Abstract
A mensuration apparatus for converting film images and paper drawings into digital photogrammetric arrays to be computer processed, displayed, mensurated and analyzed. This mensuration apparatus includes a table on which a translatable camera and a reseau assembly are mounted. The reseau assembly includes an object mounting plate for mounting an object such as a photograph, map, or the like, and a grid mark system for superimposing grid marks on the object. The translatable camera includes a solid state camera having a two-dimensional array of light sensor elements mounted over the reseau assembly in a translatable mounting apparatus. Said translation camera can be moved to any desired position over the reseau assembly, as well as toward and away from the reseau assembly, forming three coordinate systems, which are correlated together for precise mensuration of an object image digitized by the solid state camera.
