针对鱼眼图像畸变大、表示的场景信息不直观等特点，本文提出了一种基于视点纠正的鱼眼图像场景化漫游方法。该方法以鱼眼图像所表示的半球空间为观察对象，通过视点的转移在半球空间进行漫游，以对不同区域内的场景信息进行直观的观察。采用鱼眼图像校正算法为基础建立鱼眼镜头的球面映射模型，通过映射关系对以视点为中心的观察区域进行实时校正，当视点变化时对校正后的可视区域进行实时显示从而实现漫游。实验结果表明，通过本文算法能够实现鱼眼图像所表示半球空间的实时漫游，且漫游时显示的校正图像满足直线约束标准。

Since significant distortion exists in fisheye image and it is non-intuitive to represent scene information, a scene roaming method of fisheye image based on viewpoint correction is proposed in this paper. In this method, the hemisphere space represented by fisheye image is taken as the viewing target, through transferring the viewpoint to roam in the hemisphere space, so that different information in the scene is observed intuitively. In this method, a spherical mapping model is build based on fisheye image correction method, and real-time correction of the viewpoints centered at observation area is realized based on the mapping relationship. The roaming is realized through displaying the viewing area after correction in real time during viewpoint changing process. Experimental results show that, real time roaming of spherical space represented by fisheye images can be achieved through the method, and the images displayed during roaming process satisfy the line restriction rule.
