驾驶防瞌睡装置用于实时监测司机眼皮活动情况 ,介绍了用于该装置基于灰度积分投影的人眼快速定位方法。首先利用图像的垂直灰度投影曲线确定人脸左右边界 ,然后利用水平灰度投影曲线确定人眼位置 ,最后利用阈值分割及边缘检测进行人眼开闭情况检测。实验表明 ,该方法对于驾驶防瞌睡装置中的人眼位置判定具有很强的实用价值 Driven napping device for real-time monitoring driver eyelid activity, introduced for the device based on gray integral projection of the rapid eye location method. First, the vertical gray projection curve of the image is used to determine the left and right faces of the human face. Then, the horizontal gray projection curve is used to determine the position of the human eye. Finally, the threshold detection and edge detection are used to detect the opening and closing of human eyes. Experiments show that this method has strong practical value for judging the position of the human eye in driving a sleepy device
