The bee sees distance of object, judgement and mankind differ, much simpler than the mankind. The bee is compound eye insect, hundreds of looks are shot severally to different way, the bee forms three-dimensional picture with this kind of simple method namely. People is when shift, the picture that the thing presents to go up in retina also is moving, this kind of motion of the image on retina is inspected for “ namely shed ” . Nevertheless, the motion of the motion of the image on retina and observer itself has very big concern. For example, run when you when moving, the object in eye shot is closer from you, the speed that the picture that it forms on your retina moves is jumped over it seems that fast; People is in on the train when content of exterior seeing a window, the arboreous outline on distance horizon moves very adagio, the rate that the farmhouse with a bit some closer distance moves at the moment from us is much rapidder, and the telegraph pole that relies on railroad closely, crawl is like greased lightning kind of thrill through.
The bee inspects the flight that spreads ” to adjust his according to “ just about. The nerve biologist of institute of unit of round-the-clock bee flight Mandiyamu the person such as Silinifansa passes · experimental discovery, when the bee flies if detect suddenly,something put oneself in another's position has moved fast, can deciding is a fraise then and quickness changes direction, leave that object. In the experiment, they guide a bee to fly into a conduit, the result discovers buzzing bee colony flies well and truly to conduit center to be in, go to down conduit again in fly. “ bee colony is done so, the speed that for the sake of balancing conduit both sides the image in apian eye moves. For the bee that ” sheds ” range finding to using “ to inspect, the resembles shift career that scenery fashions in its eye is slower, the distance of scenery is farther, vice versa. The bee is inspected through “ so namely shed ” to observe scenery, self-adjusting flight speed: Fly at open ground, advance quickly, when passing complex landform, criterion rein in speed.
“ is inspected shed ” to also help a bee descend smoothly. Normally, when coming down on the bicycle that people wears from travel, can one kind is close to region rate to jump over fast feeling it seems that more. And the bee should stop when falling to go up in the object, use “ is inspected shed ” to observe scenery, automatic rein in flies speed, adjust the angle with the ground, the elephant that makes scenery is formed in its eye moves equably, come true to descend smoothly thereby. It resembles “ an autopilot, you need not worry about when the flight speed and flight height, it can have done everything for you. ”
