cv.decomposeHomographyMat

Decompose a homography matrix to rotation(s), translation(s) and plane normal(s)

[motions, nsols] = cv.decomposeHomographyMat(H, K)

Input

Output

This function extracts relative camera motion between two views observing a planar object from the homography H induced by the plane. The intrinsic camera matrix K must also be provided. The function may return up to four mathematical solution sets. At least two of the solutions may further be invalidated if point correspondences are available by applying positive depth constraint (all points must be in front of the camera). The decomposition method is described in detail in [Malis].
