摘要

车牌定位在车牌识别中起着决定性的作用。为了提高去偏字符识别的精度，提出了一种基于RGB色彩空间和Hough变换的车牌校正定位算法。由于车牌是倾斜的，它可以定位去斜后的车牌。对于车牌不倾斜的，可以直接定位。车牌不倾斜定位精度为93%，倾斜定位精度为88%。

An improved license plate correction and localization algorithm based on RGB Hough

License plate localization plays a decisive role in license plate recognition.In order to improve the accuracy of character recognition by de-skewing,a license plate correction and location algorithm based on the RGB color space and Hough transform is proposed for the license plate of the blue background with white characters.It can locate the license plate after de-skewing for the license plate is inclined.For the license plate is not inclined,it can be located directly.The license plate localization accuracy is 93%for the license plate is not inclined,and it's 88%for the license plate is inclined.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
