Abstract: Monitoring and analysing the state of driver’s facial organs by using the machine vision is one of the hotspots in the assistant safe driving system.This paper introduces the theory and structure of monitoring and warning system for driver’s driving behavior firstly，and then discusses the technical points in locating driver’s eyes in this system.In respect that the iris of a human being reflects and absorbs infrared rays at different wavelength differently，with special light sources of infrared ray，the author obtain different infrared reflected images，hereby catch the location of driver’s eyes by using the image-processing algorithm，which lay a good foundation for further information-collecting and state-analysing of driver’s eyes.Practice proves that the algorithm used in this paper acts in realtime and obtains excellent effect.
