Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 As shown, the key equipment required by the present invention includes: stereo DLP projector, active network infrared camera, metal curtain, programmable active shutter glasses, surround sound stereo earphones. Install the projector on the ceiling or on the wall in the theater; with surround sound stereo headphones, users can hear the stereo sound generated based on their position, and there is no sound interference between users to create a sense of immersive shock . An infrared camera device that captures user location information is installed on the wall opposite the metal screen.

[0047] Such as figure 2 As shown, take the dual-picture display as an example. Operation process of the present invention is:

[0048] (1) The infrared camera obtains the location information of the audience and tracks them in real time;

Abstract

The invention discloses a multi-user clustering and viewpoint calculating system and method based on multiple three-dimensional pictures. The system comprises an infrared capturing module, a position mapping module and a real-time clustering module, wherein the infrared capturing module is used for obtaining the position information of a user, and tracking users in real time, the position mapping module is used for mapping physical coordinates of the infrared capturing stage to the virtual space coordinates, and the real-time clustering module performs real-time dynamic clustering on virtual space users according to user distribution characteristics, takes the central position of a clustering block as viewpoint information of the users, and provides data for follow-up picture rendering. Under the condition that the number of audiences exceeds that of displayed pictures of the system, the audiences with the large position difference can watch the three-dimensional pictures of different viewpoints on the same projection screen, the audiences at the close positions can watch the three-dimensional pictures of the same viewpoint on the same projection screen, and the users can creatively feel stronger and more natural immersed and realistic experience.

Description

technical field [0001] The invention relates to a multi-user clustering and viewpoint calculation system and method based on three-dimensional multi-picture. Background technique [0002] In most stereoscopic display devices currently on the market, when multiple users watch the same screen display, they tend to see the same picture. That is, when there is an object moving on the screen of the display, the moving direction of the object they see is also consistent. But in the real world, when an object "flies" towards us, the trajectory of the object seen by people at different viewing angles is actually different. In response to this problem, Samsung launched the first curved OLED TV 55S9C in the second half of 2013, which realized 3D intelligent dual-picture, allowing two viewers to watch different content at the same time, while using the matching 3D glasses and built-in stereo Headphones to watch and listen to two different screens. In addition, Sony has also proposed...
