摘要

文中提供了一种基于SAA7113 H和FPGA芯片的车载图像记录仪的设计方案,详细介绍了I<'2>C总线设计、采集模块初始化、数据格式转换、实时图像采集与存储流程等问题.最后,通过系统仿真验证,结果表明,该记录仪能实现汽车在途行驶过程中的实时图像采集和记录,并得到了令人满意的效果,从而为事故的现场判断提供了及时可靠的证据.%This paper introduced a vehicle-bome image sampling; system based on SAA7113 H and FPGA chip. It detailed introduced the design of I2C serial 2-wire, the initialization of collecting module, the data format conve_ion and the collection and storage for the image data. And by the system simulation,it proves this recorder can accomplish collection and recording the image data during the car is running. It achieves a satisfied achievement and providing timely and reliable proof for accident scene judgment.
