The invention discloses a driver state monitoring method, device and system. The method comprises the steps: obtaining a head image of a driver in a preset historical time period, wherein the head image of the driver is generated by an image acquisition device; analyzing the head image of the driver in the preset historical time period, and determining the state of the driver in the preset historical time period; if the driver is in a non-moving and non-speaking state in the preset historical time period, taking the heart rate and the breathing frequency of the driver in the preset historical time period as the state evaluation basis of the driver, wherein the heart rate and the respiratory rate of the driver are generated by a detection device based on the microwave Doppler effect. According to the technical scheme, the heart rate and the respiratory rate of the driver can be conveniently measured, and it is guaranteed that the measurement result has high accuracy.
本申请公开一种驾驶员状态监测方法、装置及系统。该方法包括:获得驾驶员在预设历史时间段内的头部图像,其中,驾驶员的头部图像由图像采集装置生成;对驾驶员在预设历史时间段内的头部图像进行分析,确定驾驶员在预设历史时间段内的状态;如果驾驶员在预设历史时间段内为未移动且未说话状态,则将驾驶员在预设历史时间段内的心率和呼吸频率作为驾驶员的状态评价依据,其中,驾驶员的心率和呼吸频率由基于微波多普勒效应的检测设备生成。基于本申请公开的技术方案,能够方便地测量驾驶员的心率和呼吸频率,并保证测量结果具有较高的准确性。
