摘　　要：提出了一种新的动态全景图的生成方法。首先将一系列定点拍摄的照片采用基于粒子群优化(PSO)的多分辨率拼接算法拼接成静态全景图,然后用摄像机拍摄场景中做周期或随机运动的物体,实现视频纹理,最后将视频纹理对准到静态全景图中。自主开发了一种动态全景浏览器。该浏览器除了具有普通全景图浏览器的功能外,还实现了添加、对准以及播放视频纹理的功能,极大地增强了漫游的真实感。A method for the generation of dynamic panoramas was developed. Firstly, employing Particle Swarm Optimization （PSO） based multi-resolution mosaic algorithm, the system generates a static panorama from a series of photographs taken at a fixed position. Then, a video camera is used to capture the periodically or stochastically moving objects in the scene and the system converts these video clips into video texture. Finally, the system registers the video texture with the static panorama and combines them into a compact representation. A novel panorama browser was developed which, in addition to its original functions, implements functions, such as adding, matching and playing video textures. Thus, the browsing visual reality is significantly enhanced.
