Cross multi-directional cylindrical screen full-coverage projection method, system and projector

Abstract

The invention discloses a cross multi-directional cylindrical screen full-coverage projection method, a cross multi-directional cylindrical screen full-coverage projection system and a projector. Theprojection method comprises the steps of dividing a visual platform to be projected into cylindrical screen projection planes, arranging each projector to be arranged according to the maximum light path distance information projected from each projector to be arranged to each cylindrical screen projection plane to obtain a first projection coverage, and adjusting the first projection coverage based on a preset projection surface according to the setting parameters of each corresponding projector to be arranged to obtain a second projection coverage; and calculating geometric parameters of eachprojector to be arranged and the second projection coverage to obtain a spatial position and a rotating angle range of the projector to be arranged. The method and the system realize integrated optimization of projector arrangement, solve the problem of small pictures caused by relatively short distances between the projectors and the cylindrical screen projection planes in small and micro spacesby cross arrangement, and use common focus projectors.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a projection method, system and projector with cross-arranged multi-directional ring screens for full coverage. Background technique [0002] The CAVE projection system is a large-scale VR system (such as VR-Platform CAVE), which has a high degree of immersion, good interactive means, can integrate vision, touch, sound, etc., and can track the movement of the head in 6 degrees of freedom . The principle of the CAVE immersive virtual reality display system is relatively complicated. It is based on computer graphics and integrates high-resolution stereoscopic projection display technology, multi-channel visual synchronization technology, 3D computer graphics technology, audio technology, and sensor technology. fused together to produce a fully immersive virtual environment surrounded by three-dimensional projection images for multiple people. Currently, real-time...

Problems solved by technology

[0004] The purpose of the present invention is to provide a projection method, system and projector with cross-arranged multi-directional ring screen full coverage, which not only realizes the integrated optimization of optical-mechanical layout, but also breaks through the limitations of optical components of single-optical projectors, and achieves The method solves the problem of insufficient frame size caused by the relatively close distance between the optical machine and the projection plane of the ring screen in small and micro spaces; at the same time, it is not necessary to use a special short-focus optical machine to meet the size of the projection surface, but a general-purpose ordinary focal length optical machine can be used Realize the requirements of the format covering small and micro spaces
