抄録

We propose a new approach to understanding engineering drawings, which is the problem to recover the 3D data of the legal solid objects from the 2D data of a given three-view orthographic drawing. Our method essentially consists of two major processes: translation of the original 2D data to a constraint satisfaction problem (CSP) by using a constraint knowledge base, and solving the CSP to get the final 3D data by using a general CSP solver. To realize the translation process, we develop geometrical rules derived from the restoration knowledge based on the axiom of existence of 3D objects in the usual Euclidean space. Since a CSP, an intermediate expression of an original drawing, is actually a knowledge base independent from both the given 2D data and the final 3D data, our approach enables us (1) to tune up the knowledge base easily, (2) to customize the restoration system with high modularity, and (3) to make use of existing general purpose constraint solvers adopting many kinds of efficient search techniques as well.
