The invention provides an intelligent vehicle-mounted box and a driving fatigue monitoring method. The method comprises the following steps: collecting an image of a driver through a camera on the intelligent vehicle-mounted box, analyzing and processing the image, extracting key features used for representing the fatigue degree from face features, and evaluating the fatigue level of the driver. The key features representing the fatigue degree comprise eye closing frequency and eye blinking frequency, and the key features of the mouth comprise mouth closing frequency. According to the technical scheme provided by the invention, the face of the driver is accurately captured from a plurality of faces of different frames of images, and key features are extracted, so that the misjudgment rate of fatigue monitoring can be reduced while real-time monitoring is ensured.

    本发明提供一种智能车载盒子及驾驶疲劳监测方法,利用智能车载盒子上的摄像头采集驾驶员的图像,对图像进行分析处理提取人脸特征中用于表征疲劳程度的关键特征评估驾驶员疲劳等级。表征疲劳程度的关键特征包括:眼睛闭合频率和眼睛眨眼频率,嘴部关键特征包括嘴巴的闭合频率。本发明提供的技术方案中包括精准地从不同帧的图像的多个人脸中捕捉到驾驶员的人脸并提取关键特征,在保证实时性监测的同时能够降低疲劳监测的误判率。
