UNDERWATER STEREO PHOTOGRAPHY FOR HULL INSPECTION

A low cost system for taking underwater stereo photographs is described and background information covering the basic mathematics of stereophotography is presented. This system allows divers with no prior experience or skill in underwater photography to take high quality stereo photographs of ship's hulls. The photographs, which cover an area of about 2 inches by 3 inches, show such features as corrosion pits, paint blisters, and fouling organisms in great detail. Elevations or pit depths can be measured with an accuracy of about 1/64 of an inch. Several examples of stereophotographs taken with this system are included in the report. (Author)
