[Fully automatic measurement of 3-dimensional eye movement with video-oculography].
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.


CONCLUSIONS
This method can eliminate the influence of eyelid overlapping and illumination, which can measure the 3-dimensional eye movement accurately.
