Obtaining 3D Shape of Specular Surface Using Five Degrees of Freedom Camera System

Abstract

In this paper. a new method of obtaining specular surface shape by using five degrees of freedom camera system is described. The normal vectors of the surface are extracted by achieving the coincident condition between the camera axis and the surface normal vector. This method uses a five degrees of freedom (5DOF) camera to fulfill this task. From the normal vector data. the shape of the surface is reconstructed. The result shows that the methodology improves the 3-D shape of object measurement with good accuracy.
