摘　　要：结合了传统三维重建及眼部跟踪模型,结合透视投影模型的改进型三维重建法,解决了明暗法非唯一解问题,得到了眼球必要点的三维坐标;建立头动补偿的异面直线模型,它通过眼球重建所求三维坐标点,得到异面直线模型,无须计算深度信息,直接通过建模求解与补偿机制,快速得到视线落点位置,减少了设备复杂性,并提高了算法的精度。因此,基于眼球重建异面直线模型的双目视线跟踪算法是计算机视觉跟踪方法的一种创新,为人机交互应用提供了新的思路。This paper combined 3D reconstruction method of light and shade with perspective model,and proposed advanced3 D construction method based upon perspective model,it reconstructed the eyeball model and solved the ambiguity problem.What＇s more,it simplified the acquisition of depth information. It also proposed a skew lines model which did not need to calculate the depth information. With the help of model reconstruction and head motion compensation mechanism,high precision and real-time vision tracking result could be gained. This method reduced the complicacy of the equipment. In a word,binocular eye tracking algorithm based on eyeball rebuild skew lines model is an innovation for computer vision,and a new way for human-computer technique.
