Virtual Experiencing and Pricing of Room Views Based on BIM and Oblique Photogrammetry

Procedia Engineering, 2017
Abstract Room views have influence on apartment prices. To assess such influence, a virtual experiencing and pricing method for room views based on building information model (BIM) and oblique photogrammetry is proposed. Firstly, using the photos collected by unmanned aerial vehicles (UAVs), a realistic 3D model of the surrounding environment of the ...
