为了实现对相机拍摄到的图像数据的实时显示,提出了一种基于Medium型Camera Link的多通道图像实时显示系统设计方案,并完成系统的软硬件设计;Medium型Camera Link可以同时接收和发送两组数据,经过基于“乒乓RAM法”的数据同步处理后,利用2组RAM交替进行写、读操作,可以实现高频高速的数据同步传输;该系统的硬件部分用来接收相机端的实时图像数据输入并对数据进行高速传输,软件部分实现对数据的筛选,整理,格式转换等功能,能够完成对图像的实时显示.
In order to realize real--time display of image data captured by camera, this paper puts forward a real time display system designing scheme of multi--channel based on Medium Camera Link and discusses the design of software and hardware. Medium Camera Link can both send and receive two data sets at the same time. The data synchronization based on Ping--Pong design, which two sets of RAM writing and reading alternately. The function of the hardware is to receive the real--time image data from the camera and transmit these data in high speed. The software in charge with the data screening, data sorting, format conversion and realize real--time display.
