An aquascope (also called bathyscope) is an underwater viewing device. It is used to view the underwater world often from dry land or a boat. It eliminates the water surface glare and allows viewing as far as water clarity and light permit. The underwater viewer can be used for observing reefs, checking boat moorings, secchi disks and other ...
Passive system underwater cameras let lifeguards inspect multiple underwater views simultaneously from a single location. [ 6 ] [ 7 ] Cameras can cover areas which may otherwise be obstructed. Below water cameras can be paired with above water cameras to provide face-to-body matching if there is an incident where a swimmer needs to be ...
Underwater computer vision is a subfield of computer vision. In recent years, with the development of underwater vehicles ( ROV, AUV, gliders), the need to be able to record and process huge amounts of information has become increasingly important. Applications range from inspection of underwater structures for the offshore industry to the ...
ROV at work in an underwater oil and gas field. The ROV is using a torque wrench to adjust a valve on a subsea structure.. A remotely operated underwater vehicle (ROUV) [citation needed] or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general ...
A Nikonos V amphibious camera Underwater housing for SLR with dome port, arms and lights. Some cameras are made for use underwater, including modern waterproof digital cameras. The first amphibious camera was the Calypso, reintroduced as the Nikonos in 1963. The Nikonos range was designed specifically for use underwater.
The original Argo, used to find Titanic, was 15 feet (4.6 m)long, 3.5 feet (1.1 m) tall, and 3.5 feet (1.1 m) wide and weighed about 4,000 pounds (1,800 kg) in air. It had an array of cameras looking forward and down, as well as strobes and incandescent lighting to illuminate the ocean floor. It could acquire wide-angle film and television ...
Baited remote underwater video (BRUV) is a system used in marine biology research. By attracting fish into the field of view of a remotely controlled camera, the technique records fish diversity, abundance and behaviour of species. Sites are sampled by video recording the region surrounding a baited canister which is lowered to the bottom.
Assembly and disassembly underwater are not possible without flooding the camera. There are three basic components to the camera: the internal mechanism, an outer shell, and the interchangeable lens. The camera body consists of two black enameled cast alloy parts; one piece carries all the camera parts (winder, shutter, and viewfinder), which is lowered into the o
