高速红外图像数据采集系统的设计

在红外空空导弹中，红外成像系统在图像处理中所涉及的数据量大, 难以实现实时处理。针对这一问题，介绍了一种基于RapidIO和PCI--Express的高速红外图像数据采集系统，重点讨论了以高速串行总线的XMC底板和XMC接口板为框架结构的关键模块图像采集板卡的设计。该系统不仅具有双通道数据采集功能，还具有双通道数据播发功能。每通道的采集速率达到1.2 Gbps，码速率为0～400 M。该系统可实现高帧频红外图像的实时采集和显示。

Design of High-speed Infrared Image Data Acquisition System

In an air-to-air missile, the amount of the data to be processed by the infrared imaging system is too large for real-time processing. To address this problem, a high-speed infrared image data acquisition system based on RapidIO and PCI-Express is presented. The design of a key modular image acquisition card which uses the XMC base plate and XMC interface board of a high-speed serial bus as its frame structure is discussed emphatically. The system not only has a dual channel data acquisition function, but also has a dual channel data broadcast function. Each channel has a data acquisition rate up to 1.2 Gbps and a code rate in the range 0 M to 400 M. The system can implement the real-time acquisition and display of high frame rate infrared images.
