Mobile scanning system for the fast digitization of existing roadways and structures

Purpose - To present a Mobile Scanning System for digitizing three-dimensional (3D) models of real-world terrain. Design/methodology/approach - A combination of sensors (video, laser range, positioning, orientation) is placed on a mobile platform, which moves past the scene to be digitized. Data fusion from the sensors is performed to construct an accurate 3D model of the target environment. Findings - The developed system can acquire accurate models of real-world environments in real time, at resolutions suitable for a variety of tasks. Originality/value - Treating the individual subsystems of the mobile scanning system independently yields a robust system that can be easily reconfigured on the fly for a variety of scanning scenarios.
