Abstract:
This contribution deals with the problem of converting paper drawings into computer-based representations suitable for further use in CAD and CIM applications. While previous approaches have been able to solve this problem for certain application domains, the kernel system presented in this paper is adaptable to a wide variety of applications including engineering drawings and electronic circuit diagrams. The key elements of our approach are a knowledge-based interpretation process and a declarative specification language for defining meaningful graphical objects to be recognized in a drawing. The potential efficiency problems of a strictly declarative approach are overcome by automatically compiling graphic specifications into efficient procedures. The adaptability and efficiency of the kernel system are demonstrated using examples from several domains.

The Thesis (written in German) summarizes all my research on drawing interpretation. It should provide you with a much better understanding of my work than the conference papers below. On the other hand you must be able to read German and you will need some time to go through the 200+ pages.

Abstract:
The paper presents a system, which enables the conversion of paper-based technical drawings into a format suitable for CAD systems. The system is based on a commercial available scanning and vectorization unit. Since the vectorization results are far from being perfect, a postprocessing component to remedy some of the weak points have been created. The improved vectorization results permit a knowledge-based interpretation of the drawing content along with error detection and drawing redesign.
