SYSTEM FOR MOVEMENT TRACKING OF SPHERICAL OBJECT

摘要

A system for registering a series of video images of a spherical or quasi-spherical surface subject to movement relies on projecting at least four diffusely scattering spots of light on the surface in a preferred angular manner, and monitoring the movement of images of the light spots relative to a reference image of the light spots. The preferable object is the cornea of a person's eye.
