摘　　要：给出了采用瞳孔-角膜反射向量法的实时视线跟踪系统总体结构及软件设计。首先简要介绍了系统装置组成及工作流程。随后详细说明了软件中的算法实现,包括角膜反射亮斑提取、瞳孔中心提取,摄像机系统匹配等关键算法。软件原型由VC++6.0结合OpenCV计算机视觉库编程实现。实验结果表明:该系统实时跟踪误差小于1°,并具有较好的鲁棒性。We present the general structure and software design of a real-time eye-gaze tracking system based on pupil-cornea reflection vector method. First,constitution of the system equipment was introduced briefly. Then,realization of the algorithms used in the software was described in details,including cornea reflection detection,pupil center extraction and calibration. The software prototype was developed using VC ＋ ＋ 6. 0 and OpenCV. Experimental results show that the system is robust,and its real-time tracing deviation is less than 1°. It provides a platform for interactive control using eye movement.
