Abstract

The invention relates to a smart label using colors as information sources and belongs to the field of intelligent identification. The smart label uses the colors as the information sources and can contain information with higher capacity in a unit information source.

Description

Using color as the intelligent label of information source

Technical field

Intelligent label using color as information source involved in the present invention, specifically relate to a kind of intelligent label using color as information source using the color lump on assigned address as Information Resources of Standard Literature, the color lump of all the other positions gives different information by comparing from the color lump as Information Resources of Standard Literature on assigned address, greatly can improve the information capacity in unit information source.

Background technology

Color recognition carries out Color Picking by the RGB principle of three primary colours, the process of information conversion.Rgb color pattern is a kind of color standard of industry member, by obtaining color miscellaneous to the change of red (R), green (G), blue (B) three Color Channels and their superpositions each other, namely RGB is the color representing red, green, blue three passages, this standard almost include human eyesight can all colours of perception, be use one of the widest color system at present.

The RGB component that rgb color pattern use RGB model is each pixel in image distributes the intensity level in 0 ~ 255 scope.Such as: pure red R value is 255, G value be 0, B value is 0; R, G, B tri-value equal (except 0 and 255) of grey; R, G, B of white are 255; R, G, B of black are 0.RGB image only uses three kinds of colors, them just can be made according to the mixing of different ratios, screen reappears 16777216 kinds of colors.Under RGB pattern, often kind of RGB composition all can use the value from 0 (black) to 255 (whites).Such as, shiny red uses R value 246, G value 20 and B value 50.When all three kinds of signal component values are equal, produce gray shade.When the value of all the components is 255, result is pure white; When this value is 0, result is ater.

Existing label is as bar code, Quick Response Code, RFID label tag etc., the information capacity stored is relatively little compared with the present invention, intelligent label using color as information source involved in the present invention can expand the quantity of information in unit information source greatly, from theory, unit information source has the function of 16777216 systems.

Summary of the invention

Content of the present invention is to solve existing identification label as bar code, Quick Response Code, the problem that FRID label information capacity is less, improves the capacity in unit information source thus the jumbo identifying schemes of one reaching extension tag information capacity and propose.

Content of the present invention in order to achieve the above object, the scheme adopted increases by one piece of Information Resources of Standard Literature color lump before the color lump of label assignment information source, when fetch equipment reads the intelligent label using color as information source involved in the present invention, understand the original assignment of first automatic decision Information Resources of Standard Literature color lump and actual read value, and automatically calculate RGB three primary colours component error.And then carry out vector superposed according to three primary colours component error and assignment information source color lump actual value, draw actual assignment.

Because rgb color pattern uses RGB component that RGB model is each pixel in image to distribute intensity level in 0 ~ 255 scope.Such as: pure red R value is 255, G value be 0, B value is 0; R, G, B tri-value equal (except 0 and 255) of grey; R, G, B of white are 255; R, G, B of black are 0.RGB image only uses three kinds of colors, them just can be made according to the mixing of different ratios, screen reappears 16777216 kinds of colors.Under RGB pattern, often kind of RGB composition all can use the value from 0 (black) to 255 (whites).Such as, shiny red uses R value 246, G value 20 and B value 50.When all three kinds of signal component values are equal, produce gray shade.When the value of all the components is 255, result is pure white; When this value is 0, result is ater.Like this, the intelligent label unit information source using color as information source can have 16777216 information contents, has greatly expanded the information content in existing label unit information source.

Claims

1. it is characterized in that comprising using color as the intelligent label of information source: unit information source is stated with color, different colors represents different information; The information capacity comprised in unit information source is large.

2. the intelligent label using color as information source according to claims 1, it is characterized in that the information in the intelligent label using color as information source is made up of different color lumps, using color as the intelligent label of information source using the color lump on assigned address as Information Resources of Standard Literature, the color lump of all the other positions is by comparing with the standard color block on assigned address, and the color lump of different colours gives different information.
