The operation principle of this detailed description of the invention: after pressing the control button 5 starting detection, detector is started working,
Color collector 4 carries out the data signal acquisition of color, and the rgb value of the color collected is stored in the depositor carried
In, STC89LE52 single-chip microcomputer reads the rgb value of corresponding depositor in TCS3414 color collector 4, and to the rgb value read
Process, including: rgb value being converted into XYZ color space and is worth accordingly, reconvert is to Lab value；Hue angle calculation h value；Will
This hue angle value substitutes in Capability Maturity Model and calculates final Maturity grade；Finally Maturity grade is shown
In LCD12864 LCDs 2.
Owing to STC89LE52 single-chip microcomputer has 36 I/O interfaces, enough meet TCS3414 4 I/O interfaces,
12 I/O interfaces of LCD12864 and the interface requirements of an I/O interface of button.The main calculating of the design is, by RGB
Color value to the conversion of XYZ tristimulus values, then and the conversion of Lab value, and then carry out the calculating of hue angle h, the most always pass through tone
Angle calculates the Maturity grade of Fructus Musae, and relate to is all elementary operation, therefore the computing capability of STC89LE52 single-chip microcomputer also foot
Enough.From the above mentioned, master controller STC89LE52 monolithic function meets hsrdware requirements.
In color collector 4 TCS3414 color sensing chip can colourity under accurately measure difference light intensity, and with
16 bit resolutions export, and this device has the optical filter of collection 8*2 array, analog-digital converter and control function and the whole body
CMOS integrated circuit, in 16 optical filters, have 4 Red lightscreening plates, 4 green color filters, 4 blue color filters and
4 all-pass optical filters.
From three primary colors principle of induction, if it is known that constitute the trichromatic value of shades of colour, just it is able to know that institute
The color of test object, for TCS3414, when a selected color filter, it only allows certain the most former
Color passes through, and stops other primary colors to pass through.Such as: when selecting Red lightscreening plate, in incident illumination, only redness can be passed through,
Blue and green is all prevented from, and so can be obtained by the light intensity of red light；In like manner, other optical filter is selected, so that it may with
Obtain the light intensity of respective color light, by these three RGB color value, just can analyze and reflex on TCS3414 sensor
The color of light.
During Measuring Object surface color rgb value, in the case of other conditions are identical, light source exposure rate is to survey
Value has a great impact, and will realize the repetition measurement of same color of object surface, and light source irradiates condition needs stable and consistent, by
It is continually changing in lamp, therefore lamp can not be selected therefore, select 4 white led lamps source 6-4 as illumination light
Source, is separated with extraneous lamp by black shell 6-1, in order to avoid the impact that external light source is on measurement result.
Object tristimulus values (tristimulus values) is that body surface causes human body retina to certain color sense
The expression of amount of the stimulations degree of the three kinds of primary colors felt, in trichromatic system, with X(red primaries quantity of stimulus), the stimulation of Y(green primary color
Amount) and Z(blue primary quantity of stimulus) expression, the calculating of tristimulus values be the spectral characteristic according to object, CIE standard illuminants and
Standard observer's function calculates.
Rgb value to be realized represents to the accurate conversion of XYZ value, the XYZ value i.e. realizing changing out with measuring the rgb value obtained
Same color (no color differnece), needs the color sensor under LED illumination light source in design is carried out characterization, i.e. finds a square
Battle array model, uses the method for Polynomial modeling that color sensor is carried out characterization, is formulated as: H=MP in the design,
Wherein P is input matrix, and M is the transition matrix (m is multinomial item number) of 3*m, and H is output matrix.When item number is 3, formula
Can be expressed as follows:
,i=1,2…240
Specific practice is made by GretagMacbeth 240 ColorCheck colour atla, and the method solved by naturalization is asked
Go out matrix M.
First calculating the XYZ value of each color lump in 240 colour atlas, computing formula is as follows:
, i=1,2 ... 240
WhereinFor the relative spectral power distributions (available spectrum radiancy measurement measure) of light source,It is 240
The spectral reflectivity (available spectrophotometer measurement obtains) of each color lump in colour atla,、、For spectral color three
Stimulus value, is the standard observer of CIE1931XYZ system during 2 ° of visual fields, is that the standard of CIE1964XYZ system is seen during 10 ° of visual fields
The person of examining.The design selects 2 ° of visual fields.K value in above formula to be obtained, then to utilize following formula to carry out inverse according to the Y=100 of light source
Again the XYZ value of each color lump in calculated 240 colour atlas is converted into Lab value, it is simple to calculate aberration, conversion public affairs
Formula is as follows:
i=1,2…240
Wherein
i=1,2…240
Each color lump in obtaining 240 colour atlasAfter value, (this is trueValue, is designated as), can
With one transition matrix M of random initializtion, in the design, multinomial item number selects 20, i.e. m=20, therefore M is 3*20 matrix.Defeated
Enter a matrix P and be also 20, specific as follows:
[1 R G B RR GG BB RG RB GB RRR GGG BBB RRG RRB GGR GGB BBR BBG RGB],
Input matrix P is the transposition of above row vector.
Just the predictive value of each color lump XYZ in 240 colour atlas can be obtained, further according to calculating Lab above after initializing matrix M
The formula of value calculates the predictive value of each color lump Lab value in 240 colour atlas, is designated as.Further according to following colour difference formula
Calculate the aberration of predictive value and actual value,
, i=1,2…240
Application naturalization method for solving the value of coefficient matrix M is optimized, when reaching aberration minimum required for be
Number conversion matrix.
Just the RGB color value arbitrarily detected can be changed after finding coefficient matrix M, and finally give color pair
The Lab value answered, by hue angle calculation h, then is brought into Capability Maturity Model formula and just can obtain corresponding Fructus Musae Maturity etc.
Level.
After using said structure, this detailed description of the invention has the beneficial effect that the one described in this detailed description of the invention is portable
Formula Fructus Musae Maturity detector, carries out the detection of Fructus Musae Maturity by the change of color in Fructus Musae maturation process, uses color
Harvester realizes the accurate measurement of Fructus Musae color, it is possible to decrease the cost of manufacture of Fructus Musae Maturity detector, reach light can be carry-on
The effect carried, and there is the advantages such as simple in construction, volume is little, cost of manufacture is low.
The above, is only in order to the technical solution of the utility model to be described and unrestricted, those of ordinary skill in the art couple
Other amendment or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should contain in the middle of right of the present utility model.
