摘要
眼睛位置的快速准确定位是利用视觉方法对驾驶员的驾驶状态进行监测和预警的前提。采用一种基于灰度特征投影的方法进行眼睛位置的有效快速定位。在利用皮肤颜色YC rCb空间分布二维高斯模型可靠定位人脸区域的基础上,建立了进行眼睛位置检测的感兴趣区域,最后分别对灰度图像和二值化图像进行水平和垂直方向灰度投影确定眼睛位置。实验结果表明,该算法具有很好的可靠性和实时性,为后续驾驶员状态研究奠定了良好基础。
Eye location is the precondition to monitor driver＇s fatigue state with the help of image processing technique. This paper adopted gray projection method to locate eye position efficiently. Based on the skin color Gauss model in YCrCb space, the paper located the face region accurately and established the AOI for eye location. Finally, with the help of horizontal projection in gray image and vertical projection in binary image, the authors located the eye position efficiently and accurately. Experiments proved its good reliability and validity.
