Night Vision Goggle Simulation
Abstract
The use of Night Vision Goggles (NVGs) has increased dramatically and so has the number of accidents attributed to NVG aided flight. The work performed under this project represents an investigation of the use of Night Vision Goggles and the exploration of a method for providing simulation of night vision imagery in an interactive flight simulator environment. The characteristics of the Aviators Night Vision (ANVIS) Goggles were investigated and are summarized. A helmet mounted display concept was developed and a testbed was developed. A commercially available magnetic tracking device was obtained to provide head tracking, and, through a in-house designed interface, was interfaced to a SEL flight computer and various image generators. A Z-transform based predictive algorithm for compensating for the throughput delay image effects of a head tracker, flight computer, and image generator was developed and also integrated into the testbed for evaluation. The helmet display NVG concept represents a good alternative to full up flight simulators of the Weapons Tactics Trainers (WTT) type, and could provide significant enhancements to classroom and on the job training. A part task trainer could be developed using the helmet mounted NVG concept that would bridge the gap between classroom and flight.
