An optical system for guidance of terraine following in UAVs

Srinivasan, Mandyam V; Thurrowgood, Saul; Soccol, Dean

Description

There is considerable interest in designing guidance systems for UAVs that use passive sensing (such as vision), rather than active sensing which can be bulky, expensive and stealth-compromising. Here we describe an optical sensor, based partly on principles of insect vision and optic flow analysis, for measurement and control of height above the ground. A video camera is used in conjunction with a specially shaped reflective surface to simplify the computation of optic flow, and extend the...[Show more]
