Abstract: Ambiguous visual structures or repetitive textures of different scenarios would result in a large number of mismatching points in image matching stage, and false positive relative orientation is introduced which is locally consistent.In this paper, the probabilistic inference method is introduced and an improved detection algorithm of false positive relative orientations is presented. A Bayes network based on relative orientations between images is constructed using closed cycle constraints and priori probability models in Bayes network is derived and the maximum posterior probability in Bayesian network is solved using belief propagation algorithm. Experimental results show that using the proposed global consistency constraints method can effectively detect the false positive relative orientations and improve outcomes of scene reconstruction with high computational efficiency.

Key words: relative orientation, cycle constraint, maximum spanning tree, Bayes network, belief propagation
