Scientific imaging: problems and solutions for ROVs

The use of ROVs (remote operated vehicles) for science missions requires records of images for future qualitative and quantitative evaluations. The scientific use of standard ROV imaging systems is often difficult due to (1) the need to change the field of view of the video camera for piloting and (2) the often standard configuration of the still (film) camera. Precise calibration for areal or volumetric coverage is a necessity, and several variance minimizing procedures can be utilized. It is concluded that, considering the ROV as a mobile platform, imaging packages for specific science missions can be added which take advantage of the small-scale maneuverability and placement capabilities of the system.<>
