Oetermining orientation of Laser scanned surfaces

Abstract

Real 3D data acquired from scanning technology provide interesting 3D models for research and industrial applications. However before these models can be used, a surface needs to be jitted to a point cloud of an unknown object, this process might create some undesirable properties, such as triangle normais pointing in incorrect directions. We present a robust algorithm that reliably fixes these triangle normal problems on nonmanifold, and self-interesting surfaces of scanned objects.
