Description: 一种车牌图像校正新方法
【摘要】因摄像机角度而造成的机动车牌图像倾斜会对其后继的字符分割与识别带来不利的影响。本文在分析了车牌倾斜模式的基础上,提出了一种基于最小二乘支持向量机（LS-SVM）的车牌图像倾斜校正新方法。通过LS-SVM线性回归算法求取坐标变换矩阵并对畸变图像进行旋转校正。主要方法：首先,将二值倾斜车牌图像中的像素转换为二维坐标样本,并构造图像数据集 再通过LS-SVM线性回归算法对该数据集进行回归,求取主要参数 最后,再由该参数转换为能反映图像倾斜方向的2维坐标变换矩阵。实验结果表明,该方法简便实用,对光照、污迹等不敏感,抗干扰能力强。-New Method of a license plate image correction
Abstract caused due to camera angles, the image tilt motor vehicle license will have on its subsequent recognition of characters segmentation and adverse effects. Based on the analysis of the inclined plate model based on proposed based on least squares support vector machine (LS-SVM) of the license plate Skew new approach. By LS-SVM linear regression algorithm to strike a coordinate transformation matrix and rotate the image distortion correction. Main methods: First, the value of the two inclined plate in the image pixel is converted to two-dimensional coordinates of the sample, and construct the image data sets then the linear regression through the LS-SVM regression algorithm for the data set to strike a key parameter final , and then by the parameter is converted to reflect the tilt direction of two-dimensional image coordinate transformation matrix. The experimental results show that the method is simple and practical, to light, Platform: |

Description: 本程序采用一种基于垂直Sobel算子检测边缘和投影法的车牌定位方法,根据车牌区域竖直纹理突出的特点，利用Sobel垂直算子提取边缘，然后投影得到车牌的水平投影图，利用水平投影图分割出车牌，再运用膨胀运算进行车牌垂直定位。利用旋转投影法寻找车牌倾斜角度，然后用双线性插值进行车牌图像倾斜矫正。对经过精定位的车牌利用垂直投影法，找出各个字符的中心点，根据字符中心点位置进行切割。同时将切割出来的图片与数据库中的每张模板图片进行减法运算，计算该图片与模板的均方误差，其均方误差最小的模板即为识别出的字符。-This program uses edge detection and projection of license plate positioning method based on vertical Sobel operator, according to a prominent feature of the license plate area vertical texture operator Sobel vertical edge extraction, then the horizontal projection of the projector to get the license plate, the horizontal projection the Figure split out the license plate, and then use the the dilation operation license plate vertical positioning. Take advantage of the rotation projection method to find the license plate tilt angle, and then the license plate image tilt correction bilinear interpolation. The focal point for fine positioning license plate using the vertical projection method to identify each character, according to the the character center point cut. Cutting out pictures with each template images in the database, subtraction, calculation of the mean square error of the picture with the template, the mean square error of the smallest template is identified characters.
