摘要
给出了一种FPGA和DSP为主架构的实时视频图像处理平台。其中,以EP20K600EBC652-2X为核心处理器完成了实时图像消旋系统设计。提出一种有效的实时消旋算法。该平台利用旋转算法将原图像反向旋转相应的角度,它将抖动旋转的图像反向旋转相应角度,再用双线性插值方法进行重采样,达到了实时稳像的良好效果。阐述了这一图像消旋的算法原理及其优化设计,介绍了DSP以及FPGA的相关软硬件设计技术。
A DSP and FPGA-based architecture of the video image real-processing platform is proposed in this paper, EP20K600EBC652-2X-core processor is used to implement real-time image-rotation elimination function. The algorithm for effective rotation elimination is described in this paper. The rotated image is reversed in a corresponding angle, and then the bilinear interpolation method of resampling is used. The real-time image stabilization is obtained finally. The analysis and optimization of the algorithm and the system design, including hardware and software of DSP and FPGA. are given in this paper.
