Problems solved by technology

[0003] At present, there are many methods for generating panoramic images, but the shooting process is complicated, the stitching is difficult, and the effect is poor.
There are many technical schemes for generating panoramic images, one of which is to generate panoramas based on circular fisheye or drum-shaped images. First, any N circular fisheye (N≥3) or drum-shaped images (N≥4 Zhang), to regenerate a panoramic image, this scheme can effectively solve the problem that the existing algorithm cannot automatically stitch together more than 4 round fisheye images and drum-shaped images, but the disadvantage is that the traditional round fisheye image generation The resolution of the panora

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] figure 1 An example diagram of a sample image involved in the present invention is given. 101 is a full-frame image obtained by using a full-frame lens in Portrait (Portrait) mode, and 102 is a full-frame image obtained in Landscape (Landscape) mode.

[0019] Such as figure 2 As shown, it is an ideal structure of the two-dimensional spherical space model described in the present invention. Its principle and structure are the same as those of the three-dimensional spherical space model, but because the analyzed image is a full-frame image, this type of image information cannot ensure its All the corresponding adjacent spheres have sufficient overlapping areas, so when using this structure diagram, it is possible that only the four secondary sub-spheres of the sub-spheres in the two directions have adjacent matching feature point pairs. , the structu...

Abstract

The present invention discloses method of creating spherical panorama based on full frame images. Through constituting two-dimensional spherical space model in two kinds of space structures, spherical panorama is created with eight, including six horizontal, one overhead and one ground, full frame images, or created with six, including four horizontal, one overhead and one ground, full frame images. According to the characteristics of full frame images, the present invention creates one new optimized formula through parametrizing the full frame images. The method of the present invention has fast image make-up speed, high automation, and high image definition.

Description

technical field [0001] The invention relates to a method for generating a panoramic image, in particular to a method for generating a spherical panorama based on a full frame (fullframe) image. Background technique [0002] Panoramic technology is an image-based rendering technology developed in recent years. The feature of this technology is that its rendering has nothing to do with the complexity of the scene, and it can achieve photo-level realism. Using this technology, the user first takes a group of sample images of a certain scene through photographic equipment, and then stitches the sample images together to obtain the final panoramic image. A spherical model panorama refers to a panorama in which image data is mapped on a spherical surface centered on the viewpoint during playback, and a cube panorama is a panorama in which image data is mapped on a cube surface centered on the viewpoint during playback. A full spherical panorama refers to a panoramic image with a ...
