从低分辨率图像序列重构高分辨率图像

High-resolution image reconstruction from a low-resolution image sequence

从多视图几何技术出发,利用透视同伦变换技术、切点累积生成和运动估计及几何校正等技术将一组真实场景照片重构出一幅高分辨率的柱面全景图。由此研发的交互式全景漫游生成系统ADPW具有全景图生成、基于超媒体架构的多媒体信息融合、交互式全景漫游、发行(脱离系统运行)等功能,不仅实现了高度真实感的多媒体实时交互漫游,还可以发行相应的虚拟场景浏览器,脱离ADPW开发工具单独运行,可作为用户二次开发工具以便用户进一步开发。

This paper reconstructs some natural photos to an high-resolution panoramic image based on cylindrical coordinates using the persective homotopy tansformation, the tangent points cumulation, motion estimation and geometric rectification technology of multiple view geometry. ADPW, the developed interactive panoramic warping developing tool can reconstruct high-resolution panoramic image, stitch up multimedia, interactive warp and publish browser. The ADPW panoramic warping technology can warp real-time and smoothly and have high quality like photo. This tool can be used to realize applications of virtual reality. And the published warping browser can run by itself without ADPW, which is more helpful to research other software.
