摘要
介绍了以三星S3C2410微处理器为核心,设计了一种基于Linux嵌入式系统的新型汽车记录仪。在传统记录仪基础上提出增加人眼检测模块,有效约束驾驶员不良驾驶习惯,防止疲劳驾驶,在被动记录事故数据基础上实现对驾驶安全的主动预防。系统总体包括数据采集、数据存储、串口和USB通讯、LCD显示、语音报警、人眼检测、上位机软件等。
A new recording instrument about the state of vehicle running based on ARM and Linux monitor system is introduced,Including common design,real-time images to detect,track and analyze the state of eyes and pick-up characteristic parameter of eyes was suggested, count closing time of eyes in succession within regular hour,judge the tired degree.The system consists of CMOS image sensor for real-time image capture,large volume image data memory subsystem of NAND Flash.The system control was realized by ARM9 chip S3C2410.
