Three-dimensional video streaming media transmission method and visualization method

Abstract

The invention provides a three-dimensional video streaming media transmission method, which comprises the following steps of: S1, collecting original data of a video sensor based on a single-board computer running a Linux operating system, and converting the original data into a media basic stream; and S2, based on a single-board computer running a Linux operating system, carrying out compressed encoding on the media elementary stream to obtain an encoded media elementary stream. S3, based on a web server Nginx deployed in a Linux operating system, sending the coding media elementary stream to the client terminal through a network transmission protocol RTMP; and / or, on the basis of a streaming media server rtsp-simple-server deployed in the Linux operating system, sending the coding media elementary stream to the client terminal through a network transmission protocol RTSP (Real Time Streaming Protocol). Resource occupation can be effectively reduced, time delay is reduced, and transmission efficiency is improved. The invention further provides a three-dimensional video streaming media visualization method.

Description

technical field [0001] The invention relates to the technical field of streaming media playback, in particular to a three-dimensional video streaming media transmission method and visualization method. Background technique [0002] With the widespread application of medium and close-range remote sensing platforms represented by drones and mobile survey vehicles, remote sensing data has developed from static images to dynamic image streams, data expression has expanded from two-dimensional space to three-dimensional space, and data transmission methods have changed from post-event transmission to three-dimensional space. Move toward real-time backhaul. For this type of new 3D image data, the current data return and visualization solutions have problems such as small amount of transmitted data, high delay, low display performance, and poor versatility. [0003] For traditional two-dimensional video streaming media transmission, it is mainly divided into multiple segments in t...

Problems solved by technology

On the one hand, the full-view panorama transmission solution causes a waste of resources, on the other hand, massive data puts enormous pressure on the server; and the massive video stream up to 30 frames per second also brings an extremely heavy burden to the CPU of the client terminal. The fast visualization method cannot adapt to this new type of 3D image data that is dynamic, expressed in 3D space, and returned in real time. The previous fast visualization scheme based on CPU is not competent.
