Automatic recognition of facility drawings and street maps utilizing the facility management database

Abstract

This paperproposes a new approachjor inputting handwritten Distribution Facility Drawings(DFD) and their maps into a computer automatically by using the Facility Management Database(FMD). Our recognition method makes use of external information for drawing/map recognition. It identijies each electric-pole symbol and support cable symbol on drawings simply by consulting the FMD. Other symbols such as transformers and electric wires can be placed on drawings automatically. When a contradiction is unsolved due to an inconsistency between the content of the DFD and the FMD, the system requests a manual feedback from the operator. Furthermore, it uses the distribution network ofthe DFD to recognize the street lines on the maps. This can drastically reduce the cost for computerizing drawings and maps.
