Abstract
A broad variety of passive ranging algorithms are currently being developed and enhanced at NASA Ames and elsewhere. Some of the factors resulting in algorithm variability include (a) number of sensors (e.g., stereo), (b) type of input sensors (e.g., multispectral), and (c) output display needs (e.g., history vectors superimposed on raw video). This paper describes a cost- effective, real-time general purpose (reprogrammable) computationally scalable digital processing architecture that enables researchers to perform comparative evaluations in a laboratory or field environment. Performance benchmark studies indicate that the passive ranging algorithm developed at NASA-Ames can be executed by a 32 processor based shared memory multiprocessor architecture, implemented on two (9U) VME boards.
