Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] A sample image in the present invention is given in FIG. 1 . A circular fisheye image captured by a fisheye lens is shown in Figure 101. This type of fisheye image is widely used, but the CCD utilization rate is relatively low, and CCDs in black areas other than circular areas are not used. Therefore, in order to improve the utilization of CCD, lens manufacturers have introduced fisheye images of sigma and fullframe lenses. The image shown in Figure 102 is a drum-shaped image, and the image shown in Figure 103 is a full frame. For images, the method of the present invention can automatically generate a cube panoramic image of required size for multiple circular fisheye images, drum-shaped images, and full-frame images.

[0015] First, the user shoots multiple fisheye images in a specified order through the fisheye lens camera, so that the center vecto...

Abstract

A method of using fisheye image to generate stereoscopic panorama includes shooting out a numbers of fisheye image by fisheye camera according to specified sequence, confirming character point air at overlapped region of adjacent images and setting-up stereoscopic space model as per obtained matching point pair, calculating out position of original image on stereoscopic space and resampling original fisheye image according to calculated out parameter in order to generate out stereoscopic panorama.

Description

technical field [0001] The invention relates to a method for generating a cube panorama, in particular to a method for automatically stitching together a plurality of pictures collected by a fisheye lens to form a cube panorama image. Background technique [0002] Panorama is an interactive virtual scene representation method, which reproduces the three-dimensional scene based on image rendering, and can use the panorama player to realize the roaming of the virtual scene and bring the real scene experience to the user. With the development of technology, panoramas are no longer limited to a single mode. According to the different display methods of panoramic scene projection, it can be divided into: cylindrical panorama, spherical panorama, and cubic panorama. Cube panorama assumes the scene as a cubic space, and the output is an image with an aspect ratio of 6:1 on the front, back, left, right, upper, and lower sides. The viewpoint is at the center of the cube, full view....
