Abstract
The invention relates to a method for manufacturing and reading a screen bar code and a two-dimensional code. The method comprises the following steps: coding the image information of the bar code and the two-dimensional code by a bar code and a two-dimensional code generator to form electric signals which can be recognized by a screen; forming the screen bar code and the two-dimensional code by the light and shield change of the electric signals on the screen; clearly reflecting the screen bar code and the two-dimensional code on the surface of the screen by matching with a light source system; optically collecting the clear screen bar code and the two-dimensional code by using a bar code and two-dimensional recognizer; and forming readable machine information by analog-to-digital conversion and decoding according to different code systems. Compared with the prior art, the invention has the advantages that the consumption of natural resources, such as paper, and the production cost are reduced, the application ranges of the bar code and the two-dimensional code are expanded to a great extend, the bar code and the two-dimensional code are practically applied to the screens along with the popularization of mobile equipment, such as mobile phones, and the like, and the information replacement speed is greatly improved.
Description
Technical field
The present invention relates to bar code and two-dimension code recognition technology, the making and the read method of particularly a kind of screen bar code and two-dimension code.
Background technology
Tradition bar code and two-dimension code label in use can't be realized the change of data content.Simultaneously, bar code and two-dimension code label in actual use, the speed of information transmission is more slowly.When running into information-change, just need end user's force-summing device to make label again, change these information.Allow the raising of efficient and the scope of application be subjected to limitation of the technology like this.
Summary of the invention
Purpose of the present invention is exactly making and the read method that fireballing screen bar code of a kind of change dump and two-dimension code are provided for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: the making and the read method of a kind of screen bar code and two-dimension code is characterized in that this method may further comprise the steps:
(1) by bar code and two-dimension code maker the image information of bar code and two-dimension code is encoded, make it to become the discernible electric signal of screen;
(2) on screen, present light and shade by these electric signal and change, form screen bar code and two-dimension code;
(3) in screen surface, cooperate light-source system, screen bar code and two-dimension code are reflected clearly;
(4) screen bar code and two-dimension code carry out optically detecting clearly to these to use bar code and two dimension code reading utensil;
(5) by analog to digital conversion, decode, form the information that machine readable is got according to different code systems.
Described bar code and two-dimension code maker are bar code and the two-dimension code maker in the mapping softwares commonly used such as CorlDraw.
Described screen comprises ASV, TFT, OLED, TFD, UFB, STN or CSTN.
Compared with prior art, the present invention has the following advantages:
(1) consumption and the production cost of natural resourcess such as paper have been reduced;
(2) simultaneously, expanded the scope that bar code and two-dimension code are used to a great extent, along with the mobile device universalness of mobile phone particularly, bar code and two-dimension code are also along with screen implements to application;
(3) speed of change dump improves greatly.

Fig. 2 is the making of a kind of screen bar code of the present invention and two-dimension code and the bar code synoptic diagram of read method.
Embodiment
As shown in Figure 1, the type of screen is abundanter in the making of a kind of screen bar code of the present invention and the read method, ASV, TFT, OLED, TFD, UFB, STN, CSTN etc., from black and white to colorful screen.The advantage of bar code is that it is by bar and empty the composition.Therefore, color there is not too much requirement.Only need light and shade can form the element of bar/sky.Therefore presenting bar code on screen has technical conditions.
Encode by the image information that the bar code generator will bar code, make it to become the discernible electric signal of screen, on screen, present light and shade and change.Make naked eyes promptly can observe bar code image clearly.
Because different screen brightness, 400cd/m2 normally, the difference of characteristics such as material index of refraction.Need under certain light source, bar code can be reflected clearly.The bar code reading facility can be decoded by the image information of picked-up, reach required bar code information content.
We select DELL INSPIRON 710m type notebook computer for use, and screen is a TFT high brightness widescreen display.Bar code generator in the mapping softwares commonly used such as use CorlDraw.Generate various bar code graphics, and stick on the operation pages, and page adjustment is amplified to 200, for guaranteeing reading effect, the length of bar code graphics is not above 9 centimetres, and can be visually noticeable fully, the white space more than 1 centimetre is left on the bar code both sides, and bar code graphics is arbitrarily inartificial to stretch.
Use IT4206 type bar-code reader, the bar code (as shown in Figure 2) of aiming on the notebook computer screen scans, in 10～15 cm range, the angle between bar-code reader and the screen can successfully read bar code to bar-code reader between 60～90 degree to the distance of screen.Here no matter mainly be to select the image-type bar-code reader, be linear mode or area image mode equipment, all can realize above-mentioned functions.
Claims (3)
1. the making and the read method of screen bar code and two-dimension code is characterized in that this method may further comprise the steps:
