An Artificial Compound Eye Tracking Pan-Tilt Motion
Gwo-Long Lin, Chi‐Cheng Cheng · 2008
Abstract—The compound eyes of an insect can focus on prey accurately and quickly. From biological perspective, compound eyes are excellent at detecting motion. Based on the computer vision aspect, limited studies regarding this issue exist. Studies have verified that a trinocular visual system incorporating a third CCD camera into a conventional binocular is very helpful in resolving translational motion. Extended from this concept, this study presents a novel spherical compound-like eye of a superposition type for pan-tilt rotational motion. We conclude that as the number of ommatidium an insect has increased, capability for detecting prey increases, even for ambiguous patterns in each ommatidium. In this study, the compound eyes of insects are investigated using computer vision principles. Keywords—Biological imaging, Superposition-type spherical compound-like eye, Pan-tilt motion detection.
