1994, published paper (DAS'94), 17 pages, English text
Abstract:
This paper is an attempt to further contribute to the current research on 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 this approach are a knowledge-based interpretation process and a declarative specification language for defining meaningful graphical objects to be recognized in a drawing. When solving real world recognition tasks the kernel system will have to deal with the problem of drawing tolerances. After an examination of part-aggregate relations, different kinds of tolerances will be discussed. Finally, a new method for handling structural distortions will be proposed and illustrated by an example from the domain of electronic circuit diagrams.

1992, published paper (MVA'92), 4 pages, English text
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.
1996, Dissertation am Fachbereich Informatik der Universität Hamburg, 220 pages, German text
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.
