findHomographyAsync function

Future<(Mat, Mat)> findHomographyAsync(
  1. InputArray srcPoints,
  2. InputArray dstPoints, {
  3. int method = 0,
  4. double ransacReprojThreshold = 3,
  5. OutputArray? mask,
  6. int maxIters = 2000,
  7. double confidence = 0.995,
})

FindHomography finds an optimal homography matrix using 4 or more point pairs (as opposed to GetPerspectiveTransform, which uses exactly 4)
