概要

論文の詳細を見る
An intelligent translating system is being developed, which extracts the CAD data from mechanical drawings. The system consists of three modules, image processing, image recognition and image understanding. On the basis of local structure of drawing, image recognition module tries to identify visible lines, dimension lines, extension lines, broken lines and center lines. In image understanding module, vector data is modeled on the molecular coupling. Feature points and vectors are regarded as atoms and molecules respectively and the certainty of understanding is denoted by the molecular force. The drawing is expressed by the hierarchy of the object oriented representation, wcich is composed of nodes, segments of lines and front, side and top views. Expert rules are applied to detect and correct the erroneous result of recognition and complete the understanding.
