Problems solved by technology

However, in the process of putting several projectors together for screen projection, since different projectors are projected on different positions on the screen, and there are stitching seams between adjacent projection splicing, the displayed image may be blurred. The feeling of fragmentation, and it may also cause problems such as overlapping screens, missing screens, and different visual effects displayed on different screens.

Embodiment 1

[0066] The present invention provides a grid data generation method for multiple projectors to perform projection splicing correction, such as figure 1 shown, including:

[0067] Step 1: Determine the displayed information of the target screen, and at the same time, determine the projection position of each projector based on the target screen based on the displayed information;

[0068] Step 2: Adjust the position of the projector according to the position difference information between the projection position and the preset position, and based on the preset display information, set each projector corresponding to the displayed information at the target The projected data on the screen is corrected;

[0069] Step 3: Generate grid data based on the corrected projected data.

[0070] Preferably, the displayed information includes: the size of the overall display interface on the target screen after projection splicing, the size of the individual display interface projected by...

Embodiment 2

[0077] On the basis of Embodiment 1, in step 1, determining the displayed information of the target screen includes:

[0078] Shooting the target object in real time, and determining the movement information of the target object during the real-time shooting process;

[0079] Constructing a display model based on the target object and the movement information of the target object;

[0080] The display model is transmitted to a corresponding projector for projection to obtain the displayed information, and then determine the displayed information of the target screen.

[0081] In this embodiment, for example, the target object can be composed of a billiard ball and a billiard table, and the movement information is, for example, the rolling track of the billiard ball on the billiard table. Build gets.

[0082] In this embodiment, the preset display information may be obtained based on a display model and is pre-set, and the displayed information is realized by a projector set ...

Embodiment 3

[0086] Based on Embodiment 1, in step 1, determining the projection position of each projector based on the target screen based on the displayed information includes:

[0087] determining a current display model of each projector based on the preset display information;

[0088] Acquiring the displayed information of the target screen, and judging whether the displayed information is completely displayed on the target screen based on the preset display information;

[0089] If it is incomplete, extract the incomplete information, and match the incomplete information with the current display model of each projector to obtain a matched first projector and an unmatched second projector;

[0090] Determine the displayed blur degree and displayed color degree of the current display model corresponding to the unmatched second projector, and determine the position to be adjusted factor of the second projector;

[0091] According to the displayed information, determine the sequential...

Abstract

The invention provides a grid data generation method for projection splicing correction of multiple projectors, and the method comprises the steps: determining the displayed information of a target screen, and determining the projection position of each projector based on the target screen based on the displayed information; adjusting the position of the projector according to the position difference information between the projection position and the preset position, and correcting the projected data of each projector corresponding to the displayed information on the target screen based on the preset display information; and generating grid data based on the corrected projected data. By determining the position difference information between the displayed information and the preset display information, the data can be corrected conveniently, then the grid data is generated, and the reliability of projection splicing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of large-screen projection, in particular to a method for generating grid data for multiple projectors to perform projection splicing and correction. Background technique [0002] Projection splicing is also called projection splicing, which refers to two or more projectors projecting and splicing a large picture at the same time, without using projection edge fusion, and directly making the pictures projected by each projector close together. However, in the process of putting several projectors together for screen projection, since different projectors are projected on different positions on the screen, and there are stitching seams between adjacent projection splicing, the displayed image may be blurred. Fragmentation, and it may also lead to problems such as overlapped screens, missing screens, and different visual effects displayed on different screens. [0003] Therefore, the present invention propose...
