2020-05-28 15:48:11 -0600 | marked best answer | 'type' undeclared identifier opencv traits.hpp Hi all, I've got this error in the function: "calcOpticalFlowPyrLK". Basically I have to track a book from a video given, do I used SIFT features to detect the book in the video and surrounding it with a square obtaining the following result: Then I have to track (and show) the features of the book using the pyramid Lukas-Kanade tracker, and I'm using the following code: Where "prev_gray" is an empty Mat defined at the beginning of the code (before of the SIFT obj detection), "gray" is the first frame of the video converted in gray scale and keypoints_2 is the vector<keypoint> of the first frame of the video. At the execution of the method "calcOpticalFlowPyrLK(prev_gray, gray, keypoints_2, next_keypoints, status, err);", I'm getting the error "type: udeclared identifier (at traits.hpp)" and "type is not a member of 'cv::DataType<t>'" What could be the problem? Thank y'all! EDIT: Following break suggestion, I changed my code into: Using the KeyPoint::convert function to have the right type inside the calcOpticalFlowPyrLK(), but what I get in the "res" windows is just a blank space and I have no access to it (I can see the window, but I can't do anything on it). Is it a problem of my pc? Is it maybe not powerful enough for this? |
