Projection method and system based on three-fold screen field and three-fold screen field

Abstract

The invention discloses a projection method and system based on a three-fold screen field and the three-fold screen field, and relates to the technical field of image processing. The method comprisesthe steps: obtaining position reference information corresponding to a watching position and a virtual scene corresponding to the three-fold screen field of a current projection size; calculating azimuth view angles of the viewing position in three azimuths in combination with the position reference information; generating a virtual picture corresponding to each azimuth view angle by the virtual scene according to each azimuth view angle; and fusing the virtual pictures of the three azimuth view angles into a scene picture for watching the virtual scene at the watching position, and projectingthe scene picture to the three-fold screen field. According to the three-fold screen field, the size of the projection area can be changed according to actual requirements, and the adaptability is high; and the projection effect is changed along with the change of the viewing position, so that a viewer can truly view a three-dimensional scene image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a projection method and system based on a three-fold screen site, and a three-fold screen site. Background technique [0002] At present, the use of multi-screen fusion is mostly limited to planar fusion, that is, multiple screens are generally connected and fused for imaging. Its three-dimensional space multi-screen fusion imaging is rarely used, and 3D software is used for manual stitching in the fusion imaging process, which is often used in commercial performances and other occasions; such as furniture display, floor layout display, etc. [0003] During the display, the three-dimensional space in reality adopts the same six-sided space structure as the room, which is a fixed space size, and the size cannot be changed to meet the needs of different users who want to experience imaging and viewing in different space sizes; and sometimes the projection does not need Al...
