Implementation of a Real Estate Management System using Photogrammetry Method Allowing 3d Navigation of Buildings

Abstract

The objective of this study is to evaluate how the use of virtual representations of buildings, created through photogrammetry, can improve the efficiency and effectiveness of the real estate management system. In this regard, investigations have been conducted with stakeholders in the real estate sector, such as real estate agencies and tenants, to gather valuable information on real estate management. For illustration purposes, we have chosen to model the NASPW gymnasium. We have implemented a real estate management approach based on the photogrammetry method. To achieve our objective, we describe each step of the process, from the preparation of the photogrammetric mission (planning and simulating the mission) to data acquisition, carried out using a Phantom 4 Pro drone for aerial images and a Nikon D300 digital camera for interior shots. The data processing phase is also crucial, and it was done using the Agisoft Metashape software. We provide detailed explanations of the different steps in this process, which include image quality estimation, image alignment, georeferencing, dense point cloud generation, 3D mesh creation, and orthophoto generation.
