Abstract: This study investigates the real-time acquisition and Ethernet transmission of infrared images based on the ZYNQ hardware platform. After being captured by the infrared detector, the infrared image data is converted into CameraLink video data through infrared imaging circuitry. The CameraLink video data then undergoes serial-to-parallel conversion via an adapter board, followed by acquisition and User Datagram Protocol (UDP) network transmission of the CameraLink infrared video through the Programmable Logic (PL) and Processing System (PS) components of the AX7015 development platform, which is equipped with a ZYNQ-7000 series chip. Finally, a host computer program, designed in C++ within the QT software environment on a Windows operating system, is used to display and store the infrared video. The established infrared image acquisition and transmission system allows for image acquisition and transmission at a resolution of 1600× 1200, with a pixel depth of 24 bits and a frame rate of 16 frames per second on the host computer. The ZYNQ-based Ethernet infrared image acquisition and transmission system holds significant potential for exploration and research in the real-time acquisition of infrared CameraLink video, long-distance transmission, and subsequent infrared image processing.
