高分辨率是红外成像技术的发展方向。为了实现高分辨率红外成像系统实时处理, 提出一种基于SOPC技术的解决方案。以软核CPU Micro Blaze为核心构建软硬协同处理架构, 完成非均匀校正、图像降噪、直方图均衡等图像处理, 解决大数据量图像高速处理问题, 满足实时性要求。相比于传统FPGA+DSP的硬件架构, 该方案易于实现低功耗和小型化, 且可靠性高、通用性强。设计的高分辨率红外图像处理系统具有清晰度高、对比度高、图像细节清晰等优点。

High-resolution is the trend of infrared imaging technology. In order to implement high-resolution infrared imaging in real-time, a technical scheme based on SOPC technology is proposed. Hardware and software co-design architecture is constructed with the core of CPU Micro Blaze to complete such image processing procedures as non-uniformity correction, image denoising, and histogram equalization enhancement, so as to solve the problem of high-speed processing of large-data images and meet the real-time requirement.Compared with traditional hardware architecture of FPGA+DSP, this technical scheme has lower power consumption and is miniaturized with high reliability and high generality. The designed high-resolution infrared image processing system has the advantages of high definition, high contrast and clear image details.
