高速数字图像采集显示系统的设计与研究

为满足实时显示高速数字图像的需求，分析了CameraLink接口技术和VGA（VideoGraphicsArray）接口协议的标准。根据VGA接口具有多种显示模式，设计了以FPGA（FieldProgrammableGateArray）为核心处理器的数字图像采集显示方案。FPGA通过CameraLink接口采集图像数据，并对图像进行缓存处理，对FP-GA构造VGA接口的时序信号和控制视频D／A进行数字量的模拟化。实验证明，该系统实现了图像的实时显示。人机交互和采集后的图像可以进行长距离传输。

Design and Research of High Speed Digital Image Acquisition and Display System

In order to display digital image in real-time at high speed, the Camera Link interface and VGA （Video Graphics Array） interface protocol standard is analyzed, according to the VGA interface which has a va- riety of display mode, adigital image acquisition and display program is designed by the FPGA （ Field Program- mable Gate Array） as the core processor, and the FPGA acquired image data through the Camera Link inter- face, then the image is cached and processed, as well as FPGA structure timing signal of VGA interface and con- trol the video D/A digital simulation, finally realize real-time display of images, simple control and transmit to long distance after prosessed image.
