摘要： 基于配置静态存储方法的全景应用模式已能较好地满足一般的全景浏览应用要求.但在更新频繁、交互量大、场景数多的环境下，此方法容易造成维护困难、服务器数据量激增等问题.针对在不同场景图像配置中存在重复的静态内容这一问题，提出了一套具有普适性和可移植性的全景配置文件动态生成方法：提炼静态内容，存储动态内容，并根据不同场景的请求参数动态生成配置文件.经实验对比，相较配置静态存储方法，动态生成方法显著减少了服务器文件数量，在传输时间、可维护性与浏览器缓存利用方面均优于传统方案.

Abstract: The application model based on static storage of the panoramic configuration file meets normal requirements. But in systems which demand frequent update, complex interaction and contain large number of scenes, it may lead difficulties in system maintenance as well as a sharp rise of the configuration file number. Since some static configuration contents appear repeatedly in different scenes' configuration files, we propose an improvement method by extracting the static content from the configuration file, storing the dynamic content in database and creating configuration file based on the parameters about the current scenes. Experimental results show that the dynamic generation method can remarkably reduce the number of files, and is superior to static storage method in transmission time, maintainability and cache use.
Key words: panorama    configuration    dynamic generation
