Mobile mapping

摘要

3D Laser Mapping has added new technology to its StreetMapper device. The vehicle-based laser mapping system is now being offered with a range of tools for the automatic calculation of bridge heights and other measurements. StreetMapper Bridges automates processing of 3D laser scanned measurements using statistical algorithms to identify road surfaces, isolate bridge data, identify lane markings and remove noise. The application then extracts cross sections from the data and calculates clearances and other user-defined measurements. This automation is said to enable large-scale use of laser mapping by eliminating manual inefficiencies and reducing the chance for error.
