摘　　要：为便于科研人员在电视图像处理系统设计过程中对图像处理的新算法进行评估和测试,降低评估测试板硬件电路的设计复杂性,在此提出了解决方案,并实现了基于PCI总线的电视图像实时仿真系统的设计。该系统首先通过PCI插卡实现对电视图像进行采集、预处理和视频A/D转换,然后选用具有高速特性的PCI总线将数字化后的数字图像信息写入计算机系统内存,最后在计算机终端上,使用高级语言编程,完成图像处理和控制接口软件开发,实现计算机软件对PCI硬件设备的访问,数字图像的实时处理、分割、匹配等算法仿真。In order to evaluate and test the new algorithm of the image processing algorithm in the design process of television image processing system, and lower the design complexity of the hardware circuit in test board, a solution is proposed. The acquisition, pretreatment and A/D conversion of television images are realized with PCI card in the system, and then the high speed PCI bus is selected to write the digital image information into the computer memory; finally, in the terminal of computer, the image processing and the development of the control interface software are completed, and the real-time pro cessing, segmentation and matching of the complicated digital image are implemented by advanced language programming.
