| Abstract(in English) | This paper presents the mechanism of solution ambiguity problem in estimating 3D motion parameters by homography decomposition. We found that solution ambiguity is not inevitable. It depends on two kinds of factors: (1) when the object size is fixed, it depends on changing the 3D motion parameters; (2) when the 3D motion parameters are fixed, it depends on changing the size of the object. Meanwhile a new improved method using two planes' constraint to resolve the solution ambiguity problem from only two pieces of images by homography decomposition is proposed in this paper. The correctness and effectiveness of our proposed theories are proofed by simulation experiments which is basing on a huge database. |
