A Surface Reconstruction Technique Based on 3-D Triangulation Enhancement

Abstract

3-D reconstruction technique plays an important role in the applications for 3-D data acquisition, such as medical diagnosis, animation and virtual reality. Moreover, the 3-D triangulation process is one of the most important parts while reconstructing the smooth surface of a 3D object. The essential of 3-D triangulation is to find the intersection of the rays emitting from the correlated points on each image pair, but the emitting rays always don't intersect with each other owing to the error in process. So the obtained 3-D point is an approximated value and makes the reconstructed surface uneven. In the paper, we propose an triangulation enhancement method, which reduces the perturbation in the reconstructed data and filter out the error caused by spurious vectors in the process of correlation.
