Paper Abstract

A passive range estimation algorithm developed at NASA Ames Research Center for pilot- aiding during low-altitude helicopter operations has been tested off-line using imagery and motion data collected in flight, and has demonstrated excellent results using this real-world data. In developing a realtime computer architecture for this algorithm, several candidate parallel processing approaches have been previously investigated. A realtime parallel computer system based on the most-promising approach has now been implemented. This paper describes the hardware and software architecture of the realtime passive ranging system. The performance attained with this system indicates that realtime passive ranging can be achieved with a computer system compact enough for installation on board a helicopter.
