Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below according to the drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 As shown, a CAVE immersive virtual display system includes an audio control module 100, a video control module 200, an edge fusion processing module 300 and a total control module 400;

[0024] The audio control module 100, the video control module 200, and the edge fusion processing module 300 are respectively connected to the general control module 400;

[0025] The audio control module 100 is configured to centrally cache the audio data to be played, generate an audio stream, import the audio stream into a playlist, and play the data in the playlist according to the instruction of the g...

Abstract

The invention provides an immersive virtual display system and a display method of a CAVE (Cave Automatic Virtual Environment). An audio control module is used for caching audio data to be played and generating an audio stream to form a play list, so as to be convenient for outputting audio data in time; a video control module is used for intensively caching video data once, so as to play video images smoothly and efficiently; an edge melting processing module is used for gripping desktop picture data on a main screen through a master control module, therefore processing time can be saved; furthermore, by adopting multithreading traversal operation and supporting multi-channel simultaneous processing, the processing efficiency can be improved; in addition, by adopting a plurality of correction functions to process, including vertex correcting process, geometrical correction processing and pixel RGB (Red Green Blue) colorful correction, on the one hand, the effect of edge melting can be ensured; on the other hand, the data handling capacity can be reduced, therefore, the system is not limited to single channel projection by a video texture technology, the large screen playing and multi-channel large-screen display can be realized by taking a player fusion technique as edge fuse processing.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a CAVE immersive virtual display system and a display method. Background technique [0002] CAVE immersive virtual display system (Cave Automatic Virtual Environment, virtual reality display system) is based on multi-channel visual synchronization technology, three-dimensional space shaping school CAVE projection system is composed of more than 3 surfaces (including 3 surfaces) hard rear projection A highly immersive virtual presentation environment composed of walls, with a 3D tracker, users can get close to virtual 3D objects in the system surrounded by projection walls, or roam the "real" virtual environment at will. CAVE systems are generally used in high-standard virtual reality system. [0003] However, most of the existing CAVE immersive virtual display systems currently project the video content onto the wall for display in the form of one channel per side, and the...
