人们对健康和安全有很多关注，比如干眼综合症或开车时睡着。眨眼是反映注意力集中或昏昏欲睡程度的生理信号，因此眨眼检测系统有望获得眨眼信息。在许多眨眼检测系统中，需要接触设备或使用摄像头，会产生压迫感和抵抗感。本文提出了一种基于多普勒传感器的非接触式眨眼检测系统。通过为每个人设置阈值，并对眨眼和不眨眼进行分类，提出的系统可以对眨眼进行检测和计数。实验表明，该系统在检测准确率方面达到了92%的召回率。
There have been a lot of attention paid to health and safety, such as dry eye syndrome or falling asleep while driving. Blinks are the physiological signal that reflects the degree of concentration or drowsiness, and thus the blink detection system is expected to get blink information. In many blink detection systems it is necessary to contact the equipment or use with a camera and the feeling of oppression and resistance will arise. In this paper, we propose the contactless blink detection system with Doppler sensor. With the setting of the threshold for each person and the classification of a blink and non-blink, the proposed system can detect and count blinks. It is shown that the system achieves the recall rate of 92 % as for the detection accuracy by experiment.
