The authors describe a novel technical approach to accurately measure surface area and other morphological characteristics of corals and similar irregular objects from underwater photography. A standard Nikonos camera system was used with a slide-scanner to produce multiple overlapping images of the object. PhotoModeler software was used to process the images and build a 3-D model of the object, which was subsequently analyzed using 3-D computer-aided design (CAD) packages.
