New Survey Visualization: Merging Photogrammetric Textures into A Multi-beam Bathymetry 3D Map.
This is an abstract from the "Current Research and On Going Projects at the J Richard Steffy Ship Reconstruction Laboratory" session, at the 2019 annual meeting of the Society for Historical Archaeology.
Multi-beam survey provides accurate bathymetric information of seafloors. However, when multi-beam applications are used to map small-detailed areas, multi-beam data became exceedingly heavy, and its data processing takes several months. Photogrammetry provides high-resolution textures of targeted areas underwater. However, obstacle of this application is limitation of size of survey areas. It is not practical to use photogrammetry to capture areas larger than a hundred square mater. The authors experimented a new method to map and visualize seafloors; this new methodology provides ‘3D bathymetric data’ from multi-beam survey and ‘high resolution textures’ from photogrammetry. Consequently, this methodology provides a new type of visualization of seafloor, generated data of the methodology has general colored bathymetric data, beside targeted small areas can display diagnostic high-resolution textures on the surface. This methodology can be applied for deep-water mapping.
