Since remote times, mankind has been bound to water bodies and evidence of human life
from the very beginning hides under the water level, off the coasts, under shallow seas or …

Outside laboratory conditions and human-made structures, animals rarely encounter flat
surfaces. Instead, natural substrates are uneven surfaces with height variation that ranges …

This paper presents a survey on optical sensors and methods for 3D reconstruction in
underwater environments. The techniques to obtain range data have been listed and …

Current research on underwater 3D imaging methods is mainly addressing long range
applications like seafloor mapping or surveys of archeological sites and shipwrecks …

The underwater structured light vision system has the characteristics of a large amount of
information, high measurement accuracy, and good robustness, which has attracted the …

Two-thirds of the earth's surface is surrounded by water and the majority of it is still
unexplored. The underwater monitoring of the oceans and their surroundings is highly …

Archaeological excavations are often irreversibly destructive, so it is important to accompany
them with detailed documentation reflecting the accumulated knowledge of the excavation …

In some application fields, such as underwater archaeology or marine biology, there is the
need to collect three-dimensional, close-range data from objects that cannot be removed …

Underwater inspection, maintenance and repair (IMR) operations are being increasingly
robotized in order to reduce safety issues and costs. These robotic systems rely on vision …

Visual maps of the seafloor can provide objective information to characterize benthic
ecosystems and survey the distribution of mineral deposits on spatial scales that cannot be …
