Schematic diagram of field survey and underwater photogrammetry.
(a) Multi-camera system (MURAKUMO HANDY) used in photographing for underwater photogrammetry. One of four cameras is a spare one. (b) Camera trails estimated in photogrammetry processing in Metashape. Each pink, yellow, and cyan plot indicate the trail of each camera. Two orange circles show start and end points of photographing. Three orange squares indicate reference points for depth. (c) Flow diagram illustrating the creation of the 3D model through underwater photogrammetry.
