AERO-TRIANGULATION AND PHOTOGRAMMETRY IN SENSIBLE INFRASTRUCTURES - HOW THE INDUSTRY BENEFITS FROM LOW-COST 3D MODELLING CONDUCTED BY UNMANNED AERIAL VEHICLES (UAV)

摘要

Given recent technological advances, small size UAV provide a suitable mean for accurate 3D modelling of sensible (maritime) infrastructures. Such models provide a valuable source of information in general port safety and security planning as well as emergency response operations. This aspect is particularly crucial as ports belong to a nation's critical infrastructure, where its multiple supply chains and hinterland connections are sensitive to disruptions of any kind. Dealing with a rising number of disrupting externalities and increasing occupancy rates, ports have a constant need for affordable technological innovations with regard to risk management. Based on practical experiments, this paper reveals the possibility of generating realistic 3D models on the example of port facilities. It further reveals that initial states of a 3D model can be generated in a short timeframe, providing a valuable quick-response information source for first responder in emergency scenarios.
