Hello!
I'd like to transform an image using homography matrix.
That is, when I have an image taken at a certain position and attitude,
I want to get an image taken at a different position and attitude.
It is like a rectification, but I want to use homography matrix (which is obtained from information of translation and rotation) as the transform.
I have no idea of right OpenCV function to do that.
I tried warpPerspective(), but it produces awkward result. (1kb image)
Could you advise me to solve the problem?
My code goes like
Mat src = imread("tests/image3.jp2", IMREAD_COLOR);
Mat dst, M;
float H33[3][3];
//
//...calculate homography matrix H33
//
M = Mat(3, 3, CV_32F, H33);
warpPerspective(src, dst, M, Size(sideLength, sideLength));
imwrite("tests/image3_warp.jp2", dst);
