Abstract

The invention discloses an image interpolation method and device based on RGBD images and a multi-camera system. The method comprises the steps that camera calibration is conducted on each camera in the multi-camera system; determining an interpolation position of a new camera according to the position information of each camera in the multi-camera system, and calculating a camera pose of the newcamera according to camera calibration data; according to the projection relationship of the cameras and the pose information of each camera, calculating a plurality of initial interpolation images having a one-to-one correspondence relationship with specified images acquired by each camera in the multi-camera system; performing image fusion on each initial interpolation image to obtain a fused interpolation image; and performing pixel completion on the fused interpolation image to finally obtain an interpolation image associated with the new camera. According to the invention, the problem that a multi-view-angle video is easy to have an unsmooth impression during switching of viewing view angles due to the fact that the number of the acquisition cameras is too small is solved.

Description

technical field [0001] The invention relates to an image interpolation method, in particular to an image interpolation method and device based on RGB-D and a multi-camera system. Background technique [0002] Today, multi-camera systems are widely used in 3D reconstruction, motion capture, and multi-viewpoint video capture. The multi-camera system tracks and shoots one or more targets at the same time through multiple different cameras, light sources, storage devices, etc., and the obtained multi-view video can better show the characteristics of the target, which can greatly improve the visual experience of the audience. However, multi-view videos can usually only be viewed at the original viewing angle of the capture camera. When the number of capture cameras is sparse, the switching of viewing angles will cause large content changes, making the user feel stuck. Contents of the invention [0003] In order to solve the problem that multi-view video is easy to get stuck wh...
