Although it has the advantages of simple operation, strong expandability, and high reliability; and it can display several images at the same time; but in the fields of public security, transportation, production, etc., it is often desired to zoom in, zoom out, and move a specific image displayed in real time. operation, while the existing splicing large-screen splicing device can only rely on the mouse and keyboard to realize the above operations; and when the screen area is large, it is impossible to realize the operation while explaining, and the audience cannot actively choose the picture to watch, but can only watch it passively. Not conducive to meeting interaction

Embodiment Construction

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, the specific implementation steps of the method of controlling splicing a large screen by identifying the track of the light spot of the invention are as follows:

[0028] 1) Firstly, the user of the laser pointer moves the laser pointer to form the moving track of the spot on the splicing large screen; It has the characteristics of high brightness and no divergence, so it will reflect obvious light spots on the large screen. In order to avoid color interference on the large screen, the laser color is preferably green.

[0029] 2) Collect the moving track of the light spot on the large screen through the image acquisition device, and send the collected moving track of the light spot to the...

Abstract

The invention discloses a method and a system for controlling a spliced large screen by identifying light spot tracks. The method comprises the specific steps of moving a laser pen to form light spot moving tracks on the spliced large screen; gathering the spot moving tracks by an image collecting device; identifying the spot moving tracks by an image identifying system; to generating a control signal by a control system so as to realize a process of controlling the display contents of the spliced large screen, wherein the system for implementing the method is formed by the laser pen, the image collecting device, the image identifying system and the control system. The method and the system provided by the invention have the characteristics of being simple in structure, high in identifying precision, convenient to operate and the like.

Description

technical field [0001] The invention relates to the control field of splicing large screens, in particular to a method and a system for controlling splicing large screens by identifying light spot trajectories. Background technique [0002] Existing splicing large screens all need to use a large screen splicer to realize the control of the large screen. Although it has the advantages of simple operation, strong expandability, and high reliability; and it can display several images at the same time; but in the fields of public security, transportation, production, etc., it is often desired to zoom in, zoom out, and move a specific image displayed in real time. operation, while the existing splicing large-screen splicing device can only rely on the mouse and keyboard to realize the above operations; and when the screen area is large, it is impossible to realize the operation while explaining, and the audience cannot actively choose the picture to watch, but can only watch it p...
