Mismatching removal method and system and application

The invention belongs to the technical field of multi-view three-dimensional reconstruction, and discloses a mismatching removal method and system and application, and the mismatching removal method comprises the steps: carrying out the extraction and matching of feature points SIFT and SURF of a data set, and obtaining interior points through employing RANSAC; performing relative pose estimation by using an epipolar geometric mode; enabling the feature points to be subjected to triangulation to obtain two point cloud sets S and S , and calculating the distance d between every two corresponding points in the S and S ; carrying out region division on the point cloud S according to the positions of the three-dimensional points in the point cloud S ; adopting an AC-RANSAC adaptive threshold algorithm to modify parameters, and calculating a corresponding threshold t for the D; and filtering the three-dimensional points of the kth area according to the calculated threshold t.
