A practical,efficient smooth roaming algorithm based on image distortion for switching viewpoints in panoramic system is presented.The feature extraction method is presented by using SIFT method,the key points are filtered by using the method of dividing the region,and the map relation of key point set is established.Then,the Delaunay triangulation of feature point set is constructed and the affine transformation parameters of corresponding region on the basis of Delaunay triangulation are evaluated.Finally,the intermediate images after interpolating the images are produced for smoothly switching.The experiments show the problems above have been well resolved.The method implements the automation corresponding relation of feature point set and enhances the interactive and immersion of panoramic system.The result shows the method is practical and highly efficient,and it has better adaptive for the images influenced by some uncertain factors.
