Embodiment Construction

[0068] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0069] The multi-angle free viewing angle data is data that can support the user to switch viewing angles.

[0070] The multi-angle free-view data can include texture maps collected by multiple cameras, all camera parameters, and the depth map of each camera. The generation process of multi-angle free-view data can usually include multi-camera video capture (Multi-camera Video Capturing), camera internal and external parameter calculation (Camera Para...

Abstract

The embodiment of the invention provides a multi-angle free view angle data generation method and device, a medium and equipment, and the method comprises the steps: obtaining a plurality of synchronous images, and enabling the viewpoints of the plurality of images to be different; determining a virtual path, wherein the virtual path is a set of viewpoints for watching the to-be-watched area; pre-processing the plurality of images according to a virtual path and the viewpoint of each image in the plurality of images to obtain a pre-processed image set consistent with the virtual path; and generating multi-angle free view angle data based on the preprocessed image set. According to the technical scheme, the image quality can be guaranteed when the viewing angle is adjusted for viewing.

Description

technical field [0001] The invention relates to the field of data processing, and in particular to a method and device, medium and equipment for generating image data with multiple angles of freedom. Background technique [0002] Image data is data that supports image display for users to watch. In an image data generation method, the image data only supports users to watch from one viewing angle, the user cannot adjust the viewing angle, and the user experience needs to be improved. [0003] One way to provide multi-angle viewing is to shoot with multiple cameras to obtain multiple images with different shooting viewing angles, and perform image reconstruction based on the multiple images to meet the user's requirement for adjusting viewing viewing angles. The data basis for image reconstruction is called multi-angle free-view data. [0004] It is difficult to guarantee the image quality during viewing in the existing viewing angle adjustment method.
