Photogrammetry for Mobile Mapping: Bridging Degraded GPS/INS Performance in Urban Centers

摘要: This article on surveying and mapping innovations describes a system that uses photogrammetry to bridge the gaps in Global Positioning System/Inertial Navigation System (GPS/INS). The authors seek investigate using techniques support navigation during GPS signal outages. They propose fuse data with imagery by adjusting image measurements raw single adjustment step. solution is based INS stand-alone when signals are blocked. photogrammetric reconstruction outages investigated hybrid simulation. Images simulated imaging used. exposure stations contaminated errors. Results show accuracy distance dependent, while drift time dependent. process seems stable, researchers plan extend framework include pictorial from airborne mobile systems shapes rather than just point features.
