摘　　要：该文对鱼眼相机拍摄的照片建立了一种可校正的鱼眼镜头抛物面模型和一组鱼眼透视约束条件 对于一个场景 ,只需前后拍摄两幅鱼眼照片并给出其结构草图 ,就可以利用局部高斯加权的算法提取整个场景框架 ,从而恢复场景的三维模型 以此模型为基础 ,不仅可以实现全景漫游 。An improved parabola model and a group of restricted projecting conditions of fish-eye lens are proposed. For a scene, only two fish-eye photos taken forward and backward, along with the corresponding drafts given in advance to predict the horizontal and vertical silhouettes of objects, are enough to get the whole structure and 3D model of the scene by using an algorithm based on Gaussian local weight. Based on this model, not only the panorama can be acquired, but also the 3D view at any position and any direction can be got. This approach greatly simplifies the complicated calculation for photos taken by a camera with normal lens.
