| Abstract: | Driver fatigue detection based on digital image processing is potentially a promising online detection method.It has little interference to driving activities.Researches in this field at present have commonly endowed in algorithms but little about system design.This paper discusses a reduced minimum system centered by a single FPGA chip for infrared video collecting.Key design issues of this sort of system are elaborated.The real time collection,storage and display functions of driver infrared image are imp... |
