OpenCV创建矩阵以及转为Eigen矩阵

1.opencv创建矩阵

例

代码

cv::Mat cameraMatrix = (cv::Mat_<double>(3, 3) << 1106.260000000000, 0.000000, 959.196000000000,
                        0.000000, 1106.130000000000, 639.281000000000,
                        0, 0, 1);
cv::Mat distCoeffs = (cv::Mat_<double>(1, 8) << 9.723910000000, 5.235030000000, -0.000011897200, -0.000105859000, 0.236858000000, 10.137300000000, 9.097570000000, 1.397940000000);

2.opencv矩阵转eigen——cv2eigen

例

代码

cv::Mat cameraMatrix = (cv::Mat_<double>(3, 3) << 1106.260000000000, 0.000000, 959.196000000000,
                        0.000000, 1106.130000000000, 639.281000000000,
                        0, 0, 1);

Eigen::Matrix<double, 3, 3> eigen_cameraMatrix;
cv::cv2eigen(cameraMatrix, eigen_cameraMatrix);
