The system for the small family car blue and white license plate recognition. Approximate positioning of the blue color candidate area based on the ratio of RGB images. However, due to the RGB color space, the Euclidean distance between two points is not a linear scale and color distance, in the blue region of the positioning range setting is not well controlled. Therefore, the positioning error is the main cause. This appears in the picture under a blue background more recognition rate will drop, can not effectively extract the license plate area. This paper presents an adaptive adjustment program. On the segmented regions to identify adjustments. According to the aspect ratio, blue and white area than the candidate repeatedly positioning. Finally found the license plate area. After correctly identify the characters, prior to use for recording each character according to the corresponding sequence of characte
