Analysis of the Photogrammetry Use of Videos from 360-Degree Multicameras in Heritage-Related Scenes: Case of the Necropolis of Qubbet El-Hawa (Aswan, Egypt)

Abstract. This paper investigates the photogrammetric potential of 360-degree multi-cameras in complex heritage scenes, applied both indoors and outdoors at the Necropolis of Qubbet el-Hawa (Aswan, Egypt). While 360-degree cameras are increasingly used for heritage documentation due to their enhanced Field of View (FoV) and facilitated data acquisition, they still present limitations in geometric accuracy compared to techniques like Terrestrial Laser Scanning (TLS) or Close-Range Photogrammetry (CRP). Furthermore, indoor environments introduce additional challenges, particularly concerning illumination. These advantages and disadvantages are more pronounced when working with videos instead of still images: video acquisition significantly reduces time, but it often diminishes geometric quality due to lower resolution and exacerbated motion blur, especially in low-light conditions. The main objective of this study is to perform a methodological and feasibility analysis of capturing and photogrammetrically processing videos using 360-degree multi-cameras. We analyse the results across different scenes, focusing on evaluating the accuracy of the outputs. The proposed methodology aims to improve data acquisition efficiency by reducing or eliminating the need for Ground Control Points (GCPs) during the orientation process.
