Paper Abstract

In this paper we present a new method for three-dimensional (3D) computerized modeling of geological objects from sets of intersected cross-sections. Geometric reconstruction from a set of topological and polygonal cross-sections is used in many cases of geological reconstruction now. However, most of current methods require that cross-sections must be parallel. Our method is based on sets of intersected cross-sections. With the help of cross-sections at another direction, this method can effectively solve the correspondence problem, matching components in adjacent sections. Besides, many complex geological phenomena can be reconstructed precisely, for example, stratum dying out position can be well defined in another directional sections. Last but not least, because sections at different directions are used to construct geological surfaces, model quality is greatly improved. The major steps and key algorithms in this method are all discussed in detail. A 3-D software platform has been developed based on this method. A case study in An Shan, Liao Ning Province, P.R. China shows that the method can be applied to practical and complex geological areas.
