摘要
采用S3C2440微处理器为控制芯片,基于嵌入式Linux操作系统设计了一种安全可视化倒车系统。通过嵌入式Linux操作系统内核驱动USB摄像头实时地监控车后状况,通过超声波测距结果与阈值的比较来启动语音报警模块以提醒驾驶员注意。经实验验证,该系统运行稳定,采集的视频图像清楚且实时性高,能够满足可视化倒车的要求。
A visual car reversing system is designed based on embedded Linux,using S3C2440 microprocessor as the main control chip.Embedded Linux kernel drives a USB camera for real-time monitoring of the situation at the rear of the car.The ultrasonic ranging data are compared with the threshold to start the voice alarm module to remind the driver.Experiments show the system runs stably and acquires clear real-time video images,meeting the requirements of visual reversing.
