Inliers Ratio Promotion Algorithm Based on Global Topological Distribution of Image Matching Points
Aiming at the problem of image matching model estimation in the condition of high outliers ratio, an algorithm of inliers ratio promotion based on the global topological distribution of matching points is proposed. The algorithm can filter out some outliers only by the topological distribution characteristics of matching points and improve the inliers ratio, which can be applied to all the model estimation algorithms. First, matching types are divided into identical distribution and non-identical distribution based on the geometric topological distribution of inliers, and the matching model is given based on the two matching types. Second, the algorithm of inliers ratio promotion is given. Finally, series of interfaces are given to combine the proposed algorithm with the existing model estimation algorithm. In the experiment, some image matching model estimation algorithms are combined with the proposed algorithm. The experimental results show that the proposed method can significantly improve the inliers ratio and decrease the time consumption of the original model estimation algorithms after the combination with the proposed algorithm.
