摘　　要：基于Matlab强大的图像处理功能,首先对采集的车牌图像进行灰度化和去噪预处理,然后利用Sobel算子进行边缘检测,最后依据车牌字符对应的不同L值进行字符提取,得到了较为理想的视觉效果.Based on the powerful function of Matlab, firstly the collected image of vehicle license was grayed and denoised,then Sobel operator was used to process edge dection, at last the characters were picked up according to different L -value, and better visual effects were obtained.
