Embodiment Construction

[0015] The method for generating a full spherical panorama based on six drum-shaped images in the present invention establishes a complete space model—a three-dimensional spherical space model. First, the real world is mapped to a spherical surface Ω with a finite radius, and then the spherical surface is 0 degrees along its latitude direction, and the two meridian directions are 0 degrees and 90 (or 270) degrees respectively. Decompose and extract to get three circular sub-spheres Ω 1 ,Ω 2 ,Ω 3 , and then extract four secondary sub-spheres from each sub-sphere. Wherein, the centers of the second-level sub-spheres are all on their corresponding longitudes or latitudes, and the angle between the center vectors of adjacent second-level sub-spheres is 90 degrees (assuming that the vector from the center of the sphere to the center of the second-level sub-sphere is the center vector), Adjacent secondary sub-spheres have a certain overlapping area. Analyzing the above 12 second...

Abstract

The present invention discloses method of creating complete spherical panorama based on six drum shaped image frames. The method includes the following steps: the first establishing of three-dimensional spherical space model; taking six drum shaped image frames in specific requirement; the subsequent determining of image frame adjacency relations and optimal point pair set between adjacent image frames; establishing and solving the optimizing equations based on the optimal point pair set; and finally creating the panorama. The present invention can solves the problem of automatically splicing drum shaped image frames and the problem of incomplete top and bottom information to create complete spherical panorama fast.

Description

technical field [0001] The invention relates to a panorama generation method, in particular to a method for generating a full spherical panorama based on six drum-shaped images. Background technique [0002] Panorama technology is an important part of the virtual reality system, it is an image-based rendering technology, because the pixels in the panoramic image are interpolated from the pixels in the specific sample image, so its rendering and The complexity of the image scene is irrelevant, and the realism of the panoramic image is just like a photo. The full spherical panoramic image can be obtained directly with a panoramic image camera, or by installing a special panoramic lens such as a fisheye lens, a sigma lens, a full frame lens, etc. on a digital camera or an ordinary film camera lens, with the assistance of a special panoramic head , to collect images of scenes in different directions in the real world, and then process the above images through special panorama g...
