Document Summary

Tao: specifies time to contact (do not need any of the duration process) Ratio of image size over image expansion is 1-1. Input is meaningful and there is information in ambient light. That information is the optic array (converges to your eyes) Converted into eyes = point of observation (wherever you are in space; light bounces/reflects off something into your eyes) What does this all mean?- light is the medium for vision. It takes the patterns out of the retina and into the light. Objects are seen on a ground plane with a background. In depth they are seen in relation to the background texture (ex: tiles) Optic array: (picture of bird flying over field with arrows= optic array) Optic flow is the optic array in motion. If there is constant velocity of approach then there is an exponential increase in the image e(cid:454)pa(cid:374)sio(cid:374) rate, (cid:449)hi(cid:272)h (cid:373)ea(cid:374)s so(cid:373)ethi(cid:374)g (cid:449)ill hit (cid:455)ou if (cid:455)ou do(cid:374)"t (cid:373)o(cid:448)e out of the (cid:449)a(cid:455)
