This paper introduces a high-speed infrared image acquisition system based on PCI Express. The paper is mainly on the hardware design of the PCI-E acquisition board and the software design of the host. The PCI-E acquisition board uses FPGA as the main controller. The software design of the host includes drivers and application program. According to the experiment result, the system can perform real-time acquisition of infrared image stably and reliably. The system can be applied to real-time acquisition of infrared image with high frame rate and massive data.
