摘要
研究旨在协助驾驶员提高行车安全,减少疲劳驾驶带来的隐患。检测汽车驾驶员的唤醒状态,若得到疲劳信息,则发出警报。边缘检测算法,边界跟踪算法以及人眼定位算法以实现对驾驶员的监测;设计中定义眼睛闭合度的参数,衡量所采集到的眼睛图像的纵横之比,使系统对不同的人或同一个人的不同状态进行测量,保证实际应用价值。
The purpose of this research is to assist drivers to improve the road safety and reduce the hidden troubles. The system detects situations in which the driver is in danger, and sends the alert. Edge detection algorithm, tracing edge algorithm and eyes localization algorithm are used to fulfill the detection for the driver. The eye-state parameter defined by the thesis is meant to measure the ratio of length to breadth, so the system can detect different people or different situations of the same person. A software detection of driver＇ s fatigue state based on Matlab platform is performed through experiments.
