| Abstract(in English) | In the conventional method to estimate the planar surface parameters and the motion parameters with the assumption of feature points correspondence between input images, these parameters can be only estimated in case of optimized one motion and one plane parameters estimation problem. Therefore, in this paper, we proposed the estimation method for multiple motions and multiple planes as expansion to the conventional. However, this expansion causes the clustering problem that feature point is owned by incorrect plane, and the reliability of each plane is reduced. We assume that the observed noise model for the feature points is a two-dimensional Gaussian, and define the likelihood function with respect to this observed noise. Then, by using Gaussian mixture model, both the parameter estimation problem and the clustering problem can be formulated. To solve these problems, we apply the iterative computation method based on EM algorithm. The effectiveness of the proposed method can be confirmed by the computational simulation results. |
