Practical Applications of Underwater Laser Scanning in Maritime Archaeology Compared to Micro-bathymetry Sonar and Photogrammetry
Advances in multi-beam sonar have produced high density (and in the case of photogrammetry) textured, photo-realistic results of various underwater archaeological sites by rapidly capturing information in areas that are difficult or otherwise inaccessible to diving. In recent years, these technologies have been accompanied by underwater scanning, a method, which offers a step change in resolution, and consequently, significant interpretative potential.
However, each method has inherently different sources of uncertainty across various conditions where effectively gauging their performance remains elusive. This paper presents a new methodology for verifying accuracy through an easily deployable 3D scale and quantifies these technological differences while considering their implications of use within underwater archaeology. Future work, including the potential use of ROVs for deep water applications will also be discussed.
