Abstract:

A hardware system for driver fatigue detection is designed based on DM642, which includes master controller module, video capture module, video output module, alarm module and other related circuits. Based on the research status at home and abroad, the theoretical basis of fatigue state judgment is determined. The eye fatigue characteristic was combined with image processing technology, face detection technology and PERCLOS fatigue testing method to judge the fatigue state of the driver in real time . If in a state of fatigue, an alarm is issued, which can effectively prevent the occurrence of a traffic accident. After the testing of system hardware and software, The results show that the scheme can effectively identify the fatigue state of the driver, and it has high speed, good real-time and high robustness.
