摘　　要：针对车辆牌照的自动识别问题,提出一种基于形态学的车牌识别系统设计。通过对采集到的原始彩色图像进行灰度化、滤波等预处理,并利用数学形态学方法对图像进行闭合、腐蚀等运算,进而实现了车牌定位,再使用投影法完成对车牌的字符分割,最后采用模板匹配法对字符进行识别。MATLAB仿真结果显示,设计具有较高的识别效果,识别速度较快。Aiming at the problem of automatic recognition of vehicle license plate,a design of vehicle license plate recognition system based on morphology is proposed.By preprocessing the collected original color image by graying,filtering,etc.,and using the mathematical morphology method to close and corrode the image,the license plate location is realized,and then the projection method is used to complete the pair.The character segmentation of the license plate is finally recognized by the template matching method.The simulation results of MATLAB show that the design has a higher recognition effect and the recognition speed is faster.
