摘要

针对现有视线估计方法存在的主要问题:限制使用者头部运动和个体标定问题,本文提出一种基于立体视觉的视线估计方法.建立了一种双相机双光源条件下计算眼睛光轴的five-spot模型,本模型估计眼球光轴三维方向只需要一次直线求交运算.以此为基础形成一种新的视线估计方法,本方法实现了自然头动视线估计,并且简化用户标定为单点标定.该方法的各个环节都满足实时性要求,为面向人机交互的视线追踪系统提供了有效的解决方案.

Abstract

For main problems of the existing gaze estimation methods which are that they restrict the head movement of users and the issue of individual calibration,this paper presents a gaze estimation method based on stereo vision.A five-spot model for the eye optical axis on the condition of two cameras and two light sources is set up.The model estimates the threedimensional orientation of the eye optical axis,which only needs one straightline intersection operation.On this basis,we forms a new gaze estimation method.This method allows natural head movement and minimizes the calibration procedure to only one time for a new individual.All aspects of this method meet the real-time requirement,which provides an effective solution for human-computer interaction gaze tracking system.
