OIS (Ocean Imaging Systems) Camera

Quick facts

  • - Wet weight/dry weight
  • Used alone on a xx cable or with towcam, multicore, rov, hov, auv etc
  • Depth rating
  • Provides 24MP (megapixel) Images
  • Downward facing camera, takes optimal images 4-5m from seafloor
  • (fov for typical uses (4-5m from seafloor)? Or is that too specific of a use case)
  • “Illuminators”?? (strobe, led)
  • How to power/charge
  • Capable of storing xx amnt of images
  • Easily communicates with a samsung tablet to change camera settings (f stop, iso etc)
  • Easily connects to a computer to download images/set internal clock
  • (does it have autofocus? Do we focus it? I should know this…i think focus is fixed for the set deployment depth?)
  • Optional scalars for determining image scaling

General description of OIS cam

The OIS (Ocean Imaging Systems) Digital Still Camera consists of a 24MP (megapixel) Nikon (D3300? D7100?) SLR camera inside a xxx m pressure rated housing. The OIS camera points directly downwards, and is capable of quiescent imaging - everything can be set up before deployment, requiring no further user input during dives. The OIS camera captures still images at regular time intervals, which can be adjusted to the user’s preferred timing. The OIS Camera’s F-stop and ISO are also programmable by the user before deployment. The photos are illuminated with either a 600W/S or 300W/S strobe that is set to trigger simultaneously as the photos are captured. The strobe is wired in conjunction with the OIS Camera through a power junction box (Jbox). The OIS camera is typically set to capture photographs every 10 seconds, since the strobe fuse recharge time is on average 7-8 seconds long. The photographs may also be illuminated further with a DSPL xxx lumen LED light.

The OIS camera has been used on the MISO Towcam system, MISO MC800 Multicores, HOV Alvin, ROV Jason, and more.
(highlight here the benefits of a system that does not require active user input)

General operations/capabilities/suggested settings

Talk about how it gets set up, deployed, etc, can change camera settings w/tablet,

Live data capabilities/topside setup
When used in conjunction with the WHOI SDSL Data-Link, which provides real-time telemetry, the OIS camera is capable of sending live images to the ship’s topside updating every 10 seconds.
Talk about the axis site, live still transmission w/datalink, etc

Data collection
Mention the usb/serial to computer capability, just use nikon software, etc (refer to dan’s guide)

Use cases
examples of how it has been used w/photos and maybe links to the towcam and multicore pages
