摘　　要：三维GIS系统实现了现实世界的虚拟化表达,但是所生成的三维场景缺乏真实感,全景技术的三维再现能力,虽然可弥补三维GIS表达上的缺陷,但是缺乏全局可浏览性。以环拍的图像序列为对象,利用Sift(scale invariant feature transform)算子实现全景图的自动拼接,通过Pano2VR软件实现全景图的操纵配置;结合Skyline三维软件,以福建师范大学为例,实现全景三维校园网络浏览系统。该系统具有良好沉浸性、多角度可浏览性,使用户具有真实的三维视觉体验;实现方式简单、构建快速,也为旅游景点、酒店、房地产等小范围场景的全景三维展示提供借鉴。3D GIS can represent the real world in virtual way, even though it overlooks the sense of reality, while the panoramic image records the real scene but no easy to browse the scenes in whole situation without proper methods. They could be the perfect couple to express our real world. The automatic stitching of panoramic image is achieved based on SIFT （scale invariant feature transform） from the images collected by the ordinary camera. And then the configurations for controls of panoramic image are set by the Pano2VR. Based on the process mentioned above, Fujian Normal University is taken as an example, the panoramic three-dimensional campus web browsing system is realized by combining with the development of the skyline software. The system could give the audience a good 3D visual experience. And the process to construct this system is quickly and simply.
