Study of Real-Time Detecting System for Driver's Safety
Zhang Qingnian, Zhou Zhi-zhong, Yin Daquan, Yang Jie · 2006
This paper presents a real-time detecting system based on the DSP processor. It uses real-time operating system DSP/BIOS to build tasks and interruptions, and will give out an incurrence of phonetic warning when the driver is tired. We use a comprehensive application of the complexion detection and differential frame arithmetic to make a correct orientation of the driver's face, then introduce a simple but credible method to judge the state of driver's mouth and a combination of horizontal integral projection and Hough transform to judge the state of driver's eyes.
