Problems solved by technology

In the process of realizing this, there are at least the following problems in the prior art: since the existing video resources and content are generally still at the 2D level, it is necessary to construct a virtual scene for it when playing in a virtual reality device
However, this kind of processing method is relatively rough. The virtual environment cannot create a suitable atmosphere according to the changes of the movie, and the constructed virtual scene cannot bring a good sense of immersion in watching videos.

Embodiment 1

[0060] Such as figure 2 Shown, a kind of video playing method based on virtual reality technology comprises the following steps:

[0061] S1: Construct a video playback scene, the video playback scene includes a first area for playing video and a second area around the first area for providing a virtual scene;

[0062] S2: play the video in the first area;

[0063] S3: Extract the theme color in the video and render the virtual scene based on the theme color.

[0064] Such as image 3 As shown, in this embodiment, in order to provide user experience, the video playback scene not only includes a first area for playing video, but also includes a second area for providing a virtual scene, and the second area is located around the first area, The first area partially covers the second area.

[0065] Rendering the virtual scene based on the theme color can ensure the consistency of the video and the surrounding virtual scene, so that the virtual environment can create a suitab...

Embodiment 2

[0067] A video playback method based on virtual reality technology, comprising the following steps:

[0068] S1: Construct a video playback scene, the video playback scene includes a first area for playing video and a second area located around the first area and used to provide a virtual scene;

[0069] S2: play the video in the first area;

[0070] S3: During the video playback process, the theme color in the video is extracted at predetermined intervals, and the virtual scene is rendered, and the predetermined time is 3s. Such as Figure 4 shown, including:

[0071] S301: During the video playing process, intercept a frame from the video at the first time every interval as a key frame of this time period;

[0072] S302: Load the image read into the key frame;

[0073] S303: Scale down the image of the key frame, and list the colors of all pixels in the reduced image and the number of occurrences of the corresponding colors;

[0074] S304: Randomly select X colors from ...

Embodiment 3

[0082] Others are the same as embodiment 2, such as Figure 5 As shown, the following steps are also included:

[0083] S306: Implement rendering in a gradient manner.

[0084] Gradual replacement of the virtual scene can ensure the continuity of the virtual scene, prevent the impact of the sudden change of the virtual scene on the user's viewing of the video, and avoid the abruptness of the viewing process. At the same time, the gradation process can be from bright to dark and then from dark to bright. This gradation process can ensure that the virtual scene is switched in a fade-in and fade-out manner, which improves the user's viewing experience.

Abstract

The invention discloses a video playing method based on the virtual reality technology. The method comprises the following steps: constructing a video playing scene, wherein the video playing scene comprises a first area used for playing a video and a second area located on the surrounding of the first area for providing a virtual scene; playing the video in the first area; and extracting a theme color in the video and rendering the virtual scene based on the theme color. The invention further discloses a video playing system based on the virtual reality technology. According to the video playing method and system based on the virtual reality technology in the invention, the theme color in the video is extracted to render the virtual scene beyond the video so as to create an immersive feeling through the light effect, therefore the immersion of users when watching videos in virtual reality can be enhanced, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of video playing. More specifically, it relates to a video playing method and system based on virtual reality technology. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) technology is an emerging technology, which integrates computer graphics technology, computer simulation technology, sensor technology and display technology, etc. The virtual information environment of information fusion and the unification of interactive three-dimensional dynamic vision and physical behavior can enable users to have an immersive sense of immersion and have a perfect interaction ability with the environment. [0003] The so-called sense of immersion can also be called the sense of spatial presence, which is usually defined as "when media users perceive the media content as a 'real' thing, the media user will feel that he is in the media in the sense of space. feeling in the environment"....
