【Abstract】 To prevent the fatigue driving is given priority to subjective monitoring and objective detection,but the shortcomings existed on reliability,cost and detection method. Therefore,a set of anti fatigue driving alarm system by iris recognition based on DSP was designed. By referencing the research of scholars both at home and abroad,following the design principles of real- time,accuracy,simplicity and economy,and taking the algorithm of iris recognition as basis,the development was conducted based on the control technology of DSP microprocessor. On condition that the driver is not disturbed,the alarm system can identify the driver,record the driving time,identify fatigue driving and alarm. The test results showed that the structure of system was simple and realized the modularity. The modules of iris recognition and timekeeping satisfied the requirements of accuracy and real- time basically.更多还原
