Research on the key technology of 500 fps image acquisition and real time display

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.
