摘　　要：本文提出了一种基于柱状全景图的空间漫游视图拟合算法。其核心是基于固定点柱状全景图之间的空间关系并通过图像拼接技术和图像混合技术生成任意视点下图像。为实现漫游行进中视图信息的合理过渡,设计了固定视点柱状全景图分割后各部分的图像映射关系。实验证明该漫游策略可以满足虚拟漫游的实时性要求,同时具有规模扩展性。This paper proposes a fitting algorithm of walkthrough view based on the spatial relations of diverse fixed views and image mosaic technology and image blending technology which enable smooth interaction between user and virtual environment. This algorithm naturally divided each cylindrical panorama into parts so that the design mapping relation- ship of each part of all panoramas located in four vertexes. The image projection transformation is used to realize the reasonable translation. Experimental result shows that the proposed strategy is fast enough and scalable for real time applications.
