摘要
文中主要研究使用普通的摄像头进行人眼视线方向的估计。在综合介绍了各种人眼视线检测方法的基础上提出了一种新的图像处理的方法来检测人眼视线方向。所采用的方法是先通过Hough变换计算出在低分辨率的情况下,人眼的上眼睑圆周及内外角点、虹膜中心后,然后在检测视线方向上采取了分部处理的方法。首先判断视角,再计算眼睛的视线方向。试验表明,此法比传统的虹膜检测法要精确得多。由于采取了分部处理,极大方便了计算机的实现。
Dose research on the gaze direction estimation of human eye using the common camera. A new gazing direction method based on image processing is developed after a variety of gazing direction methods are all supplied. The upper eyelid circle, （ inner and outer）eye comers and iris center coordinates can be calculated by Hough transform in low resolution. The method described is step - by - step treatment when directing gazing direction. First of all,the perspective is judged. Then gazing direction can be calculated. The experimental results validate that the method is more accurate than that of traditional iris detection. Moreover, the results can be calculated more easily by computer because of step - by- step treatment method.
