摘要
讨论了一种基于红外电视法的眼动信号测量系统及其ＡＳＩＣ设计。该系统主要用于测量眼球的平滑追随运动。重点提出了一种新的瞳孔中心检测算法。该算法通过将眼睛的视频信号二值化后，用前后门限双检测的方法提取出瞳孔中心位置信号，并用ＡＳＩＣ设计完成。最后给出了系统性能测试结果和分析。
An eye movement measuring system based on infrared television method and its ASIC design is discussed in the paper.The measuring system is primarily applied to the measurement of the smooth following movement of eye.A new pupil central detecting algorithm is proposed.With the binaryzation of the eye video signal is realized,the pupil central position signal can be extracted by means of front and back threshold detection method,the algorithm will be completed with ASIC design.The testing results of the system performance and the analysis are given in the end.
