findHomography function

Mat findHomography(InputArray srcPoints, InputArray dstPoints, { int method = 0, double ransacReprojThreshold = 3, OutputArray? mask, int maxIters = 2000, double confidence = 0.995, })

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

Implementation

Mat findHomography(
  InputArray srcPoints,
  InputArray dstPoints, {
  int method = 0,
  double ransacReprojThreshold = 3,
  OutputArray? mask,
  int maxIters = 2000,
  double confidence = 0.995,
}) {
  mask ??= Mat.empty();
  final mat = Mat.empty();
  cvRun(
    () => ccalib3d.cv_findHomography(
      srcPoints.ref,
      dstPoints.ref,
      method,
      ransacReprojThreshold,
      mask!.ref,
      maxIters,
      confidence,
      mat.ptr,
      ffi.nullptr,
    ),
  );
  return mat;
