Description

A kind of colors automatic recognizing system

[technical field]

The utility model relates to logistics management, relates in particular to the color automatic identification technology in the logistics management.

[background technology]

Often need discern the goods of different classes of or model in the logistics management, most at present employing bar codes, numbering, color etc. are discerned.

The technology of employing bar code recognition is comparative maturity, but cost is higher.That adopts numbering identification can only lean on manual observation, and efficient is low, makes mistakes easily.That adopts color identification does not also have widespread use at present, all is to adopt artificial cognition yet, and efficient is low, make mistakes easily, and the people of colour blindness can't operate at all.

So, how color-coded on the goods discerned automatically, judge the classification or the model of goods by the identification of color, and cost is low, becomes the important topic of those skilled in the art's research.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of colors automatic recognizing system, can discern color-coded on the goods automatically, and to distinguish the classification or the model of goods, cost is low.

For achieving the above object, the utility model proposes a kind of colors automatic recognizing system, comprise adopting look device, RGB acquisition module, color identification module and exporting display module of connecting successively, the described look device output chrominance signal of adopting is given the RGB acquisition module, the RGB acquisition module is exported to the color identification module with the color numerical value that obtains, and the color identification module is exported to the output display module with the color that identifies and shown.

As preferably, the described look device of adopting comprises that camera bellows, camera assembly and look source gather the hole, and described camera assembly is arranged in the camera bellows, and the look source is gathered the hole and is arranged on the face of camera bellows.

As preferably, described camera assembly comprises camera, removable flat board, support and output line, and described camera is placed on the removable flat board, and stent support is below removable flat board, the output terminal of camera is connected with output line, and described output line transfers data to the RGB acquisition module.

The beneficial effects of the utility model: the utility model is sent to the content of camera picked-up in the computer by the USB transmission line, obtains rgb value by software module again, according to the corresponding relation of rgb value that is obtained and color, color is discerned automatically.Specific goods adopts specific color, like this, just can discern automatically cargo type or model easily in the logistics management field.The utility model realizes that cost is low, easy to operate.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Fig. 2 is a structural representation of adopting the look device in a kind of colors automatic recognizing system of the utility model.

[embodiment]

Fig. 1 is the structural representation of a kind of colors automatic recognizing system of the utility model.Comprise adopting look device 1, RGB acquisition module 2, color identification module 3 and exporting display module 4 of connecting successively, the described look device 1 output chrominance signal of adopting is given RGB acquisition module 2, RGB acquisition module 2 is exported to color identification module 3 with the color numerical value that obtains, and color identification module 3 is exported to output display module 4 with the color that identifies and shown.The described look device 1 of adopting comprises camera bellows 11, camera assembly 12 and collection hole 13, look source, and described camera assembly 12 is arranged in the camera bellows 11, and the look source is gathered hole 13 and is arranged on the face of camera bellows 11.Described camera assembly 12 comprises camera 121, removable dull and stereotyped 122, support 123 and output line 124, described camera 121 is placed on removable dull and stereotyped 122, support 123 be supported on removable dull and stereotyped 122 below, the output terminal of camera 121 is connected with output line 124, and described output line 124 transfers data to RGB acquisition module 2.

Fig. 2 is a structural representation of adopting the look device in a kind of colors automatic recognizing system of the utility model.Camera 121 obtains outside colouring information and sends in the computer by USB interface, adopts RGB acquisition module 2 to obtain the rgb value of current color information in real time, proposes a color system at this system, whole colour gamut is divided into 512 parts, and is numbered.According to experimental result these 512 color codes are assigned to ten kinds of common colors, reach ten kinds of common colors of color identification by color identification module 3 at last, again the color that identifies is shown to the user by output display module 4.

Camera 121 is clipped on removable dull and stereotyped 122, moving removable dull and stereotyped 122 makes cam lens gather about the 13 about 60mm of hole apart from the look source, the light source of system be the LED lamp that carries of camera in order to avoid the high light part of its reflection, cam lens is upwards raised about 20 °.Camera 121 is received on the computer by output line 124.Because rgb value is subject to the influence of extraneous light intensity,, adopt camera bellows 11 that imaging environment and external environment is isolated for reducing the influence that this error causes system.Adopt the some points on the uniform relatively zone of brightness to get RGB, weighted mean obtains final rgb value then.

Chromaticity coordinate figure rgb and tristimulus values RGB dual mode are arranged in the differentiation of color.Wherein $r=\frac{R}{R+G+B},$ $g=\frac{G}{R+G+B},$ $b=\frac{B}{R+G+B}.$ If use chromaticity coordinates value rgb to distinguish color, then because the absolute figure of rgb value is less, the scope of chromaticity coordinates value rgb is very little, and measured value has little fluctuation just to cause big error easily, easily makes software erroneous judgement occur; And the scope of tristimulus values RGB is bigger comparatively speaking, therefore as long as fluctuation is not very big less with regard to error.And chromaticity coordinates value rgb is not very sensitive to brightness; The color category that can describe is less, so as preferred, the utility model adopts tristimulus values RGB to come different colours is distinguished.

Draw by experiment, the measured value under different color blocks, the different operating condition and the variation tendency of ideal value are roughly the same, but a certain distance is numerically arranged.Therefore, based on the actual measured value in look source, divided the color gamut that is adapted to native system and look source:

The color coding rule list:

Native system will be assigned to ten kinds of common colors such as white, black, red, green, blue, yellow, pink, cyan, orange, gray to 512 color codes according to actual needs, discern this ten kinds of common colors by software.
