METHOD OF EVALUATING A RECONSTRUCTED SURFACE, CORNEAL TOPOGRAPHER AND CALIBRATION METHOD FOR A CORNEAL TOPOGRAPHER

摘要

A Method of evaluating a correspondence between a target surface and a reconstructed surface representing the target surface is described. The reconstructed surface can be constructed by processing information obtained by illuminating the target surface with a pattern of light of a stimulator source, and capturing a reflected image of the pattern of light on an image target, the method further comprising the steps ofDetermine a reference image point on the image target corresponding to a reference stimulator point on the stimulator source,Calculating for the reference image point, using the reconstructed surface, a residual representing the correspondence between the target surface and the reconstructed surface.Displaying the residual together with the reflected image.
