| 针对非制冷红外相机图像存在背景噪声大、对比度低以及基于个人计算机的视频采集系统便携性差等问题，提出了一种基于ZYNQ全可编程片上系统平台的红外视频采集系统。该系统通过集成直方图均衡、核范数最小化以及一维引导滤波等多种图像处理算法，在提升图像对比度的同时有效抑制噪声。为了加快处理速度，系统采用直方图伪均衡方法优化直方图均衡的计算效率，并针对核范数最小化和一维引导滤波设计了高效的滤波模块架构，实现了两种滤波方法的高速并行处理。实验结果表明，所提出的红外视频采集系统能够将图像的粗糙度、均方根对比度和信息熵分别提升至原始图像的17.4、3.15和2.16倍，显著改善了红外图像的视觉效果和细节表现。基于ZYNQ平台的设计不仅具有高度集成化的特点，还具备较快的处理速度，能够满足实时处理的需求。与传统的PC平台相比，该系统在便携性、功耗和成本方面具有显著优势，为红外视频采集技术的实际应用提供了一种高效、可靠的解决方案。 |

| Aiming at the problems of high background noise, low contrast and poor portability of PC-based video acquisition system in uncooled infrared camera images, a ZYNQ fully programmable system-on-chip-based infrared video acquisition system is proposed in this paper. By integrating many image processing algorithms such as histogram equalization, kernel norm minimization and one-dimensional guide filtering, the system can improve image contrast and effectively suppress noise. In order to accelerate the processing speed, the system uses histogram pseudo-equalization method to optimize the computational efficiency of histogram equalization, and designs an efficient filter module architecture for kernel norm minimization and one dimensional guided filtering, which realizes high-speed parallel processing of the two filtering methods. The experimental results show that the proposed infrared video acquisition system can increase the roughness, RMS contrast and information entropy to 17.4 times, 3.15 times and 2.16 times of the original image, respectively, and significantly improve the visual effect and detail performance of the infrared image. The ZYNQ-based design is not only highly integrated, but also has a fast processing speed to meet the needs of real-time processing. Compared with the traditional PC platform, the system has significant advantages in portability, power consumption and cost, and provides an efficient and reliable solution for the practical application of infrared video acquisition technology. |
