Research on Surface Reconstruction from Intersecting Curves

Abstract:

This paper comes up with an stereo matching method for handy-scanner based on cross light. The handy-scan system with two cameras and one cross laser beam can scan very detail accurately through cross laser. 3D information is gained by dealing with cross laser image. What we do aims at estimating the transformation of the measured objects under the world coordinate. In order to achieve this goal, firstly we use 8-points algorithm to compute fundamental matrix. Then, the points on the left and the right can be matched based on fundamental matrix. The 3D coordinates of the point on the cross laser can be obtained by triangulation and curve surface differential. The experiment proves that this algorithm solves the problem of calculating the matching points in disorder. And in some way, it increases efficiency of matching cross laser stripes.
