Embodiment 1

[0064] This embodiment provides a projection geometry adjustment method, which can be applied to a projection fusion system of multiple projectors, which includes the following steps: superimposing the projection feature image on the fusion zone and / or side and / or corner of the projection screen of the projector, Geometrically adjust the projection screen of the projector according to the characteristic image.

[0065] In the process of geometric adjustment of the projection screen, the characteristic image superimposed and projected on the projection screen only occupies a small area on the projection screen, and only occupies a small area, edge, and corner of the fusion zone of the projection screen, which is different from the existing Compared with the method of switching the projected picture to a grid picture or superimposing network lines on the projected picture, the impact on the perception of the projected picture can be reduced. Even in conferences, exhibitions and ...

Embodiment approach

[0077] According to step S1, the projected characteristic images are respectively superimposed on the positions corresponding to the fusion zone of the projection picture A and the projection picture B. In one embodiment, the characteristic images superimposed and projected on the fusion zone of the projection picture A are triangular in shape and filled inside For the image of a hollow circle, the characteristic image superimposed and projected on the fusion zone of the projection screen B is an image in the shape of a solid circle. At the same time, superimpose and project characteristic images on the upper left corner of the projection screen A and the upper right corner of the projection screen B respectively, and the superimposed and projected characteristic images are L-shaped images with filled oblique textures inside. The projection screen A and the projection screen B after superimposing the projection feature image are as follows: Figure 3A shown.

Embodiment 2

[0106] Based on the same inventive concept as in Embodiment 1, such as Figure 9 As shown, this embodiment provides a projection geometry adjustment system, which can be applied to a projection fusion system of multiple projectors, which includes a characteristic image projection module 510 and a projection screen correction module 520; the characteristic image projection module 510 is used for projection The projected characteristic image is superimposed on the fusion zone and / or the side and / or corner of the projected image of the projector; the projected image correction module 520 is configured to geometrically adjust the projected image of the projector according to the characteristic image.

[0107] In the process of geometric adjustment of the projected picture, the feature image projected by the characteristic image projection module 510 superimposed on the projected picture only occupies a small area on the projected picture, and only occupies a certain small area, sid...

Abstract

The invention relates to a projection geometric adjustment method, system and device and a storage medium, and the method comprises the steps: projecting a plurality of feature images on a fusion bandand / or an edge and / or an angle of a projection image of a projector in an overlapping manner, and carrying out the geometric adjustment of the projection image of the projector according to the feature images. The geometric adjustment operation of the projection picture can be simpler, more convenient and faster, the geometric adjustment of the projection picture can be realized only by superposing the projection feature image in the small-range area of the projection picture, the influence on the impression of the projection picture is reduced, and the geometric adjustment of the projectionpicture can also be carried out in normal scenes such as conferences and exhibitions.

Description

technical field [0001] The present invention relates to the technical field of projection, and more specifically, to a projection geometry adjustment method, system, device and storage medium. Background technique [0002] The projection edge fusion technology is to project a video or image from more than two projectors 200, and smoothly transition the overlapping areas of the projection images, finally presenting a larger projection image. like figure 1 Shown is a projection fusion system taking two projectors 200 as an example. The image fusion processor 300 acquires initial video image data from a video source 400 and performs fusion processing on the video image data to form two video image data respectively. Projected onto the projection carrier 100 by two projectors 200, the projection areas of the two projectors 200 are the projection screen A and the projection screen B respectively, the overlapping area of ​​the projection screens of the two projectors 200 is the f...
