摘　　要：针对日面活动的多样性和复杂性,采用高性能的数字视频处理技术——达芬奇技术设计了日面活动图像处理与识别系统(SIPRS)。首先从SIPRS的系统架构出发,对系统的硬件设计进行了分析,特别是对DM6437与数字相机MDC1004之间的接口进行了详细的分析;在软件上按系统功能需求规划出八个核心任务,实现了SIPRS基于Web的远程系统配置及日面活动图像的预处理、处理和识别功能。整个系统采用高性能数字媒体处理器、优化的实时操作系统和优化的图像处理与识别算法,完全满足太阳望远镜终端实时图像处理的要求。This paper designed an solar activities image processing and recognition system （SIPRS） for the diversity and complexity of the solar activities based on high-performance digital video processing technology： DaVinci technology. First, analyzed system hardware design, particularly analyzed the interface between digital cameras MDC1004 and DM6437. Second, abstracted eight core tasks according to the demand of the system in system software design. Third, implemented the Webbased remote system configuration and the image preprocessing, processing and recognition on solar activities for the SIPRS. Experiments show that by using a high-performance digital media processor, optimized real-time operating system, and optimized algorithm of image processing and recognition, the entire system can perfectly meet the requirements of the real-time solar image processing.
