Abstract: Subsidence and geometry deformation monitoring are essential for safe transportation on a high-speed railway. Terrestrial laser scanning (TLS) is able to collect dense three-dimensional point data from the survey scene and ...

Abstract: Indoor high-precision maps are necessary for many applications, including robot navigation and location-based services. Raw indoor map boundaries are too irregular and coarse to be used in practical applications directly; ...

Abstract: AbstractDue to the underground or enclosed nature of subway systems, satellite navigation signals are often difficult to receive. Without reliable signals, mobile measurement systems are prone to significant positioning ...
