摘　　要：为提高基于单一特征检测算法的准确率和可靠性,提出基于贝叶斯网络融合多个特征参数的检测算法。定位眼睛和嘴巴,利用两眼和嘴巴组成的三角形建立头部旋转模型,提取各特征的参数并用贝叶斯网络进行融合,用来判断驾驶员的驾驶状态,当出现非正常驾驶状态时给以警告。实验结果表明,该算法对于检测出驾驶员的疲劳度和注意力分散状态有较高的准确性。In order to improve accuracy and reliability of the detection based on a single feature, a detection algorithm based on Bayesian network fusing multiple features parameters is proposed. The algorithm locates driver＇s eyes and mouth, creates head revolution pattern, which is based on the triangle composing of two eyes and mouth, then inputs all the extracted character parameters to Bayesian network and makes a logic judgment, a timely warning is given when detecting drivers in an abnormal driving status. Experimental results show that the algorithm for detecting drowsy or losing attention has high accuracy.
