Method for generating spherical panorama based on full frame image

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 ...

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 panoramic image is not as good as that of the drum image, and the drum image taken by the pan-tilt along the horizontal rotation cannot generate a seamless global panorama, because the vertical angle of view (VFov) of the sigma lens used to shoot the drum image is only 180 degrees, which means that the system error of the lens and the camera and the measurement error of the photographer when shooting will cause a small amount of information loss at the top and bottom of the panoramic image

[0004] The existing panoramic image generation methods have the disadvantages of complex shooting of original images, low degree of automation in the stitching process, long time-consuming, and low definition.
