Abstract

The AUTORED system is a computer-based system for automatic reading of electronic circuit diagrams, which was developed several years ago. This paper presents some of our new results in AUTORED research. The design of AUTORED consists of two major components: automatic interpretation of electronic diagrams, and organization of interpretation results into a knowledge base for CAD applications. An electronic circuit diagram may be segmented into three parts which are the graphical functional symbols, the connection line segments, and the denotations. New techniques for extracting symbols and denotations from the circuit diagram are presented in this paper. These techniques are designed for junction and corner extraction, line segment tracing and linking, line segment classification, connection-line segment removal and blocking, symbol locating and denotation character grouping. A knowledge base is developed to facilitate the tracing, template-matching, and categorization processes.
