12 July 2000 Multipurpose underwater imaging and ranging camera: prototype system performance

SEACAM is a combination of a digital camera and an underwater sonar range finder that allows the precise range to the target to be measured simultaneously with the image. Given this measured range and the known field of view of the camera, the `plate scale' of the image (i.e., the number of millimeters/pixel) can be precisely determined, allowing for accurate estimates of the target dimensions. Two prototype systems have been developed: a `functional' camera that has all the functional capability of the final camera, but which is not packaged in the final form; and an `ergonomic' prototype that represents the first attempt at the final package design, but which is non-functional.
