Abstract

This paper presents a recently developed Image Acquisition- Geometric Modelling system for the construction of geometric models of natural objects. This construction is achieved in a two-step procedure. First, the object of interest is digitised, i.e. points on the surface of the object are computed. Then, based on the digitised 3-D points, an approximating surface, a geometric model of the object of interest, is computed. Coupled with a mesh generation package, the system presented allows for further processing and analysis of the resulting model instead of the real object itself.
