中文摘要：

利用计算机视觉方法对驾驶员进行驾驶状态监测和预警过程中，面部特征的快速准确定位是技术关键。针对驾驶室背景的视频帧图像，提出一种基于数学形态学，面部结构特征和灰度积分投影的方法，实现了对驾驶员两眼睛中心和两鼻孔的精确定位。实验表明，该方法具有较高的准确率和鲁棒性。

英文摘要：

In the process of supervising driver＇ s condition with computer vision, fast and accurate location of facial features is the key technology. In view of the video sequence with the background of a driver＇ s cab, a method based on mathematical morphology, facial structure and gray integral projection is proposed to achieve the precise positioning of the driver＇ s eyes. The experiment indicates that this method has a high rate of accuracy and robustness.
