Embodiment Construction

[0015] This embodiment is a preferred implementation mode of the present invention, and other principles and basic structures that are the same or similar to this embodiment are within the protection scope of the present invention.

[0016] The present invention mainly synthesizes two-way or multi-way 2D video streams into 3D video streams, please refer to the attached figure 1 , the present invention comprises the following steps when realizing:

[0017] (1), video stream acquisition: In the present invention, the video acquisition module shoots the same scene from different angles of view, wherein the angle of view difference between the left and right angles of view simulates the different pictures seen by the left and right eyes of a person, that is, the simulation from Observe and shoot the same scene at the same time in the direction of the two eyes of a person, and form two channels of left and right video data after shooting. When collecting video streams, if the ID o...

Abstract

The invention discloses a 3D (three-dimensional) stereo video single-file double-video stream recording method. In file recording, the method comprises the steps of: defining the ID of a left video stream as N and the ID of a right video stream as N+1, and synthesizing the two video streams in one video file; in synthesis of 3D video file, the method comprises the steps of: taking the start timestamp of the video file as a uniform reference, and adding a timestamp mark to each video frame of the two video streams such that the video frames corresponding to the left and right video streams have the same timestamp. In the invention, the IDs of the left and right video streams are defined by an odd number and an even number so that the left and right video streams can be automatically identified when played; and moreover, the timestamp mark is added to each image frame by taking the start timestamp of the file as reference so as to achieve accurate time synchronization of the left and right images, obtain strong third dimension of the images and prevent ghost and the like. According to the invention, the file format adopts standard formats such as ASF, MKV, AVI and the like for writing; and when in playing, modification of a player is not required so as to facilitate use.

Description

technical field [0001] The invention discloses a 3D video stream recording method, in particular a 3D stereoscopic video single-file double video stream recording method. Background technique [0002] With the development of computer technology, the way of playing video files has also made great progress, from a single picture to 2D video, and from 2D video to 3D video. 3D video has attracted more and more people's attention because of its three-dimensional effect and strong visual impact. There are many existing 3D stereo file formats, which can be roughly divided into single-channel video streams, which are internally separated from left and right, separated from top to bottom, interleaved from left to right, and interleaved from top to bottom to synthesize and encode output, or a single video stream contains multi-view streams inside Encoding, such as the multiview code extension standard of H.264, or two separate files, each containing a way of video stream data. The a...
