摘要： 针对单视点全景技术在相对拥塞的环境中难以观看到障碍物背后影像的不足，利用单视点空间和视点间的双向过渡链的搭建，构造一个多视点虚拟场景。采用影像匹配、直线提取等图像处理技术手段有效实现视点空间之间的平滑漫游。实验结果表明，该方法能取得较好的视觉效果，在一定程度上提高多视点虚拟场景内漫游的真实感。

Abstract: For a scene which is not open, it is difficult to watch the scene behind the barrier through the single-viewpoints. But the cross-cutting in the multi-viewpoints space can make up for its shortcomings. Panoramic technology in single technology is mature. Under such circumstances, the smoothing browser between all viewpoints become the key. This paper describes a construction mind of multi-perspective of the virtual scene. It designs a smooth roaming approach in the virtual space based on multi-viewpoints. Using the image-matching and the line-extraction method, it implements a single-view panoramic and transition-image-between-viewpoints generation platform, as well as the multiple-viewpoints scene browser platform, and gets a good visual effects in the smooth transition between the viewpoints.

Key words: panoramic image, multi-viewpoints, smoothing browser
