Abstract :
The problem in document analysis of the conversion of technical drawings into descriptions that are appropriate to be manipulated by CAD systems is addressed. Ideas are presented for the construction of 3-D-geometric models from noisy and inaccurate images of simple workpiece drawings. The main ideas are the search for instances of primitive solids in the image, the incremental construction of partial descriptions based on these primitives, and their manipulation to achieve consistency with the image data. The implementation of the method is described, limitations are discussed, and the possible future development of the approach is outlined
