基于数学形态学和Hough变换的车牌定位算法
License plate location algorithm based on mathematical morphology and Hough transform
摘要
Abstract
To solve the problem of low locating rate with complex environment, a precise license plate locating algorithm is proposed based on mathematical morphology and Hough transforms. Firstly, color plate image is preprocessed. Seeondly, Top-hat transformation is used to highlight the license plates regions, and edge detection and connected component analysis are implemented on the image. Finally, Hough transform and the prior knowledge of license plate are applied to locate the plate precisely. The experimental results show that the algorithm has high robustness when image is in complicated background, and the accuracy is 97.3%, which meet the requirements of intelligent transportation systems about accuracy and real-time positioning of license plate location.关键词
