摘　　要：视线跟踪是基于多通道的人机交互技术的重要研究内容,而基于瞳孔-角膜反射技术的视线方向是目前应用最广泛的视线跟踪技术之一。瞳孔-角膜反射技术的主要目的是提取人眼图像中瞳孔-角膜反射向量作为视线方向计算模型所需的视觉信息,通过搭建红外光源设备提取瞳孔-角膜反射向量构建基于瞳孔-角膜反射技术的视线跟踪系统,为面向人机交互的视线跟踪研究提供可行的低成本解决方案。Eye gaze tracking is an important research content of human-computer interaction technology based on multiple channels, and the gaze estimation based on pupil center cornea reflection technique is one of eye gaze tracking technologies with the widest application. The pri- mary purpose of pupil center cornea reflection technique is to extract the pupil center cornea reflection vector in human eye image as the vision information of gaze estimation model. Constructs an infrared light device to extract the pupil center cornea reflection vector and builds up an eye gaze tracking system based on pupil center cornea reflection technique, provides a feasible and low-cost solution for the eye gaze tracking research of human-computer interaction.
