Fusion and interaction system for extra-large-breadth display contact

Abstract

The invention discloses a fusion and interaction system for an extra-large-breadth display contact, which comprises a projector, a plurality of display screens, cameras and an interactive laser pen, wherein the projector and the display screens are connected with a projection host; the cameras and the interactive laser pen are connected with an interaction host; the display screens are spliced to form an extra-large-breadth display screen; the projector is used for projecting images onto the extra-large-breadth display screen; infrared laser emitted from the interactive laser pen is projected onto the extra-large-breadth display screen to form interactive contacts; the back of each display screen is provided with more than two cameras; the cameras simultaneously track and collect the image data comprising a laser point coordinate on a single display screen corresponding to the cameras; and the data is transmitted to the interaction host connected with the cameras; the interaction host processes the data so as to obtain an image which can reflect the laser point movement state; and the image data is fed back to the projection host and is projected on the extra-large-breadth display screen by the projector connected with the projection host.

Description

technical field [0001] The invention mainly relates to the super-large screen display touch fusion interaction technology. Background technique [0002] With the development of battlefield surveillance and reconnaissance technology, a large amount of intelligence information can be obtained in military command applications to form an overall battlefield situation. In order to effectively organize and use these data, it is generally necessary to use a large-format, high-resolution display system to realize the comprehensive display of various battlefield data, which improves the commander's perception of the whole process of the war. Ultra-large format display systems mainly refer to display devices with a display area greater than 200 inches and a resolution greater than 2056×2056dpi. Due to their large size and high resolution, such devices are generally assembled by splicing multiple small-sized display units. At present, such devices generally do not support direct inter...

AI Technical Summary

Problems solved by technology

However, there are still two deficiencies in the above system, which are as follows: ①The number of cameras used for laser interaction point tracking is generally installed in the middle of the display unit, and the interaction accuracy at edges and corners is low; ②Influenced by Limited to the image acquisition resolution of the camera, the interaction accuracy is low in the application of large-format and high-resolution display systems
