Abstract

The present disclosure discloses a virtual cinema and an implementation method thereof. The implementation method of the virtual cinema comprises: arranging a virtual screen, and playing a video content thereon; and projecting ambient light varying with the video content around the virtual screen. By projecting ambient light varying with the video content around the virtual screen while displaying the video content to the user through the virtual screen, the sense of reality is enhanced, thereby solving the problem that the user experience is affected because the ambient light is not considered enough in the existed virtual cinema.

Claims

1. An implementation method of a virtual cinema, the implementation method applicable to a virtual reality device, the implementation method comprising:

arranging a virtual screen with a Unity3D technique;

providing a projector on the virtual screen and setting a direction of the projector to project around the virtual screen, via a projector component provided by Unity3D;

playing video content on the virtual screen;

obtaining data of each frame of image of the video content in real time when the video content is playing on the virtual screen;

obtaining ambient light data corresponding to the obtained data of each frame of image in real time;

applying the obtained ambient light data to the projector; and

projecting, via the projector, ambient light that varies with the video content around the virtual screen.

2. The implementation method of a virtual cinema according to claim 1, wherein obtaining ambient light data comprises performing a Gaussian blur algorithm to process the data of each frame of image into data including only colors, which serves as the ambient light data.

3. A virtual cinema applicable to a virtual reality device, the virtual cinema comprising a virtual screen, an ambient light obtaining module, and a projection module, the virtual screen arranged with a Unity3D technique and configured to play a video content, the ambient light obtaining module connected to the virtual screen and the projection module, the ambient light obtaining module configured to obtain data of each frame of image played by the virtual screen in real time, obtain ambient light data corresponding to the obtained data of each frame of image played by the virtual screen in real time, and transmit the obtained ambient light data to the projection module, and the projection module implemented using a projector component provided by Unity3D and configured to provide a projector on the virtual screen, set a direction of the projector to project around the virtual screen, and apply the obtained ambient light data to the projector, the projector configured to project ambient light that varies with the video content around the virtual screen.

4. The virtual cinema according to claim 3, wherein the ambient light obtaining module is configured to perform a Gaussian blur algorithm to process the data of each frame of image into data including only colors, which serves as the ambient light data.
