文档介绍：模糊疲劳辨识系统
摘要
在现代工业控制领域,伴随着计算机技术的突飞猛进,出现了智能控制的新趋势,其中模糊系统和模糊逻辑领域就成为了一个很重要的研究热点,近年来,在过程控制、建摸、农业生产和军事科学等领域得到了广泛应用,本论文主要是描述一个利用模糊逻辑判别驾驶人是否疲劳的安全警告系统(Drowsiness Warning System)。此系统利用瞌睡判别技术来辨识驾驶员的疲惫程度,此方式是透过摄影装置撷取影像,再利用影像处理技术(色彩空间改变、影像的像素累加、影像平滑处理、影像灰阶处理、影像二值化处理等技术)与瞌睡判别技术来监视驾驶员的精神状况,侦测其是否处于清醒状态。一旦系统侦测到驾驶员处于疲劳状态,系统自动予以警示,确保行车之安全。

Fuzzy fatigue recognition system
Abstract
In the modern industry control domain .with the development puter technology progressing. The intelligent control has e a new tendency. Also. The fuzzy system and the fuzzy logic domain has e a very important research hot spot .recently. The fuzzy system and the fuzzy logic has obtained the widespread application in the process control, constructed knowledge, agricultural production and military science domains and so on. This paper describes the development of a vehicle driver drowsiness warning system using fuzzy logic image processing technique. This system recognizes pilot's exhausted degree by using sleepy distinction technology. This way is taken by the Camera to pick up the phantom. And use the image process technology (color space change, phantom picture element accumulates, phantom smooth processing, phantom gray scale processing, phantom binary processing and so on) to monitor pilot's energetic condition again with the sleepy distinction technology, detect it whether to be at the sober condition. Once the system detects the pilot to be at the state of fatigue, the system gives the caution automatically, ensures security of the driving.
Key words:drowsiness warning system ;vehicle safety; image processing; fuzzy logic
