Algorithm of automatically stitching of panoramic image based on gray accumulation estimate

Whether the panorama was cylindrical or spherical,much manual operation was necessary to use existing stitching method,which was inefficient and expensive.In order to realize stitching automation,a new algorithm was presented,where the photos were projected with a spherical mapping according to the textural center.After the image with superposed bands being after projected and surveyed,and then taking the gray accumulation average of the superposed differentiating image as an estimate parameter,the optimal position of the textural center was calculated and the panoramic image was generated with this position as stitching condition.This algorithm was suitable for stitching of spherical and cylindrical panorama.This algorithm could make the program completely automatic for the stitching of panoramic image,so that decreased its processing cost.
