本文提出了一种利用两对立体摄像机来估计显示器上视点(POG)的无定标方法。通过使用一对摄像头和两个光源,可以估计眼睛的光轴和角膜中心的位置。这一估计是通过使用角膜的球形模型来进行的。一对摄像头用于估计左眼的光轴,另一对用于估计右眼的光轴。光轴与显示器的交点称为光轴的点(POA)。POG被近似估计为连接两只眼睛与显示器的POA的线的中点。基于这种方法,我们开发了一个原型系统,并证明了POA的中点比每个POA更接近用户凝视的基准点。
This paper presents a calibration-free method for estimating the point of gaze (POG) on a display by using two pairs of stereo cameras. By using one pair of cameras and two light sources, the optical axis of the eye and the position of the center of the cornea can be estimated. This estimation is carried out by using a spherical model of the cornea. One pair of cameras is used for the estimation of the optical axis of the left eye, and the other pair is used for the estimation of the optical axis of the right eye. The point of intersection of optical axis with the display is termed the point of the optical axis (POA). The POG is approximately estimated as the midpoint of the line joining POAs of both the eyes with the display. We have developed a prototype system based on this method and demonstrated that the midpoint of POAs was closer to the fiducial point that the user gazed at than each POA.
