摘要

为解决自然光下视线跟踪系统注视点估计精度不高和头部运动受限问题

提出了一种基于虹膜和眼睛内角点特征的动态注视点眼动向量

并以虹膜面积信息对其进行标准化

以消除头部运动对眼动向量的影响.最后结合动态注视点眼动向量与多项式映射模型得到实时注视点

实现眼动向量与注视点的一一映射.采用该眼动向量可提高注视点估计精度

降低头部运动的影响.

Abstract

In order to deal with the constraint on accuracy and head movements in natural light

a novel dynamic gaze vector constructed by iris center and inner eye corner is proposed.The gaze vector

which is normalized by iris area to overcome the influences of head movements

is combined with the polynomial mapping model for real-time fixation point calculation

realizing the best mapping relation between the vector and the gaze point.The gaze vector proposed can improve the fixation point estimation precision and eliminate the influences of head movements.
