Video reconstruction method, system, device, and computer readable storage medium

One or more computer readable storage media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• obtaining an image combination of multi-angle free-perspective video frames, parameter data corresponding to the image combinations of the video frames, and position information of a virtual viewpoint based on a user interaction, wherein the image combinations of the video frames includes multiple groups of texture images and depth maps with multiple synchronized angles and having correspondence relationships;
• selecting texture images and depth maps of corresponding groups in the image combinations of the video frames at a time moment of the user interaction according to a preset rule and based on the position information of the virtual viewpoint and the parameter data corresponding to the image combinations of the video frames;
• and
• combining and rendering the texture images and the depth maps of the corresponding groups in the image combinations of the video frames at the time moment of the user interaction, based on the position information of the virtual viewpoint and parameter data corresponding to the depth maps and the texture images of the corresponding groups that are selected in the image combinations of the video frames at the time moment of the user interaction, to obtain a reconstructed image corresponding to a position of the virtual viewpoint at the time moment of the user interaction.

A system comprising:

• one or more processors;
• memory;
• an acquisition unit stored in the memory and executable by the one or more processors to obtain an image combination of multi-angle free-perspective video frames, parameter data corresponding to the image combinations of the video frames, and position information of a virtual viewpoint based on a user interaction, wherein the image combinations of the video frames includes multiple groups of texture images and depth maps with multiple synchronized angles and having correspondence relationships;
• a selection unit stored in the memory and executable by the one or more processors to select texture images and depth maps of corresponding groups in the image combinations of the video frames at a time moment of the user interaction according to a preset rule and based on the position information of the virtual viewpoint and the parameter data corresponding to the image combinations of the video frames;
• and
• an image reconstruction unit stored in the memory and executable by the one or more processors to combine and render the texture images and the depth maps of the corresponding groups in the image combinations of the video frames at the time moment of the user interaction, based on the position information of the virtual viewpoint and parameter data corresponding to the depth maps and the texture images of the corresponding groups that are selected in the image combinations of the video frames at the time moment of the user interaction, to obtain a reconstructed image corresponding to a position of the virtual viewpoint at the time moment of the user interaction.
