Aerial cable localization and management using a mobile mapping system

Aerial cables in urban area are complicated. On the other hand, to check interferences between heavy machines and road features, a safety and efficient 3D road environment survey system's necessity is increasing in the field of civil engineering. In this paper, efficient and robust aerial cable measurement method using a Mobile Mapping System (MMS) and its automatic extraction method from 3D point cloud model are introduced. And the MMS enables to measure the road 3D environment and reconstruct 3D environment efficiently. The MMS can acquire road environment data at the cruising speed. The MMS enables to detect aerial cables in excess of 6mm, and its detection ratio is 99.6%. The extracted aerial cable is registered to GIS and the result of registration to a GIS is introduced.
