In the process of hole-repairing in point clouds,it's difficult to repair by the indeterminate boundary of fragmentary area in the edge of point clouds.In view of this condition,the article advanced a method of fragmentary area repairing on the edge of point clouds based on image edge extraction and LS-SVM.After the registration of point clouds and corresponding image,the sub-pixel edge could be extracted from the image.Then it projected the training points and sub-pixel edge to the characteristic plane to confirm the bound and position for re-sampling.At last it got the equation of fragmentary area to accomplish the repairing by Least-Squares Support Vector Machines.The experimental results demonstrated that the method could guarantee accurate fine registration.
