Abstract

The invention discloses a method for quickly stitching a panoramic image of a cube. The method herein includes the following steps: arranging a panoramic camera, simultaneously photographing a front space in the front, rear, left, right, above and below directions; calibrating the panoramic camera, acquiring a distortion correction parameter, further acquiring a linear transformation parameter and a cropping parameter of respective image; photographing scenes by using the panoramic camera, firstly conducting distortion correction on a camera lens by using the distortion parameter, then conducting rotation transformation and transverse transformation on each image by using the linear parameter; cropping the obtained 6 images in the centers in accordance with the cropping parameter, such that the 6 images are approximately the same in size and have a visual angle of 90 degrees in the horizontal direction and the vertical direction, and eventually, separately placing the squares which are obtained by cropping the 6 images at places where the panoramic image of a plane cube and the photographing camera correspond. According to the invention, the method only requires one time calibration process, can repeatedly use calibration parameters, simplifies the stitching process, accelerates the stitching speed, and saves great stitching time.

Description

technical field

[0001] The invention relates to the field of image splicing, in particular to a fast splicing method for cube panoramas. Background technique

[0002] A panorama refers to a full-view image with a horizontal viewing angle of 360 degrees and a vertical viewing angle of 180 degrees. According to the display mode, panoramas are mainly divided into spherical panoramas, cylindrical panoramas, and cubic panoramas. The current mainstream panoramas generally use spherical panoramas or cubic panoramas as sources when displaying them, but the splicing method mainly adopts the splicing and fusion method of spherical panoramas. To adopt the cube panorama display method, the spherical panorama generated by splicing needs to be converted into a cube panorama and then displayed. The existing panorama stitching process mainly includes image acquisition, lens distortion correction, image matching, image stitching, image fusion and other processes. There are mainly the foll...
