Abstract

The embodiment of the invention relates to a video coding and decoding method, a device and a video coding and codec; wherein, the video coding method comprises the steps as follows: a first view is used as a reference view and basic layer coding is carried out; furthermore, prediction information is extracted by combining with a second view; furthermore, the second view is reconstructed; the residue value is calculated according to the reconstructed second view and the original second view; when the residue value is more than the valve value, reinforced layer coding is carried out at the same time on the residue value and the prediction information, otherwise the reinforced layer coding is carried out on the prediction information; the reinforced layer codes and the basic layer codes of the first view are multiplexed to gain the coding information; the video decoding method comprises the steps as follows: after de-multiplexing, the basic layer coding information and the reinforced layer coding information are respectively decoded, thus gaining the first view, the prediction information and the residue value; subsequently, the second view is reconstructed. The embodiment of the invention effectively compresses the solid video data, reduces the decoding complexity, is compatible with traditional two-dimensional display, and facilitates the reconstruction of solid view exactly and conveniently.

Description

technical field

[0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a video encoding and decoding method and device, and a video encoding and decoding device. Background technique

[0002] The traditional two-dimensional video is a carrier of plane information, which can only show the content of the scene, but not the depth information of the scene. When human beings watch the surrounding world, they can not only see the width and height of the object, but also can Know the depth of objects and judge the distance between objects or between the viewer and objects. The reason for this three-dimensional visual characteristic is that people use binoculars to watch objects at the same time. Due to the distance between the visual axes of the binoculars, when the left eye and the right eye look at objects at a certain distance, the visual images they receive are different. Two images with different information can create a thr...

Embodiment Construction

[0054] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments.

[0055] Embodiment of video encoding method:

[0056] Such as figure 1 As shown, it is a flowchart of a video coding method in an embodiment of the present invention, which specifically includes the following steps:

[0057]Step 101, two cameras or multiple cameras shoot the same scene from different angles to obtain two views, which are left-eye view and right-eye view respectively;

[0058] Step 102: Select one of the left-eye view and the right-eye view as a reference view to perform base-level encoding, either the left-eye view or the right-eye view, and this embodiment selects the left-eye view as the reference view;

[0059] Step 103: Locally decode the left-eye view encoded by the base layer, and extract prediction information in combination with the right-eye view. The prediction information can be dispa...
