Underwater Volcano documented with the Adimec 2 Megapixel Color Machine Vision Camera

Posted by Gretchen Alper on Thu, Jan 10, 2013

With their excellent image quality and robust design, machine vision cameras find homes in some unique and demanding applications beyond manufacturing and measurement instruments.

Adimec is proud to have worked with the Advanced Imaging and Visualization Laboratory Woods Hole Oceanographic Institution (WHOI) (www.whoi.edu) for many years. The Advanced Imaging and Visualization Laboratory, AIVL, have implemented Adimec HD color cameras into a variety of their imaging systems, including an underwater, stereoscopic 3-D system that collected video in the NASA Neutral Buoyancy Laboratory (NBL) showing astronauts practicing repairs in a simulated weightless experience for a 3D IMAX movie.

Another impressive example is the NSF’s National Deep Submergence Facility at WHOI Footage that was taken on 2 different expeditions to an underwater volcano in the Pacific Rim. Filming was done more than 1,500 meters deep, and the HDTV camera system was on WHOI’s remotely operated vehicle, Jason.

Jason was able to get extremely close to the volcano and Images were captures of the volcano erupting underwater. This was the first time a deep-sea volcanic eruption was documented. Several animals including an uncommon type of shrimp were observed. See video images:

When designing the imaging system, The Advanced Imaging and Visualization Laboratory, AIVL, at WHOI was looking for a sensor where they could get simultaneous high quality stills and motion imagery. They also wanted something that was small enough, modular, and for which they could upgrade sensors on routine basis. 3-chip HD cameras were too big and costly and consumed too much power.  AIVL identified a lens and optical path that they really liked, so then it was just a matter of finding the sensor. After a year of searching, they decided upon Adimec-2000c/D camera, and it has been great for this system as well as others.

The AIVL imaging system was designed to produce HD-SDI in real time and then uncompressed stills, also in real time - the idea being that scientists need stills more than motion imagery.

This application provides an excellent example of the high image quality and rugged design of Adimec’s machine vision cameras.
