Abstract

3D reconstruction technique plays an important role in the applications for 3D data acquisition, such as medical diagnosis, animation and virtual reality. Moreover, the 3D triangulation process is one of the most important parts while reconstructing the smooth surface of a 3D object. The essential of 3D 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 3D point is an approximated value and makes the reconstructed surface uneven. In the paper, we proposed 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.
