摘　　要：根据车牌字符的排列规律和字符的几何特征,本文提出了一种基于第三字符定位的车牌字符分割方法。首先,该方法在车牌定位图像上定位出车牌的第三字符,再进行字符区域的分裂和合并,针对字符缺损情况,进行了字符区域扩展,而且对字符区域高度进行了调整,最终实现了车牌字符的精确分割。According to the rules of the characters of the vehicle license plate and the geometrical features of the charactersan approach for character segmentation of vehicle license plate is proposed which is based on the location of the third character.Firstlythe third character of the plate is located in the image of the plate location. And then the character regions will be divided and merged.And consequentlycharacter regions will be expanded for lack of a few character regions.Finallythe height of all character regions will be adjusted.As a result the characters of the plate are segmented accurately.
