摘要
文中对基于红外电视法的眼动仪原理及实现做了详细的研究，详细讨论了瞳孔中心位置坐标的提取算法及ＡＳＩＣ实现、眼动仪的实时眼动测量的标定与显示、由瞳孔中心位置确定眼睛实际注视点的标定算法。
A detailed discussion on the Eye Movement Detection Device (EMDD) based on the infrared TV method and its realization are presented. The extraction algorithm of the center position coordinates of the pupils and its implement by ASIC, the real time eye movement measurement calibration and display, and the calibrations definition and algorithms, which determine the real fixation of the eye according to the position of iris centre, are discussed in detail. Finally the system performance is analyzed and discussed.
