Embodiment 1

[0064] This embodiment provides a projection geometry adjustment method, which can be applied to a projection fusion system of multiple projectors. The method includes the following steps: superimposing projection feature images on fusion zones and / or edges and / or corners of the projection images of the projectors, The projected image of the projector is geometrically adjusted according to the characteristic image.

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

Embodiment approach

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

[0078] Under the condi...

Embodiment 2

[0106] Based on the same inventive concept as 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 image correction module 520; the characteristic image projection module 510 is used for The projected characteristic image is superimposed on the fusion zone and / or the edge and / or the corner of the projection image of the projector; the projection image correction module 520 is used for geometrically adjusting the projected image of the projector according to the characteristic image.

[0107] In the process of geometric adjustment of the projection image, the characteristic image superimposed on the projection image by the feature image projection module 510 only occupies a small area on the projection image, and only occupies a small area, edge, and corner of the fusion zone...

Abstract

The present invention relates to a projection geometry adjustment method, system, device and storage medium, wherein the method comprises: superimposing and projecting several characteristic images on the fusion zone and / or sides and / or corners of the projected picture of the projector, and according to the characteristic images Geometry adjustment is performed on the projected picture of the projector. The present invention can make the geometric adjustment operation of the projection picture simpler and faster, and only need to superimpose the projection characteristic image in a small area of ​​the projection picture, the geometric adjustment of the projection picture can be realized, and the impact on the look and feel of the projection picture can be reduced. The geometric adjustment of the projected image can also be performed in normal scenes such as exhibitions.

Description

technical field [0001] The present invention relates to the technical field of projection, and more particularly, to a method, system, device and storage medium for adjusting projection geometry. Background technique [0002] The projection edge fusion technology is to project a video or image by two or more projectors 200 , and smoothly transition the overlapping area of ​​the projection images to finally present 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 obtains the initial video image data from the video source 400 and performs fusion processing on the video image data to form two video image data respectively. Projected by two projectors 200 onto the projection carrier 100, 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 images of the two projectors 200 is t...
