摘　　要：为提高车牌定位的有效性和准确性,利用车牌的纹理特征,提出基于边缘检测和形态学运算相结合的车牌定位算法。在摄取车牌图像的过程中,会因为各种原因导致车牌图像有不同程度的倾斜变形,而倾斜的车牌很难被分割和识别,必须进行倾斜矫正,使用了基于Hough变换的倾斜矫正算法。实验结果表明该车牌定位算法和倾斜矫正算法快速有效。In order to improve the effectiveness and accuracy of the license plate location,this paper presents a method based on the combination between edge detection and morphological operations by license plate texture features. In the process of license plate image ingestion,license plate images could have different tilts and deformations to varying degrees which is difficult to be identified,so tilt correction must be carried out.This paper uses the tilt correction algorithm based on hough transform.
