A 3D model for building condition assessment

Abstract

The aim of the paper is to analyze practical aspects with use of 3D Model for accurate building condition assessment. Use of fully interactive visualization methods from a technical condition assessment platform going to be, especially taking into consideration current COVID-19 scenarios, a very supportive tool for the massive inspection of building stocks, particularly in big residential areas. The authors present the approach based on high-performance images that were captured by Unmanned Aerial Vehicles (UAVs). The next step is the generation of a 3D model and orthophotos of building facades. The graphical information together with tables of attributes will allow the interactive geo-referenced management and assessment, that is proposed as a form of interactive cooperation. The idea of this approach corresponds widely with the Building Information Modeling aims. The authors introduce the methodology, stages of the inventory and follow-up process carried out within the platform requirements together with advantages of the visualization techniques, basing on a particular case study. Technical details about the information system and the analysis connected with the visualization utility will be presented and illustrated.
