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)
