Surface reconstruction in overlapping range images for generating close-surface 3-D object models

The paper addresses the problem of building close-surface (CS) models of 3-D objects by integrating multi-view range images of the object. For the purpose, we have to use overlapping regions between the images to register them into a common view-independent coordinate system. In this paper, we propose a method of removing redundancy in the registered multi-view data due to the image overlap. It is assumed that each image has been triangulated into a connected mesh after the image acquisition. We firstly remove triangle edges in the overlapping regions, and then reconstruct the regions by forcing both border lines to advance toward each other in an optimal retriangulation procedure
