【摘要】 常用的超声波倒车雷达能够准确测量车尾与车后障碍物的距离,但实际倒车环境存在视觉盲区,司机很难判断障碍物的确切位置,感知地坑或低矮障碍物.针对这一问题,本文设计了一种辅助倒车系统,以s3c2410处理器和嵌入式Linux2.6.14.1操作系统为平台,选用USB接口摄像头完成车尾图像数据采集与实时显示,辅以测距报警模块实现实时测距,并在进入危险距离时提供语音报警.经实验调试,系统运行稳定可靠,后视图像直观真实,测距准确,增强倒车的安全性和可靠性。更多还原

【Abstract】 The commonly used of ultrasonic parking sensor can measured the distance between the rear of the car and obstacles accurately,but exist visual blind spots in the environment of actual car backing.The driver can not determine the exact location of the barrier,perceived to pit or low barrier.In response to this problem,This paper has designed a reverse-assisted system that taking s3c2410 processor and embedded Linux operation system as a platform,Using USB interface camera to acquire the rear image data and display real-time,by ranging and alarm module to measuring the distance and provide voice alarm when it access a dangerous distance.After the debugging of experiment,the system is stable and reliable,measure correctly that enhance the safety and reliability of car backing.更多还原
