SQUID-5 - Structure-from-Motion Quantitative Underwater Imaging Device

The SQUID-5, or a Structure-from-Motion (SfM) Quantitative Underwater Imaging Device with 5 cameras is a towed surface vehicle with an onboard Global Navigation Satellite System (GNSS) and 5 downward-looking cameras with overlapping views of the seafloor. This advanced underwater imaging system is specifically designed to allow the construction of high resolution (sub-centimeter) 3D models of the seafloor using SfM techniques. The 3D models resulting from that work are being used to support ongoing seafloor elevation change research being done under the Ecosystem Processes Impacting Coastal Change (EPIC) and Remote Sensing Coastal Change (RSCC) projects.
