基于FPGA的车载多路图像采集传输系统的设计

摘要

The design of vehicular multiple image capture and transmission system based on FPGA was proposed in this paper .The system included four image acquisition nodes and a central control node ,the image acquisition node controlled CMOS image sensor to capture images data and then was stored in FLASH in real time .For shielding electromagnetic interference in the automo-tive environment ,the system usesd plastic optical fiber as communication media between acquisition node and control node .A com-munication protocol used for vehicular image data transmission was designed in this paper .As the experiment and test shows ,the system can achieve real-time multi-channel image acquisition and storage ,and bring all image data back to PC for display .%论文提出了一种基于FPGA的多路图像采集传输系统的设计方案，应用于车载环境中；系统结构包括4个图像采集节点和1个中心控制节点，采集节点由FPGA控制CMOS图像传感器采集图像，并实时存储于FLASH中；为屏蔽车载环境中的电磁干扰，采集节点与控制节点之间采用塑料光纤作为通信介质。论文设计了一种适合车载图像数据传输的通信协议，实验验证表明，系统能够实现多路图像数据的实时采集和存储，并将各路图像数据稳定地传回PC机进行显示。
