中文摘要: 介绍了基于视频拼接技术的无人实况转播系统的实现. 首先对图像进行预处理，然后使用SURF算法对视频图像进行图像配准拼接，并对拼接图像进行融合. 提出了一种基于运动前景提取的全景视频中热点区域确定方法，该方法可平滑追踪热点区域进行提取实现实时转播. 本系统的实现节省了视频直播过程中的人力财力.
Abstract:This paper introduces the live broadcasting system based on video mosaic technology. First, it makes the image preprocessed. After the image pre-processing of video images this paper uses SURF algorithm for image registration stitching on the mosaic image fusion. This paper proposes a method for determining which based on foreground extraction. This method can track hot region smoothly and achieve real-time broadcasting. The system saves a lot of human and financial resources.
