| 摘 要： | 随着图像处理技术及传感器技术的不断发展,高清数字图像取代模拟图像成为一种趋势。设计了一种基于HDSDI技术的高清图像处理系统,可通过FPGA+DSP架构对1080P全高清图像进行采集和字符叠加,并实时进行目标提取和偏差量计算。叠加视频可通过DVI数字接口或模拟接口实时显示。利用图像高分辨率特性,系统可实现运动目标精确跟踪。

| Abstract: | The high-definition image replaces analogue image to become a kind of trend with the development of image processing tech- nique and sensor technique. A high-definition image processing system is designed based on HD-SDI technique. The system can acquire 1080P high-definition image and make character composition through the structure of FPGA and DSP, and it can extract target and compute deviation in real-time. The composition video is displayed in real-time through DVI digital interface or analogue interface. The system can track moving target accurately with the high-resolution characteristic of images. |
