Abstract

Calibration for infrared-based gaze trackers, which maps the estimated iris center locations in the image to monitor coordinates, is generally achieved with second-order polynomials. However, calibration performance tends to be poor for visible-spectrum gaze trackers (VSGT) due to the absence of corneal reflections from infrared light sources. This paper introduces a novel calibration method for VSGT that utilizes linear models based on the polar coordinate system. Experimental results demonstrate that false gaze data can be automatically filtered out through linear regression, significantly enhancing system accuracy.

基于线性模型的可见光谱凝视跟踪器系统标定

基于红外的注视跟踪器将图像中估计的虹膜中心位置映射到监控坐标，其校准通常使用二阶多项式来实现。然而，由于缺乏红外光源的角膜反射，可见光谱凝视跟踪器（VSGT）的校准性能往往较差。本文介绍了一种基于极坐标系统的线性模型的VSGT标定新方法。实验结果表明，通过线性回归可以自动滤除虚假注视数据，显著提高了系统的准确率。
