A cave-based fusion system for different-plane perspective correction

Abstract

The invention discloses a different-plane perspective correction fusion system based on CAVE, and specifically relates to the technical field of image processing. The system comprises a server, an operation end, a plurality of processing computers and a plurality of projectors. The plurality of processing computers and the plurality of projectors are mutually connected, the server is connected with the plurality of processing computers through the Internet, and the plurality of processing computers are connected through a synchronous card. The plurality of processing computers are respectivelyresponsible for image information in different projection surfaces to complete perspective correction of the image information in the different projection surfaces. The operation end is connected with the server, is a command input end of a user, and is used for inputting a control command to the operation of the server. According to the system, the perspective corrected graph does not have the phenomenon of deformation distortion, the vertical line in the image can be matched with the image content, the invested capital is small, the operation is simple, the on-line operation is easy, and the practicability is strong.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, the present invention relates to a CAVE-based heteroplane perspective correction and fusion system. Background technique [0002] CAVE is represented by VR-Platform CAVE virtual reality display system. CAVE is an immersive virtual reality display system based on projection, which is characterized by high resolution, strong immersion, and good interactivity. The principle of the CAVE immersive virtual reality display system is relatively complicated. It is based on computer graphics and perfectly integrates high-resolution stereoscopic projection display technology, multi-channel visual synchronization technology, audio technology, and sensor technology. Thus, a fully immersive virtual environment surrounded by three-dimensional projection screens for multiple people is generated. [0003] Since the rear projection hard screen structure of the multi-channe...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a CAVE-based different-plane perspective correction and fusion system. By using a graphics processor to convert an image into an editable image, the point correction unit pulls the control in the editable image point, make the lines in the image coincide or be parallel to the image content, correct the image, the virtual coordinate unit generates the corresponding virtual space projector coordinates according to the image content and the direction of the projector, and the 3D image unit generates real-time coordinates according to the projector coordinates Generate stereoscopic images of the corresponding projection surface, and the number of processing computers and graphics processors is the same as the number of projection surfaces. Multiple processing computers are connected by synchronous cards, and the system can send commands within the minimum response time, so that the system after perspective correction The graphics will not be deformed and distorted, the vertical lines in the image can match the image content, and the investment is small, the operation is simple and easy to go online, and the practicability is strong
