摘要
人眼精确定位是疲劳驾驶系统预警的关键,而针对人眼定位准确率低、实时性差的问题,提出一种基于八方向Sobel算子的人眼定位算法。首先由人脸“三庭五眼”和人眼灰度积分特性的先验知识粗定位人眼,再由扩展的八方向Sobel边缘检测算子实现人眼精确定位。研究结果表明,与传统灰度积分投影方法相比,该算法可降低计算复杂性,大幅提高人眼定位准确率,具有良好的实时性和鲁棒性。
Eyes location is the key in fatigue driving system of early warning.As the issue of low accuracy and poor real-time ability,human eyes location based on eight direction sobel operator algorithm has been proposed.Based on the prior knowledge of the“three court five”and gray-level integral projection,we can coarse positioning of eyes in the facial region.Then use eight direction sobel operator method for precise position.Experimental results show that the algorithm reduces the complexity and improves the accuracy of eyes location,which is compared with the traditional gray integration projection,and has the advantages of real-time and robustness.
