Title:
METHOD AND SYSTEM FOR UNWRAPPING PANORAMIC IMAGE
Document Type and Number:
WIPO Patent Application WO/2018/076663
Kind Code:
A1
Abstract:
Provided in the present disclosure are a method and a system for unwrapping a panoramic image. The method comprises: dividing equally and longitudinally, by an equal latitudinal difference N-1, a spherical panoramic image into N spherical regions, and respectively projecting the N spherical regions to obtain an unwrapped latitudinal view; dividing equally and latitudinally, by longitudinal difference M-1, the unwrapped latitudinal view into M spherical regions, and respectively projecting the M spherical regions to obtain an unwrapped longitudinal view; uniformly transferring the lower half of the hexagon of the unwrapped longitudinal view to the upper half of the hexagon of the unwrapped longitudinal view and splicing same to obtain a plane panoramic image. In the method and system for unwrapping a panoramic image provided in the present disclosure, the size of the unwrapped two-dimensional image is smaller than the size of the image unwrapped using the popular panoramic image unwrapping method, while guaranteeing that the unwrapped plane images have identical quality, achieving purposes of saving memory and reducing bandwidth.
