The homography between captured images of a planar object is determined and decomposed into at least one possible solution, and typically at least two ambiguous solutions. The removal of the ambiguity between the two solutions, or validation of a single solution, is performed using a viewing angle range. The viewing angle range may be used by comparing the viewing angle range to the orientation of each solution as derived from the rotation matrix resulting from the homography decomposition. Any solution with an orientation outside the viewing angle range may be eliminated as a solution. |
