摘要：In recent years, public and private organizations worldwide are facing a continuously increasing demand to build and maintain the asset inventory of their infrastructure network. This is due to standing legislature or is associated with operations relative to maintenance, procurement, traffic, valuation or safety and emergency response issues. In response to this urgency, today's technology allows the integration of various sensors that enable efficient products for mobile mapping solutions. Geo-3D is a leading provider of geomatics and GIS data acquisition hardware and software solutions, who works closely with clients and academia to optimize products and solutions. The Trident-3D solution is a georeferenced land videography system that utilizes the latest generation of positioning sensors (GPS, INS, DMI), high-resolution digital cameras, laser scanners and photogrammetry to create an advanced tool for large-scale data collection and asset management. The most recent developments of the system are automated road sign detection and transverse slope determination. Future developments will include pavement markings in the automated process. In this paper, Trident-3D technology and its advanced features are presented and discussed in the frame of collaboration with the National Technical University of Athens (NTUA), Greece
