Abstract

The invention discloses an image reconstruction method and device, a computer readable storage medium and a processor. The method comprises the following steps: detecting an interactive operation on an operation interface, and obtaining a target position of a virtual viewpoint after displacement on the operation interface; controlling the virtual viewpoint to be transited from the target position to a preset position, wherein the preset position is a camera position coinciding with the spatial freedom degree position of the virtual viewpoint; and processing the image of which the virtual viewpoint is located at the preset position by using an image deformation model to obtain a reconstructed image. According to the invention, the technical problem of low timeliness when the image is reconstructed at the virtual viewpoint is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for reconstructing an image, a computer-readable storage medium and a processor. Background technique [0002] Currently, a user uses gesture interaction to determine a virtual viewpoint position for viewing video images on a terminal. During the viewing process, due to the lack of computing resources of the terminal or poor video quality, when the user stays on the virtual viewpoint for a long time to watch, the video freezes, resulting in poor timeliness when reconstructing images from the virtual viewpoint. [0003] For the aforementioned technical problem of poor timeliness when reconstructing an image from a virtual viewpoint, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a method, device, computer-readable storage medium, and processor for reconstructing an image, so as to ...
