OpenCV CV::Mat and Eigen::Matrix

Question

Is there a reversible way to convert an OpenCV cv::Mat object to an Eigen::Matrix?

e.g., Some way of doing:

cv::Mat cvMat;
         


        

Answer 1

This works for me,

  #include 

  cv::Mat image;
  image = cv::imread("/dataset/images/15207_angle_image.jpg", CV_LOA D_IMAGE_GRAYSCALE);   // Read the file
  Eigen::Matrix eigen_mat;
  cv::cv2eigen(image, eigen_mat);
