Paper Abstract

A global optimization approach for construction of a 360° full-view panoramic mosaic is presented with global consistency in this paper. There are three primary steps in this approach. The first is a local registration using SIFT. In the second step, an efficient algorithm for finding a global consistent registration of all images is developed. The local registration matrices with the boundary condition are used for computing the initial parameters of the iterative optimization for the global consistent registration, to adjust/reduce the alignment error accumulated by the local registering and stitching of adjacent two images. Lastly, the overlapping areas of the images are stitched by the graph cut algorithm and blended with a multi-resolution method. It is proven by the experiment results in this paper that the presented approach can effectively construct panoramic mosaics with global end-to-end consistency.
