Benefits and limits of underwater drones than aerial drones Drones underwater have both advantages and disadvantages. These drones can be used to capture stunning underwater footage but are very expensive and must be attached to a buoy.
The successor housing is no different, with all the usual Ikelite benefits at a competition-busting price: ABS-PC blend body, Dry Lock (DL) port system, and big control levers for the shutter release and AF-L button. Shoot with flash in manual mode out of the box, or add the D...
Target Users New underwater photographer wanting an easy point-and-shoot camera with growth potential. Advanced underwater photographer wanting a compact camera solution. Camera Feature Requirements Great to excellent image quality. A camera must be compact and lightweight when used topside. ...
In recent years, large improvements to underwater photographic lighting have been far and few between. ButDEMA 2019 seemed to bring a flood of cool new underwater lighting systems with substantial benefits. The YS-D3 was no exception. In fact, we can say with confidence than we think the S...

Each type has other environmental costs when compared to piled foundations (e.g. larger seabed footprint and associated impacts to the benthic habitat) which need to be balanced against any noise reduction benefits. Alternative piling methods are expected to reduce noise output but their feasibility...
This has two benefits. First, the photo-consistency check incorporated in the meshing process allows recovery of more high-frequency details visible in the images [42]. Second, the error budget propagation is theoretically achievable throughout the full photogrammetric workflow, from the BA downstream...
In order to simulate the AUV’s shooting effect, the camera was fixed to the rod to shoot around the target. As shown in Figure 6, the experimental equipment includes a camera with a lighting device, which is shown on the left, while the experimental environment is shown on the right, ...
