摘　　要：为实现干扰条件下的眼睛睁闭状态检测,提出了一种新的基于径向对称变换的眼睛状态检测方法.该算法充分利用了睁眼状态下瞳孔的灰度特性及其径向对称特性,有效地解决了光线变化、不均匀光斑、睫毛和镜框等因素的干扰.大量的实验结果表明,该算法具有较好的检测效果,对各种干扰情况有较强的鲁棒性,并且检测速度快,能够达到实时要求,而且能在眼睛状态检测的同时实现瞳孔定位.In order to detect eye dual-state under disturbed conditions, a new algorithm was proposed based on radial symmetry transform, in which the distribution of pupil gray value and its radial symmetric property with eyes open were fully utilized to realize eye detection. Our algorithm could effectively eliminate the interferences of illumination change, spectrum, eyelashes as well as glasses frames. Experimental results show that the proposed algorithm produces a relatively good detection result. It not only has strong robustness to various interferences and achieves a faster detection that can satisfy the real-time requirements, but also realizes pupil localization at the same time of eye state detection.
