Paper Abstract

A mechanical-electrical film digitizing apparatus was developed to enable highly accurate film analysis at low cost. The design incorporated the use of X and Y axis cursors, overlaid on a rear projection screen material, with cursor positioning controlled by reversable motors through a handheld controller. Three separate schemes were investigated to provide a digitizing accuracy of 10,000 by 10,000 points on a 1 meter by 1 meter screen. Additionally, an option was incorporated to provide a 1000 by 1000 point field, with an off-set capability of up to 9000 data points, for use in digitization of film where an initial point of reference moves out of the camera field of view. Features to enable display, storage, and computer manipulation of data were incorporated, using digital circuits available at the retail level. Total system cost fOr the digitizer was less than 800 dollars.
