Abstract
The pilot of a helicopter close to the ground estimates the range to objects partly by their motion, or optical flow, in his field of view. An automatic system for passive ranging can operate similarly. A conventional TV camera (generating approximately 512 by 512 pixel images 30 times per second) is an adequate sensor for a passive ranging system that could be used for navigation or that detects objects close enough to a helicopter flight path to be threatening.
