Embodiment Construction

[0016] Such as figure 1 , 2 As shown, the multi-touch interactive splicing method of the present invention includes the following steps:

[0017] 1) Build a large splicing screen

[0018] Splice a large splicing screen that forms total internal reflection according to the splicing sequence.

[0019] 2) Split-screen debugging and installation of the projector

[0020] There is a projector behind each splicing unit, and the picture covers the whole splicing unit, and the pictures of two adjacent splicing units overlap by more than 10 pixels.

[0021] 3) Split-screen debugging and installing infrared sensors

[0022] Each splicing unit corresponds to a sensor, the edge of the image of the sensor is the edge of the splicing unit, and the images of two adjacent splicing units overlap by more than 10 pixels.

[0023] 4) Projection fusion software for multi-projection fusion

[0024] Through the projection fusion software, the images of multiple projectors are fused to form a l...

Abstract

The invention provides a multi-point touch interaction splicing method for realizing ultra-large size and ultra-high resolution display. The method comprises the following steps: (1) constructing a large-scale spliced touch screen; (2) fusing multi-projection images, wherein each splicing unit corresponds to a projector, and the images of a plurality of projectors are fused into a high-resolution large image through projection fusing software; (3) splicing a plurality of sensor images, wherein an infrared sensor is placed behind each splicing unit for capturing reflected light, the images of the sensors are spliced into an ultra-wide viewing field image by adopting image tracing software, and a large splicing screen is captured; (4) tracing contacts; (5) touching to response; (6) calibrating split screens. According to the method, the ultra-large size and ultrahigh resolution display is realized through screen splicing and multi-image fusion and splicing, so as to meet the requirements of people on the visible size and display resolution of a displayed image.

Description

technical field [0001] The invention relates to a touch display method, in particular to a multi-touch interactive splicing method. Background technique [0002] Multi-touch refers to an operation mode that allows computer users to control the computer through multiple fingers or contacts at the same time, and multi-touch devices are touchable display or screen devices (such as computer monitors, desktops, walls), It can also be composed of a touchpad, and then the point where the simultaneous touch behavior occurs is identified and processed by software. Each optical-based multi-touch technology includes an optical sensor (usually a camera or video camera), an infrared light source, and a screen displayed by a projector or display panel. [0003] With the development of science and technology and the rapid expansion of the amount of information, people have higher and higher requirements for the visual size and display resolution of the display screen. But currently, ther...
