Three Dimensional Surface Model from Laser Scanning of Proving Ground Road

Abstract Three Dimensional Surface Model from Laser Scanning of Proving Ground RoadAbstract: The paper aims at creating a 3D surface model of an existing road proving groundbuilt for vehicle testing. The road surface here has several different kinds of deviation featuresintended to test the vehicle for its stability and durability. An innovative laser scanning system,with two laser measurement sensors, has been designed and built for this purpose. The two laserscanners, scan in two mutually perpendicular planes XZ and YZ. This data is recorded andconverted to 3D point cloud data using the scan matching algorithm. The point cloud data thusobtained is processed with special algorithms to obtain the 3D model of the road surfacescanned. This precise 3D model of the road surface obtained can be used for virtual simulation ofthe vehicles’ performance.Keywords. three dimensional road model, road profile, laser measurement scanners
