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