基于Camera Link的高速图像采集处理器

High Speed Image Grabber and Processor Based on Camera Link

设计了基于Camera Link标准的高速图像采集处理器,可以对高速的数字相机进行图像采集及实时图像处理。系统采用FPGA和DSP作为主要的内核处理单元,FGPA完成图像的采集和预处理,DSP完成复杂的图像处理任务。详细给出了处理器的结构设计和一些关键技术,如Camera Link接口技术、高速缓存以及显示技术、图像处理和输出接口设计等。经过调试,系统最终可以实时完成1000帧/s的图像采集和处理任务。

This article introduces a new type image grabber and processor based on Camera Link.The system can grab the digital camera image data,then process it at real-time.As the main processors of the system,the FPGA accomplishes the test of images grabbing and pro-processing,the DSP accomplishes the test of more complex images processing.The design about the processor＇s structure is described in detail and some key technologies are introduced,such as Camera Link interface technology,cache memory and display technology,image process and output interface technology,et al.The system can reach 1 000 frames/s for real-time image grabbing and processing after the system has been debugged.
