This paper discusses the principle, structure and characteristics of a high-speed infrared image acquisition system. According to the application requirements of infrared imaging detection system, based on the Wishbone on-chip bus and PCI bus technology, a Wishbone-PCI Bridge IP core is used to design and implement a high-speed infrared image acquisition system on a single FPGA to solve the problem of high speed infrared image detector Transmission, real-time display and processing issues. Experiments show that: infrared image acquisition system is easy to use, reliable, to meet the performance requirements.
