Multi-user clustering and viewpoint calculating system and method based on multiple three-dimensional pictures

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...

AI Technical Summary

Problems solved by technology

[0004] (1) Audiences in different positions can only see the stereoscopic picture of the same viewing angle on the same projection screen;

[0005] (2) The viewer can see several pictures with limited fixed viewpoints, but the pictures are pre-rendered, the storage and communication volume is large, and the number of viewers is small; or the viewing area is divided in advance, which lacks a sense of reality

[0006] (3) During the viewing process, the audience's activity range is small and the location information is single
