Real-time stereopsis using FPGAs
Peter Corke, Paul A. Dunn · 2002
A real-time stereo vision system, based on configurable logic boards, is described. Many reported stereo-matching systems are based on numerically intensive measures such as normalized cross-correlation which is expensive in terms of logic. Non-parametric measures require only simple, parallelizable, functions such as comparators, counters and exclusive-or, and are thus very well suited to FPGA implementation.
