Description: 在opencv上实现双目测距主要步骤是：
1.双目校正和标定，获得摄像头的参数矩阵：
进行标定得出俩摄像头的参数矩阵
cvStereoRectify 执行双目校正
initUndistortRectifyMap 分别生成两个图像校正所需的像素映射矩阵
cvremap 分别对两个图像进行校正
2.立体匹配，获得视差图：
stereoBM生成视差图
预处理： 图像归一化，减少亮度差别，增强纹理
匹配过程： 滑动sad窗口，沿着水平线进行匹配搜索，由于校正后左右图片平行，左图的特征可以在右图对应行找到最佳匹配
再过滤： 去除坏的匹配点 通过uniquenessratio
输出视差图disparity：如果左右匹配点比较稠密，匹配点多，得到的图像与原图相似度比较大， 如果匹配点比较稀疏，得到的点与原图 相似度比较小
3.得出测距：
把生成的视差图输入 reprojectImageTo3D（）函数，生成3D点云，3D点云中保存有2D图像的三维坐标，再读出每帧图像的三维坐标中的z轴的值，就得出了距离数据。(Binocular distance measurement implemented on OpenCV)

Description: 算法思想来自于网上资源，先使用图像边缘和车牌颜色定位车牌，再识别字符。车牌定位在predict方法中，为说明清楚，完成代码和测试后，加了很多注释，请参看源码。车牌字符识别也在predict方法中，请参看源码中的注释，需要说明的是，车牌字符识别使用的算法是opencv的SVM， opencv的SVM使用代码来自于opencv附带的sample，StatModel类和SVM类都是sample中的代码。SVM训练使用的训练样本来自于github上的EasyPR的c++版本。由于训练样本有限，你测试时会发现，车牌字符识别，可能存在误差，尤其是第一个中文字符出现的误差概率较大。(Bits in the predict method, for clarity, add a lot of comments after completing the code and testing, see the source code. License plate character recognition is also included in the predict method. Please refer to the comments in the source code. It needs to be noted that the algorithm used for license plate character recognition is SVM of opencv. The training sample used for SVM training comes from the c++ version of EasyPR on github. Due to limited training samples, you may find errors in license plate character recognition when testing, especially the error probability of the first Chinese character is large.)
