The invention puts forward a fisheye image panorama generation method based on a cylindrical model by aiming at an image shot by a fisheye panorama camera at a specific angle on the basis of comprehensively researching an existing panorama image generation technology and a fisheye image correction technology. The innovation point of the method is that only a single monitoring image collected by the fisheye panorama camera at an overlooking or looking-up angle needs to be used for generating the panorama image through processes including image preprocessing, image correction processing and thelike. By use of the method, a complex image collection process and a complex operation of generating the panorama image by splicing multiple images are omitted, and the method has the advantages of low manual cost, high processing speed, simpleness in operation, high practicality and high instantaneity. 本发明在综合研究现有全景图像生成技术和鱼眼图像校正技术的基础上，针对鱼眼全景摄像机在特定角度下拍摄的图像，提出种基于柱面模型的鱼眼图像全景生成方法。该发明的创新点在于只需要利用鱼眼全景摄像机在俯视或仰视角度下采集到的单幅监控图像，通过图像预
