3D Reconstruction of Underwater Structures

 
 

Lake Tahoe Barge Reconstruction

3D reconstruction techniques such as Structure from Motion are widely used in marine archaeology to document sites for remote analysis, but the underwater environment frequently poses challenges to 3D reconstruction. Issues such as a lack of robust landmarks and turbidity can result in poor-quality reconstructions. Additionally, the refractive effects of water can introduce geometric error into the computed models. This work aims to improve the capabilities of underwater reconstruction for marine archaeology applications.

Underwater Stereo Camera System

 Underwater Stereo Camera system developed for mapping underwater structures. The main pressure housing contains a stereo pair of IDS machine vision cameras, a Microstrain Inertial Measurement Unit, and a Sony QX100 camera. On the right side of the image is a Doppler Velocity Log used for acoustic bottom tracking.
