Quality assessment of 3D model generated from different image overlap / Sharoanas Shapiee

This research aims to examine the influence of various degrees of overlap on the accuracy of 3D models generated using close-range photogrammetry for documenting historical buildings. The accuracy of 3D models plays a pivotal role in the documentation and preservation of historical structures. Thus, comprehending the influence of overlap on the accuracy of 3D models is critical for producing high quality documentation of historical buildings using close-range photogrammetry. This study's objective is to assess the effect of different degrees of overlap on the accuracy of 3D models generated using close-range photogrammetry for documenting historical buildings. The authors conducted a study to investigate the impact of different degrees of overlap on the accuracy of 3D models. They utilized close-range photogrammetry to generate 3D models of a historical building with varying degrees of overlap. The accuracy of the resulting 3D models was evaluated using ground truth data. The research findings suggest that higher degrees of overlap lead to more accurate and high- quality 3D models. The optimal degree of overlap was identified to be 80% for achieving the desired level of accuracy. In conclusion, the study highlights the importance of higher degrees of overlap for producing accurate and high-quality 3D models of historical buildings using close-range photogrammetry. The paper provides critical insights into the significance of overlap and its implications for future applications of close-range photogrammetry in documenting and preserving historical buildings.
