Title:
IMAGE STITCHING METHOD, DEVICE, TERMINAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/171429
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of image processing. Disclosed are an image stitching method, a device, a terminal, and a storage medium. The method comprises: determining a main posture parameter of a current image on the basis of a first overlapping area in the current image; projecting the current image to a projection screen on the basis of the main posture parameter to produce an initial stitched image; selecting a local overlapping area in a second overlapping area of the initial stitched image; calculating a local posture parameter of a local image area in the current image corresponding to the local overlapping area; and re-projecting the current image to the projection screen on the basis of the main posture parameter and of the local posture parameter to produce a target stitched image. Solved is the problem in which a terminal projects an image merely on the basis of a main posture parameter to produce an initial stitched image, and the main posture parameter may not be suitable for the entire current image, thus resulting in poor overlapping in an overlapping area of the initial stitched image produced by the terminal; and enhanced are image stitching effects.
