Title:
IMAGE BACKGROUND GENERATION METHOD AND APARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/015868
Kind Code:
A1
Abstract:
The present application belongs to the technical field of image processing, and discloses an image background generation method and apparatus, and a computer-readable storage medium. An image processing device first obtains description information of a simulated scene corresponding to a target scene and camera parameters of a camera deployed in the target scene, and then performs projection transformation on a three-dimensional scene model in the description information by using the camera parameters of the camera to obtain an image background corresponding to the camera. The image background is an image from the viewing angle of the camera, which is consistent with both the viewing angle and visible region of a real image captured by the camera. In a composite image obtained after replacing the background in the real image captured by the camera with the image background, the foreground and the background always match, and the imaging effect of the composite image is better.
