摘要
提出了一套基于Roberts算子和最大方差阈值算法的GUI车牌图像识别系统。针对相机或高清视频流所采集的照片,本文结合图片的预处理,采用梯度检测法进行边缘检测,基于像素点的先行后列的车牌定位方法,并用最大阈值方差法进行二值化处理,根据对二值边缘图像做积分Harr识别,把车牌信息从图像转化为文本输出。实验结果表明,该GUI系统能够正确实现识别车牌图像文本信息。
A GUI License Plate Recognition System which is based on the Roberts Operator and Maximum Variance Threshold Algorithm is put forward. This article aims at the photo from camera or HD video stream, combining with the image preprocessing, using gradient method for edge detection, after using the method of the license plate location that based on the first row and then column of pixels,with a maximum threshold variance binary, processing method according to the binary edge image Harr integral image recognition, based on the achieving the transformation from picture to text. The results of experiment shows that the GUI System can achieve the accurate text license plate.
