ABSTRACT
OBJECTIVE@#To bring forward a new method for automatic measurement of the translation and rotation of the eye movement.@*METHODS@#A centroid method, edge filter, and ellipse fitting were used to get the accurate position of the eye center. The rotation angle of the eye was determined by Fourier-Translation arithmetic operators.@*RESULTS@#The simulation image test and initial clinical experiment obtained a good precision.@*CONCLUSION@#This method can eliminate the influence of eyelid overlapping and illumination, which can measure the 3-dimensional eye movement accurately.
