Abstract :
An automatic maps and drawing recognition method in which recognition processes are executed in parallel is described. First, the image is divided up according to its particular features, then each layer of candidate elements is recognized under the paralleled processing environment composed of automatic recognition, and man-machine oriented semi-automatic recognition, and finally the relationships between separate elements are settled using a rule-based matching process. This method is applied to the system for constructing electric power distribution databases. This system achieves a higher processing speed with better recognition precision than conventional systems
