| 摘 要： | 为了解决车牌倾斜对字符分割和字符识别带来的不利影响,文章基于Radon变换的思想,先利用Canny边缘检测器检测车牌边缘,再利用Radon变换搜索构成车牌矩形的直线段,并计算其倾斜角来校正倾斜车牌.测试结果表明该方法能准确地检测出图像的倾斜角,并取得良好的效果.

| Abstract: | This paper presents a method to remedy the negative effect arising from slant vehicle license plate's character and recognition based on Radon transformation and edge detection.First,use the image preprocessing adopted by the related operation of edge detection arithmetic operator.Then get the incline angle by the Radon transformation,and lossless rotation correction is performed to the tilt plate to the horizontal line.The testing results show that the tilt angle can be accurately obtained and the method i... |
