Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1, Color Recognition System comprises white light source module 30, color acquisition module 20, single-chip microcomputer 10 and LCD display 40, wherein, white light source module 30 comprises white light source and connected seal channel (referring to Fig. 2), and the light of white light source shines on the testee after by the total reflection of sealing passage.White light source can adopt near pure white high light LED.Utilize seal channel that the distance of color samples can not become, the energy of the decay of the light of the testee that namely collects reflection is the same, can be compensated the processing stage of the data of back, so do not consider the decay of the light intensity that receives.Be understandable that Color Recognition System also is included as the power supply (not shown) of its various piece power supply.
Among the embodiment of the present utility model, single-chip microcomputer 10 adopts STC12C5406AD, in the present embodiment mainly be that timer, counter, the serial ports of having used this single-chip microcomputer is current, PWM control, I the function such as O data transmission.
Color acquisition module 20 comprises color sensor and collector lens (referring to Fig. 2), and before collector lens was installed in color sensor, the light of testee reflection was gathered by color sensor by this collector lens.Collector lens can so that most reflected light received by color sensor, distance between testee and the collector lens can be arranged shorter in addition, extraneous mixed and disorderly light almost can not arrive sensor, thereby can guarantee that color sensor exports accurately frequency.
Color sensor adopts TCS320 among the embodiment of the present utility model, and it is very high to light source requirements, and the same color is measured frequency sample not in different measured distances, different lighting environment.Optical sensor for TCS320, it is not identical to the susceptibility of these three kinds of Essential colour, cause the RGB output of TCS320 also unequal, so must utilize white balance to regulate and compensate, TCS320 is equated to the three primary colors in " white " that detects.
Color sensor is converted into digital signal with the light signal that gathers and sends to single-chip microcomputer 10 and carries out data and process, and namely carries out color identification, obtains HSI value and the rgb value of different colours pattern, and sends to LCD display 40 and carry out the numerical value demonstration.Wherein the HIS value comprises respectively the value of tone H (Hue), saturation degree S (Saturation) and intensity I (Intensity), and rgb value comprises the intensity level of red R (Red), green G (Green) and blue B (Blue).What LCD display 40 was selected among the utility model embodiment is 1602 character type LCD display, can show two row, and 16 characters of every row can show the value of three variablees in each color mode of the required demonstration of the utility model.Carry out data when processing at single-chip microcomputer 10 among the utility model embodiment, can carry out data according to pre-stored white balance gene processes, white balance gene can obtain in advance by the learning functionality of single-chip microcomputer 10 one group of frequency reference value that represents white light, and then calculating 3 adjustment parameters is the scale factor (being white balance gene) of primary colours; The study of single-chip microcomputer 10 is divided into 1 time and repeatedly.Study is once left parameter white balance gene (this parameter is storing always), when identifying later at every turn, just calls this factor and carries out blank level adjustment.Study repeatedly is when carrying out color identification, all to carry out first white balance at every turn, obtains white balance gene (this white balance gene is for temporary, only for this color identification), then carries out color identification by single-chip microcomputer.Repeatedly carrying out white balance is to put forward high-precision a kind of method.
Among the utility model embodiment, the dutycycle of TCS320 output is the pulse of 50% different frequency, so can record with the counter of single-chip microcomputer 10 umber of pulse that arrives the T0 mouth.There are two kinds of methods to weigh three kinds of component values of RGB.The first: gating red diode array, allow the T0 rolling counters forward, timer begins timing simultaneously, when the number of T0 counter reaches 255, extract the time in the timer, in like manner can record the time of blueness, green component, again by the white balance adjusting factor, then can obtain the rgb value of the corresponding color of surveying.Second method: gating red diode array, allow the timer be a set time surely, counter begins counting, when timer overflows, extract the numerical value in the counter, obtain with red count value, in like manner can obtain the value of blueness, green component, by white balance adjusting, then can obtain the RGB actual value of the respective color of surveying again.Through experiment test, the accidental error of second method is less than the first, thus adopt the second method counting, and through repeatedly sampling, the error that is averaging rear rgb value can be very little.
White balance adjusting is to adapt to various different occasions, Color Recognition System of the present utility model has the autonomous learning function, namely before distinct color, first surrounding environment is learnt, obtain one group of frequency reference value that represents white light, then calculating 3 adjustment parameters is the scale factor of primary colours.The three primary colours umber of pulse that single-chip microcomputer 10 among the utility model embodiment records color sensor multiply by its corresponding scale factor again, obtains corresponding R, G and B frequency values, by the reducible color that goes out object under test of three-color LED.With this standard as color discrimination, thus the reliability of raising system.
As to establish scale factor be K, and the red color component value that records during white balance is R0, and the red color component value of testee practical measurement is r, and then the true R component after the correction of testee is:
R=K*r=255*（r/R0）；
Blue component in like manner:
B=K*b=255*（b/B0）；
Green component in like manner:
G=K*g=255*（g/G0）。
