THE COMPACT UNDERWATER STEREOSCOPIC VIDEO CAMERA
This compact 3D camera has been specially designed for use on Underwater Remotely Operated Vehicles (ROVs) as used in the offshore oil and gas industry. The camera contains two lenses mounted side-by-side to simulate the two human eyes, and allows the capture of stereoscopic 3D video footage for presentation in 3D to a human operator. The cameras have been used in a range of field operations and have performed extremely well.

Stereoscopic video provides many advantages over regular 2D video. Improved image understanding, improved ability to see through suspended matter or turbid water, improved ability to see through visual clutter, and an improved ability to judge size and distance. For ROVs that are fitted with a manipulator arm, stereoscopic video also improves teleoperation performance - reducing task times and reducing the risk of damage. Low resolution photogrammetry is also possible.
Good feedback has been received from field-usage of CMST's stereoscopic video systems: "ROV operators really felt the system was the answer to increasingly difficult/complex manipulator tasks."
The Compact Underwater Stereoscopic Video Camera can be used with a range of different commercially available stereoscopic 3D displays.
