摘　　要：随着倾斜摄影测量技术的飞速发展,三维实景建模技术的应用需求量越来越大。以倾斜摄影测量建模为基础,采用OSG三维渲染引擎设计与创建图形窗口,通过软件研发实现人机交互自助漫游应用功能。本软件可由用户自行设定路径,模型浏览更为顺畅,与传统漫游路径设置相比,操作更为简单、便捷、直观,能进一步增强游客对实景三维模型浏览沉浸感的情感体验,通过自助漫游操作,感受漫游视点运动自然流畅的真实感。With the rapid development of the oblique photogrammetry technology,the application of three-dimensional models more and more popular. The article has developed a software which utilizes OSG three-dimensional rendering engine to design and create graphic windows based on oblique photogrammetry. The software will realize the self-service roaming of human-machine interaction. It can be used to set users＇ own paths,and make the browsing of models get smoother. Compared with the traditional roaming path setting,software operation in the current study is simpler,more convenient and intuitive. It can further enhance people＇s feeling of immersion in the three-dimensional model browsing. The self-service roaming is easy to operate,rendering roaming viewpoints move visually and naturally.
