摘　　要：为了获得高速运动目标的位置与姿态信息,分析目标瞬态事件发生的机理和运动规律,提出了以现场可编程门阵列(FPGA)为核心的高帧频图像采集及实时显示的设计方案。研究了高速互补金属氧化物半导体(CMOS)数字图像传感器LUPA1300-2,并以此为基础研究了500fps图像采集及实时显示系统的关键技术,以FPGA为核心设计了基于高速低压差分信号(LVDS)接口的图像采集模块、色彩复原模块及图像缓存模块。通过图像采集实验,验证了系统设计稳定可靠,满足现场实时性的要求。To obtain the position and attitude information of high-speed moving target and analyze the mechanism of the occurrence of transient events and features of target motion, a high-frame-rate image acquisition and real-time display system based on field-programmable gate array （FPGA） is proposed. It is based on high-speed complementary metal oxide semiconductor （CMOS） digital image sensor LUPA1300-2 to realize the key technology of the 500 fps image acquisition and real-time display system. The modules of image acquisition, color restoration and image cache based on high-speed low-voltage differential signaling （LVDS） interface using FPGA have been designed. The system is stable and reliable through the experiment of image acquisition, and meet the requirement of the real-time acquisition system in the field.
