摘要
本文提出并实现了基于实时视频检测驾驶员疲劳度的信息融合系统。使用红外摄像仪和高速DSP相结合,实时监控驾驶员的疲劳症状,提炼出特征信息,经FPGA系统加以信息融合技术处理后得到疲劳度,自动判断驾驶员是否进入疲劳状态,根据疲劳度的不同发出警告信号。经实际测试表明,使用信息融合技术有效地提高了系统判断驾驶疲劳状态的精确度和系统的鲁棒性,具有93%以上的正确率。
This paper presents the advanced system with an information fusion approach for real-time video detection of driver＇s fatigue. The infrared cameras and DSPs are used to simultaneously monitor and analyze driver＇s fatigue symptoms. The veracity of the system will be strengthened to determine driver＇s fatigue driving status through the information fusion technology processing the feature information which comes from the DSPs. In addition, the system is capable of automatically drawing the conclusion that the driver is falling asleep and issuing different kinds of warning signals depending on the level of the fatigue status. It was proved to be accurate more than 93%.
