Abstract

This paper describes a proof-of-concept computer system capable of interpreting graphical component connectivity in Process and Instrumentation Drawings (P&IDs). The input drawing is a CAD file in DXF format. Drawing features are considered to be pipes or symbolic entities with geometrically constrained attachment ports. A low-level image processing front-end is currently being developed to support the interpretation of drawings in vector format from scanned paper P&IDs. A hierarchical data structure is used to enable recognition of components in collinear and circuit complexes.
