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...
This paper describes a precision positioning technique that can be applied to vehicles in urban areas. The proposed technique mitigates Global Positioning System (GPS) multipath by means of an omnidirectional infrared (IR) camera that can eliminate the need for invisible satellites [a satellite detected by the receiver but without line of sight (LOS)] by using IR images. Some simple GPS multipath...

In the near future, precise digital map data is said to be applied to the next generation car navigation system as well as ITS to increase the driving safety. It is important to maintain digital map data's freshness and accuracy. A MMS (Mobile Mapping System) can acquire this highway database, while offering unbeatable productivity with the combination of navigation and videogrammetry tools. The proposed...
