Abstract
The invention is suitable for the field of image processing, and provides a method and device for splicing a panoramic image and a portable terminal. The method includes obtaining a plurality of images used for splicing the panoramic image; unfolding the plurality of images into longitude and latitude images; extracting splicing areas among the plurality of longitude and latitude images to obtain a plurality of splicing areas, and projecting the plurality of splicing areas to a unit ball; extracting a cylindrical surface area corresponding to an area to be spliced on a unit ball surface, and calculating an optical flow field between left and right images of the area to be spliced; and fusing images of the splicing areas according to the optical flow field between the left and right images of the area to be spliced till the images of all the splicing areas are fused, thereby obtaining a panoramic image after seamless splicing. The method for splicing the panoramic image can realize smooth transition between fusion areas, thereby achieving an effect of seamless splicing.
Description
technical field [0001] The invention belongs to the field of image processing, and in particular relates to a panoramic image mosaic method, device and portable terminal. Background technique [0002] Compared with flat images, panoramic images can record 360° images around the shooting location, thereby bringing people a strong sense of reality and three-dimensionality. Therefore, there are broad application prospects in many industries such as film and television, tourism, and real estate. At present, most panoramic images are obtained by splicing multiple images, and more obvious splicing traces will appear in the image splicing area, which seriously affects the quality of the final panoramic image and the visual effect it brings to people. Contents of the invention [0003] The purpose of the present invention is to provide a panoramic image stitching method, device and portable terminal, aiming to solve the problem that there are obvious stitching traces in the image...
