Problems solved by technology

In the prior art, because the server encodes the complete point cloud data corresponding to the point cloud media (or the point cloud media segment of the point cloud media), and the data volume corresponding to the complete point cloud data is relatively large, when transmitting the point cloud files, if the network quality is poor, it will take a lot of time to transmit point cloud files with a large amount of data, and there will be delays in reaching the user terminal

Embodiment Construction

[0078] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0079] The embodiment of the present application relates to the data processing technology of point cloud media. Among them, point cloud media is a set of discrete point sets that are randomly distributed in space and express the spatial structure and surface properties of three-dimensional objects or scenes. Each point in the point cloud has at least three-dimensional position information, and may also have color, material or other information depending on the application scenario. Typica...

Abstract

The embodiment of the invention provides a point cloud media data processing method, device and equipment and a readable storage medium, and the method comprises the steps: carrying out the point cloud coding of a target point cloud media according to at least two point cloud density levels, and obtaining at least two point cloud coding files; the point cloud density level is used for representing the media quality of the target point cloud media; generating a file packaging data box of the target point cloud media according to the at least two point cloud density levels and the at least two point cloud coding files; and performing file packaging processing on the at least two point cloud coding files according to the file packaging data box to obtain media file resources corresponding to the at least two point cloud density levels. By adopting the application, the user demand can be dynamically adapted, the point cloud media transmission bandwidth is saved, and the data transmission time is shortened.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, equipment and readable storage medium of point cloud media. Background technique [0002] A point cloud is a group of discrete points distributed randomly in space that express the spatial structure and surface properties of a three-dimensional object or scene. Point clouds are widely used, for example, in virtual reality (Virtual Reality, VR) games, computer-aided design (Computer Aided, CAD), 3D point cloud telepresence, and 3D reconstruction of biological tissues and organs. [0003] At present, for the transmission of point cloud media, the main process is that the server encodes the point cloud media, encapsulates the encoded data stream to obtain the point cloud file, and transmits the point cloud file to the user terminal, and then the user terminal needs to first Decapsulate the point cloud file, and decode the decapsulat...
