Document Type and Number:
WIPO Patent Application WO/2022/110514
Kind Code:
A1
Abstract:
An image interpolation method and apparatus employing an RGB-D image and a multi-camera system. The method comprises: performing camera calibration on each camera in a multi-camera system; determining an interpolation position of a new camera according to position information of each camera in the multi-camera system, and calculating to obtain a camera pose of the new camera according to camera calibration data; performing calculation according to projection relationships between the cameras and pose information of respective cameras, and obtaining multiple initial interpolated images in one-to-one correspondence with specified images captured by the respective cameras in the multi-camera system; performing image fusion on the initial interpolated images, and obtaining a fused interpolated image; and performing pixel completion on the fused interpolated image, and obtaining a final interpolated image associated with the new camera. The invention solves the problem in which when a multi-view video is recorded using a small number of cameras, a lag occurs easily when a viewer switches between different viewing angles.
