3D modeling of underwater objects using photogrammetric techniques and software comparison

Abstract

Most of the earth is covered with water. Most of these waters are oceans. Despite the fact that so many areas are covered with water, research on underwater photogrammetry is not as numerous as above ground research. However, in recent years, with the integration of cameras underwater, researchers have turned to underwater photogrammetry studies. In this study, it presents research on whether the selection of SfM-based software is suitable for the underwater environment. In the research, data collection was carried out by placing an object in a 1.5-meter-deep pool. In the data processing part, Agisoft Photoscan, Context Capture and Reality Capture software were used and 3D point cloud data were obtained and evaluated from each software.
