Comparative Analysis of Structure-From-Motion Underwater Point Cloud Processing Techniques for a Steep Mountain Creek

Mapping underwater topography in mountain creeks with autonomous aerial vehicles and structure from motion photogrammetry is challenging due to steep slopes, rough substrates, and complex refraction effects. This study investigates which bathymetric correction method&#x2014;<italic>Simple</italic> o...
