Abstract
In this paper, we propose a recognition technique of electric poles and wires which are drawn on a power distribution facility map. The map represents power supply facilities. Proposed technique is based on circularity and connectivity, and consists of four phases. At first, we extract a power distribution facility area from input image using threshold value. Secondly, we apply a thinning. At the third step, we extract candidate poles based on circularity. Finally, after electric wires between two branch points is recognized based on connectivity, candidate poles with at least a wire are confirmed to electric poles.
