Night Vision System Simulator Camouflage Digital Simulation and Evaluation Program. Phase One. Target Reflectance Alteration.

摘要

The Systems Analysis Team of the Visionics Technical Area has developed a digital image processing facility,the Night Vision System Simulator (NVSS) which affords the capability to perform a wide range of image processing operations. This system,which permits extensive analysis and modification of target and background imagery,provides not only a powerful technique for the simulation,evaluation,and design of night vision systems,but also a unique means to approach problems in camouflage technology. This report summarizes work completed on the first phase of a program directed toward the application of the NVSS to the advancement of camouflage technology. The intent of Phase One was to establish the capability to insert images of military vehicles into arbitrary background scene images,to impose a camouflage pattern upon the target,and to permit variation of the reflectance characteristics of the imposed pattern. The motivation for developing these techniques was to allow a controlled methodology for evaluating effectiveness of camouflage patterns with various characteristics on targets in a variety of backgrounds. The principal requirements in developing this capability included (1) derivation of the mathematical relationships involved in target reflectance alteration, (2) development of computer software required beyond that currently available in the NVSS software system (known as the EIKON SYSTEM), (3) documentation of system usage and training of personnel,and (4) performance of a typical camouflage simulation to demonstrate application of these techniques.
