SUMMARY 



A complete underwater image facility should incorporate five 

 components: 



1) High-quality 3-D underwater dual band optics for data 

 collection. 



A. Shallow water system: compact, diver operated, no 

 immediate 3-D replay. 



B. Deep-water system; cameras mounted on submarine; 

 internal immediate 3-D review capability. 



2) 3-D video viewing system. 



A. Dual-band 3-D video projection theater. 



B. Single or dual-band 3-D video monitor display. 



3) Automated tracking of objects in 3-dimensional space and 

 in real time. 



Sequential-frame motion analysis of digitized objects 

 (e.g. ExpertVision/SUN computer system). 



4) Photogrammetric reconstruction and full image analysis 

 of stereopaired images. 



Image analysis computer (e.g. PIXAR). 



5) Mathematical modelling and 3-D computer animation. 



ACKNOWLEDGMENTS 



We have quoted extensively from Lipton's Foundations of the 

 Stereoscopic Cinema: A study in Depth and have paraphrased from 

 that excellent source with several of Lipton's shorter phrases 

 remaining intact. We thank him for his comments on our text. We 

 thank J. Mardesich of JayMar Engineering Services for design and 

 construction of the shallow water 3-D housing.
