Abstract

This paper presents a framework of a Surface Intrinsic Feature Based Method (SIFBM) and hence a SIF-based freeform surface characterization system is established, which attempts to address the deficiency and limitations of the traditional freeform surface characterization methods which are more susceptible to the present outliers and uncertainty due to the geometry complexity of the freeform surfaces. SIFBM is a generalized methodology which is independent of the types of freeform surfaces being characterized, and also free of the surface embedded frame. A prototype surface characterization system has been built based on the SIFBM and its capability has been successfully realized through a preliminary experiment.
