So this paper proposes a new method for automatic coarse registration of triangular meshes, which is used to approximately align the 3D measured data (represented in the form of triangular mesh) and the tessellated mesh of NURBS surface (instead of using NURBS surface itself to reduce computation) from larger initial pose difference.
