Paper Abstract

In the field of Automotive Safety there is apparently an absence of a solution to the problem of sensing spacial intensity data in a rapidly scanned field of view and processing this data in real time. DBA Systems, Inc. has developed and is fabricating a system that will, under program control, direct a non-storage photo-emissive device beam to a discrete X, Y address location. Intensity information at and around this point is then transferred to memory for real time processing. The Automatic Programmable Film Reader (APFR) presents itself as a highly useful system when applied to the field of Automotive Safety. The APFR locates up to 30 points of interest on a single frame of film. The system then tracks and stores the new locations of these points in the ensuing frames. Tracking, locating, and advancing of film is accomplished fully automatically under program control and does so with an accuracy of less than 10 microns. The total time required to track and store the locations of the full complement of points per frame is 10 seconds. The ability to track points of interest within a given field of view in real time with a non-storage camera is further enhanced by a choice of optics and projection heads enabling the operator to observe 16mm, 35mm or 4" x 5" cut film records. In addition to the storage of location information on each frame, the frame itself is magnified and projected onto a viewing screen for visual observance by the operator. This paper describes the solution to the problems of inaccurate and inefficient film analysis. The solution lies in the replacement of human "eyes" with an optical sensor capable of digitizing information and transferring the information at a high throughput rate to a computer for real time processing.
