Abstract

The invention relates to the technical field of 3D display, and discloses a method for displaying a bullet screen in a 3D video. The method comprises the steps: providing a 3D bullet screen; and embedding the 3D bullet screen into the first 3D video. According to the method, the bullet screen in the 3D form can be embedded into the 3D video. The embedding mode of the 3D bullet screen is flexible, and the position can be adjusted along the bullet screen moving path so as to present a good visual effect to a user. The invention further discloses a device for displaying the bullet screen in the 3D video and a 3D display device.

Description

technical field [0001] The present application relates to the technical field of 3D display, for example, to a method and device for displaying barrage in 3D video, and a 3D display device. Background technique [0002] At present, 3D display technology has become a research hotspot in imaging technology because it can present a lifelike visual experience to users. [0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in related technologies: there is no solution for adding barrage to 3D video in 3D display devices, which reduces the fun of user interaction. [0004] This background art is only for the convenience of understanding related technologies in this field, and is not regarded as an acknowledgment of prior art. Contents of the invention [0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. This sum...
