Abstract
The invention provides a multi-camera synchronous tracking method for realizing multi-camera synchronous tracking and seamless image splicing for a touch screen. The method comprises the following steps: (1) constructing an infrared screen full of total internal reflection; (2), constructing a camera module for shooting the infrared screen behind the infrared screen according to the size of the infrared screen; (3) splicing images of multiple cameras, and conducting seamless splicing on a series of common images or video images with overlapped boundaries, so as to obtain an ultra-wide viewing field image which can show the infrared screen integrally; (4) carrying out target tracking with tracking software. Data are captured according to one visual input stream; after data processing, tracking data such as target point coordinates, contact sizes and target point motion trails are output, so as to realize multi-camera synchronous tracking and seamless image splicing.
Description
Technical field
The present invention relates to a kind of touch-screen display packing, especially a kind of touch-screen polyphaser synchronous tracking method.
Background technology
Along with the development of computing machine and image processing techniques, the Image Mosaics technology for obtain super wide view field image even panorama sketch solution is provided.Therefore need to realize a plurality of camera synchronization tracer techniques, and stitching image, a series of normal image that superposition boundary arranged or video image are carried out seamless spliced, thereby obtain the image of super wide visual field.And at present, can't realize the polyphaser synchronous tracking.
Summary of the invention
The invention provides a kind of touch-screen polyphaser synchronous tracking method that realizes polyphaser synchronous tracking and image seamless splicing.
Realize that the touch-screen of the object of the invention with polyphaser synchronous tracking method, comprises the steps:
(1) build an infrared screen that is full of total internal reflection;
(2) build a camera module, according to the size of infrared screen, build a camera module and take infrared screen after infrared screen;
(3) polyphaser picture splicing, a series of normal image that superposition boundary arranged or video image are carried out seamless spliced, thereby obtain the image of super wide visual field, image can the complete infrared screen that photographs;
(4) Trancking Software target tracking, when destination object contact infrared screen the infrared screen total reflection destroyed, the infrared light of contact point is returned, picture charge pattern software can be followed the trail of impact point, the output trace data.
Described step (1) builds the infrared screen method, at first cuts a transparent acrylic of rectangle, then is covered with infrared light in the acrylic surrounding, forms total internal reflection in transparent acrylic, consists of an infrared screen.
The camera of described step (2) is arranged according to ranks, and between every two adjacent cameras, shooting picture repeats 10 above pixels.
Touch-screen of the present invention is as follows with the beneficial effect of polyphaser synchronous tracking method:
Touch-screen of the present invention comes capture-data with polyphaser synchronous tracking method according to a video input stream, after data are processed, the output trace data, as movement locus of coordinate of ground point and contact sizes and impact point etc., realize the polyphaser synchronous tracking, and realize the seamless spliced of image.
Description of drawings
Fig. 1 is the schematic diagram that touch-screen of the present invention is used polyphaser synchronous tracking method.
Embodiment
As shown in Figure 1, touch-screen of the present invention comprises the steps: with polyphaser synchronous tracking method
1) build an infrared screen that is full of total internal reflection

2) build a camera module
According to the size of infrared screen, build a camera module 3 and take infrared screen after infrared screen.Camera is arranged according to ranks, and between every two adjacent cameras, shooting picture repeats 10 above pixels.
3) polyphaser picture splicing
A series of normal image that superposition boundary arranged or video image are carried out seamless spliced, thereby obtain the image of super wide visual field, image can the complete infrared screen 2 that photographs.
4) Trancking Software target tracking
The infrared screen total reflection is destroyed when destination object 1 contact infrared screen, and the infrared light of contact point is returned, and picture charge pattern software can be followed the trail of impact point, and the output trace data is as the movement locus of coordinate of ground point and impact point size and impact point.
Embodiment recited above is described the preferred embodiment of the present invention; be not that scope of the present invention is limited; design under spiritual prerequisite not breaking away from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical solution of the present invention all should fall in the definite protection domain of claims of the present invention.
