摘　　要：针对交通领域驾驶员安全问题,提出一种基于S5PV210芯片的驾驶员情绪感知系统设计方法。采用S5PV210芯片处理器,加载linux2.6.30内核,由USB工业相机获取驾驶员人脸图像,利用一种基于稀疏表示的表情特征数值分类方法,获得驾驶员人脸表情特征数值,最后通过映射获得驾驶员情绪状态结果。当出现预设情况时给予警示,并将实时数据通过WIFI通信网络发送回管理中心服务器。仿真实验表明,本系统目前对驾驶员情绪的正确识别率可以达到80%以上。This paper presents a driver emotion perception system based on S5PV210 chip to the driver security problem. Adopt the processor of S5PV210 chip with linux2.6.30 system, the facial images of the driver captured by a USB industrial camera. The driver＇s facial expression features were obtained by a class method of sparse representation , analysis of monitoring system of driver＇s mental state, finally obtaining the driver＇s mental state results. When the condition is satisfied, the system is automatic alarmed and send the data to the center of servicer through WIFI. Simulation experiments indicate that the recognition rate of our emotion perception system can be above 80%at present.
