A fully interactive visualization method for building condition assessment

Abstract

The aim of the paper is to introduce a tool for the accurate assessment of the technical condition of buildings. The proposed methodology is becoming an efficient strategy for the massive inspection of building stocks, in big residential areas. The authors have developed an utility based on high-performance images captured by Unmanned Aerial Vehicles (UAVs). The flights of the UAVs have been technically protocolized in order to get the proper high-quality information about the real condition of the building. After collecting the images a 3D model is generated and orthophotos of building facades are created. The graphical information is connected with tables of attributes which allow the interactive georeferenced management and assessment. Main requirements and advantages of this visualization technique will be presented by analyzing a particular case study. The selected example will allow the illustration of the methodology. Ongoing developments and technical details about the information system and the analysis platform connected with the visualization tool will be also reported.
