| 摘 要： | 根据汽车自动防撞系统前端图像采集模块对实时性处理要求高的特点，提出了1种基于FPGA的图像采集及VGA显示系统的设计方案。系统中FPGA主要完成对AD芯片的配置，从数字图像信号中提取时序信息和亮度信号，实现去隔行操作以及产生标准的VGA时序等。实验表明，该方案在满足图像质量要求的同时，较好地兼顾了实时性需求。

| Abstract: | An image acquisition and VGA display system based on FPGA was presented according to the real-time processing requirements for the automatic collision avoidance system.In this system,the main tasks of the FPGA are to configure the peripheral chips,extract timing information and brightness signal from the received data,deinterlace and generate standard VGA timing.The experimental results demonstrate that this method is feasible. |
