基于开放式多媒体应用平台的汽车安全监测系统设计

采用以TI达芬奇技术芯片为核心处理器的硬件平台，以依据硬件裁剪定制的Linux系统为基础，设计开发了基于计算机视觉的汽车安全系统.该系统具有超速预警、安全车距预警、事故求助、车辆位置获取和车辆防盗、防抢等功能，且系统体积小、功耗低、使用方便，易于功能扩展和升级，在高速公路上开展安全监测试验表明，文中提出的算法漏检率低于5%，误检率低于0.5%. 

Detection System Based on Open Multimedia Platform for Vehicle Safety

A hardware platform, a computer vision-based vehicle safety system was proposed, taking TI''s DaVinci chip as the core processor and taking the embedded Linux in conformity to hardware configuration as the software development platform. The system was provided with some functions, including overspeed warning, vehicle distance judgment, accident assistance, vehicle position determination and vehicle anti-theft. Highway test results show that the missing rate of the algorithm is less than 5% and the false detection rate is less than 0.5%. Due to small size, low power consumption, high usability, high expansibility and upgradeability, this system can be widely used in various vehicles.
