Abstract

Accurate three-dimensional (3D) data from indoor spaces holds significant importance in various fields like real estate management, industrial archaeology and Cultural Heritage. Villa Maraffa complex, located near Ravenna (Italy), served as a case study for employing and comparing advanced technology and sensors in surveying these contexts. To acquire data, the sensors used were Matterport Pro 2 and Leica RTC360. The first one, mainly developed for real estate surveys, has been chosen because of the efficiency and cost-effectiveness in generating point clouds, albeit with lower precision compared to the Leica RTC360 Laser Scanner, the other sensor employed in this study. The focus of the paper is on assessing the point cloud s quality, with an analysis of the Matterport data, including global and specific evaluations. Potential issues like incomplete data and misalignment are identified by comparing coordinates from the Leica scanner. The results are examined to find an optimal solution for a prompt, precise, and well-timed survey, enabling a complete digital reconstruction of the object.
