摘要

描述了用于分析扭眼运动的实时测量技术。该技术处理附着在眼睛上的隐形眼镜上的标记的视频图像。由于标记清晰、简单，省去了标记提取等复杂的图像处理，该方法测量精度高、速度快。此测量精度为0.08'的标准偏差。旋转角度可记录并显示在计算机上，采样频率为30Hz。

Real-time Measurement Of Ocular Counterroll By Processing Video Images

Real-time measurement technique is described for analyzing torsional eye movement. The technique processes video images of marks on a contact lens adhered to an eye. This method gives accurate and high-speed measurement , because clear and simple marks eliminate the complex image processing such as extraction of the marks. Accuracy of this measurement is 0.08' of standard deviation. The rotational angle is able to record and display on a computer with a sampling frequency of 30Hz.
