Abstract

The relative ease with which three-dimensional images are reconstructed from single hologram plates makes them an attractive alternative to the photogrammetrist for mensuration and mapping of close-range objects. For accurate metric work, the reconstruction geometry must be recovered to with-in fine tolerances, the values of which are given. A simple scheme for extracting positional information from holograms, as well as performing graphic and digital mapping, is explained and sample results included. To extend the capability to topographic terrain applications from aerial photography, the concept of the Holographic Stereomodel (HS), both fresnel and focused image types, is explained and relative advantages and disadvantages enumerated. The photogrammetric and geometric problems involved in the production of HS are expounded upon. Mensuration and mapping considerations from HS together with results obtained to-date are given.
