Method and device for converting traditional two-dimensional square video into 720 panoramic stereoscopic video

Abstract

The embodiment of the invention provides a method and device for converting a traditional two-dimensional square video into a 720 panoramic stereoscopic video, the inner surface of a 720 capsule-typescreen is used for providing continuous images with the viewing angle ranging from 180 degrees to 360 degrees in the horizontal direction, the 720 capsule-type screen comprises a cylindrical part andat least one end part, and the method comprises the steps of: acquiring a video frame image of a to-be-played traditional two-dimensional square video; performing 3D conversion on the video frame image to obtain a video frame image with a stereoscopic visual effect; performing UV conversion on the video frame image with the stereoscopic visual effect to obtain a video frame UV map; and according to the video frame UV chartlet, generating a video which is played on the 720 capsule-type screen and has a stereoscopic visual effect. According to the scheme, a traditional two-dimensional square video can be converted into a video which has a stereoscopic visual effect and can be watched by audiences through the inner surface of the 720 capsule-type screen, and the audiences can obtain good panoramic immersive video watching experience.

Description

technical field [0001] The embodiments of the present application relate to the field of display technology, and in particular to a method and a device for converting a traditional two-dimensional square video into a 720 panoramic stereoscopic video. Background technique [0002] In order to improve the comfort of viewers watching videos, images can be displayed through 720 capsule screens, in which the 720 capsule screens can provide continuous images with a viewing angle of 180 degrees to 360 degrees in the horizontal direction, and the viewers in the same row watch the 720 capsule screens. The inclination is relatively consistent, and the audience can watch images through the 720 capsule screen with better comfort. [0003] 3D video is a video with a stereoscopic visual effect, and the audience can clearly feel the difference in the distance between different things in the 3D video and themselves when watching the 3D video. Due to the high production cost of 3D video and...

Problems solved by technology

Due to the high cost of 3D video production and the immaturity of early 3D video production technology, most of the current videos, especially some early classic movies or TV series, are not 3D videos.

At the same time, due to the difference between the structure of the 720 capsule screen and the structure of the flat screen, when non-3D video is displayed on the above-mentioned 720 capsule screen, the objects in the displayed picture not only cannot present a three-dimensional state, but also in the displayed picture. things are also distorted, resulting in a poorer experience for the viewer
