Embodiment 1

[0053] See figure 1 as shown, figure 1 Shown is a splicing and displaying method of a presentation. This method is applied to the control machine that stores the presentation. After being processed by the control machine, it is sent to the node machine screen for display. The method includes:

[0054] Step S11, obtaining the resolution of the video wall, the video wall is formed by splicing the screens of multiple node machines according to the preset layout;

[0055] Step S12, determine the image shape in the presentation according to the resolution of the video wall to display across the node machine screen;

[0056] Step S13, calculating the display parameters of the image shapes in the presentation on the screens of the spanning node machines;

[0057] Step S14 , displaying the corresponding presentation on the screen of the spanned node machine according to the display parameters.

[0058] exist figure 1In the shown embodiment, the screens of the node machines are spl...

Embodiment 2

[0061] See figure 2 as shown, figure 2 Shown is a splicing and displaying method of a presentation. This method is applied to the control machine that stores the presentation. After being processed by the control machine, it is sent to the node machine screen for display. The method includes:

[0062] Step S21, obtaining the resolution of the video wall, the video wall is spliced ​​by a plurality of node machine screens according to the horizontal arrangement of the node machine screens;

[0063] Wherein, the resolution of the screen of each node machine is known, so the resolution of the spliced ​​video wall can be obtained through the resolution of the screen of each node machine. The screen of the node machine can be arranged in the manner of 2 rows and 2 columns, or in the manner of multiple rows and multiple columns, which is not specifically limited here.

[0064] Step S22, determine the image shape in the presentation according to the resolution of the video wall to...

Embodiment 3

[0073] See image 3 as shown, image 3 Shown is a splicing and displaying method of a presentation. This method is applied to the control machine that stores the presentation. After being processed by the control machine, it is sent to the node machine screen for display. The method includes:

[0074] Step S31, obtaining the resolution of the video wall, the video wall is composed of a plurality of node machine screens placed and spliced ​​according to the inclination of the node machine screens;

[0075] Wherein, the resolution of the screen of each node machine is known, so the resolution of the spliced ​​video wall can be obtained through the resolution of the screen of each node machine. Since the screen of the node machine is placed at an angle, there are many ways of splicing, which will be introduced later with specific examples.

[0076] Step S32, determine the image shape in the presentation according to the resolution of the video wall to display across the node ma...

Abstract

The invention discloses a powerpoint splicing display method which comprises the following steps that the resolution of a spliced video wall is acquired; the image shape in the powerpoint is determined and the screen of a spanned node computer is displayed according to the resolution of the spliced video wall; the display parameters of the image shape in the powerpoint in the screen of the spanned node computer are calculated; and the corresponding powerpoint is displayed in the screen of the spanned node computer according to the display parameters. The screen of the node computer is spliced into the spliced video wall, the contents of the powerpoint are divided according to the resolution of the spliced video wall and the resolution of the screens of all the node computers, and the divided powerpoint is distributed to the screens of other node computers. The screens of all the node computers synchronously display the divided contents of the powerpoint according to the display parameters, so that a presentation screen with the resolution higher than that of a single node computer is spliced; and in such a manner, the powerpoint splicing display method can display the powerpoint onto the spliced video wall with high resolution, so that the problems of distorted contents and unclear effects are solved.

Description

technical field [0001] The present invention relates to the technical field of image splicing and display, and more specifically, relates to a method for splicing and displaying presentations. Background technique [0002] Typically, a projector is used to display a presentation from a computer. Since the resolution of the computer is fixed, the projector simply physically enlarges the presentation in the computer, so the content of the presentation will be distorted and the display effect will be unclear after being enlarged by the projector. [0003] If a large-scale video wall is used to display the presentation, a single computer is usually used to display the presentation, and then displayed on the video wall through RGB signals. The disadvantage of this approach is also obvious, because it is purely physical amplification, which distorts the content of the presentation. This is because traditional image segmentation only performs physical segmentation according to th...
