To bring forward a new method for automatic measurement of the translation and rotation of the eye movement.
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.
The simulation image test and initial clinical experiment obtained a good precision.
This method can eliminate the influence of eyelid overlapping and illumination, which can measure the 3-dimensional eye movement accurately.
提出一种自动测量眼球运动平移和旋转的新方法。
采用质心法、边缘滤波和椭圆拟合来获取眼球中心的精确位置。通过傅里叶-平移算术运算符确定眼球的旋转角度。
模拟图像测试和初步临床实验取得了良好的精度。
该方法可消除眼睑重叠和光照的影响，能准确测量三维眼球运动。
