On Measurement of Angular Displacement of Human Eye using a 2-D CCD.

A method of measuring the angular displacement of the human eys is investigated through the use of a simple system comprising a 2-D CCD and a personal computer. The data that are on a rectangular coordinate are transformed into the data on a polar coordinate, and some examples of the angular displacements of the human eye obtained by calculating a cross-correlation function between the iris pattern and its reference pattern are shown. We conclude that it is possible to measure the counter- rolling of the human eye by the above method.
