摘要
近年来,以图像处理为基础,结合瞳孔-角膜反射技术的视线估计方法成为视线追踪研究的主要发展方向。现有的视线追踪系统有两个主要问题:1)视线追踪精度不高;2)操作不够方便,很多视线追踪系统严格限制了观测者的头部运动,给使用者带来了不便。通过对眼球模型和光学反射过程的分析,详细介绍了两种允许自由头动的视线估计方法。
The technique of eye gaze tracking,based on image processing and pupil center and cornea reflection technique（PCCR）,has made considerable headway in recent years.However,there are still two main problems preventing the use of eye gaze tracking in actual applications.1）Low tracking accuracy;2）Most system have low tolerance for head movement and require the users to hold their heads unnaturally still.In this paper,by exploiting the eye anatomy,two solutions are proposed to allow natural head movement.
