摘　　要：在采用IBMR的方法构造虚拟环境的过程中,全景图的生成是一个重要的环节.在把用普通数码照相机得到的一组相关照片生成全景图时,需要将照片经过投影、拼接和平滑化等步骤生成一幅全景图像.主要把全景图生成中圆柱面正投影算法进行分析、讨论、归纳、总结,并提出一些新观点.最后验证了此算法及其讨论的正确性.In the course of creating the virtual space based on IBMR, it is very important to create panoramic images. After getting a group of correlative photos from the ordinary numeral camera, we need to project, join and process them in order to get a panoramic image. This paper mainly analyzes, discusses, concludes, and summarizes the algorithm of the cylindersurface direct projection in the process of creating panoramic images. And many new ideas are presented. Finally, validity of the algorithm and discussion is proved.
