Be used for jewel is carried out the method for standardization classification and relevant device

The present invention relates to a kind of jewel hierarchy system.More particularly, the invention provides automatic classification of a kind of jewel and data management system, be used to assess the value of jewel, and jewel is carried out unique identification.

The monetary value of diamond, pearl and other precious jewel can have very big difference according to the aesthetic features of each jewel.This feature for example comprises that color, transparency, cutting, shape, brightness or the like are the important subjective factors of its value of decision.For example, the jewel of usually finding same size and weight is owing to the influence of these subjective factors is worth very different.Thereby unified measurement of these characteristics is the reliable first steps estimated of monetary value that obtain jewel.

Utilize various instruments to the jewel classification now, this instrument comprises simple eyeglass or magnifier, and the Image-forming instrument of many complexity.Image-forming instrument is generally used for estimating the objective and subjective quality of jewel, and these instruments comprise simple UV-lamp, microscope, color filter, calcite type dichroscope, refractometer, polarizer, spectroscope or the like.Image-forming instrument can make the operator by illumination or amplify and to carry out visual analysis, perhaps utilize electronic method measure jewel to incident light refraction and reflection characteristic.

But, Image-forming instrument and system can not produce the index of the objective subjective quality of reliable and reproducible jewel at present.The selection of Image-forming instrument, people's judgement and eyesight feel it is the conforming whole factors that influence the jewel assessment.Thereby this assessment is some subjective factors of energy measurement not in the past, for example, and brightness, gloss, luminance brightness and cut quality.

For example, according to tradition, the color grading of jewel can not be considered size, transparency, flaw, the fluorescence of jewel, lacks standard method when the preparation sample, and utilizes equal or unequal illumination.The some instruments and the method that are used for color grading depend on the instrument that is used for sample is carried out the visual comparison of color, and these instruments are subjectively distributed to a kind of color according to described comparison.Because the judgement of known person and eye vary with each individual, so this color grading system is insecure.Some complicated instruments mix colours by measuring from the light frequency branch of surface emitting or reflection, and other use the change of reference light estimated color spectrum, also have some then light frequency to be converted to three looks, and it is used to an object branch is mixed colours.Yet the existence of fluorescence can change the frequency of color in the diamond more than 50% and many other jewels.Therefore the amplitude of UV radiation in light source will influence color grading.Just as can be seen, these devices do not reach as yet for the jewel acceptable consistance of concluding the business.

This has just finished the step of taking the image that uses in the jewel classification.Should be noted that by as seen above-mentioned device 5 can be used to obtain other image.

Referring now to Figure 10 A-10C,, wherein show the example that obtains and organize the method for the image of taking by imaging device, more particularly, the mode of utilizing the incident light data in jewel classification and jewel identification is described.In beginning, in the step 200, the counter of processing parameter, constant and native processor 10 is initialised, and the light-emitting component of imaging device is calibrated so that guarantee consistance on minute light quantity.Produced one group of pixel data image by each jewel of this device analysis according to the present invention.The image of each analyzed jewel is stored in unique Study document folder in the storer of local station 8.File is organized into the file of being taken by device 5 to the pixel data image together together with text, and wherein text contains the net result relevant for entitlement, analysis, the information that appraisal report is relevant with other.Text can by by device 5 suitable user interface manually input information produce.

The data processor 21 at the analyzed station 14 of the view data in the file of local station 8 is analyzed.In a preferred embodiment, file or image and text data group are sent to analysis station 14 and are used for handling and collect at the analysis station database.File and content thereof are replicated in order to safety, and after this, the content of file is analyzed, so that according to being prepared appraisal report by the pixel image of the jewel of the analysis of being transmitted.

Referring now to Figure 10 A,, local station 8 produces unique file in the steps 202, is used to store the jewel evaluating data.The jewel of the method utilization shown in it is a diamond.Begin by determining the otch of a bit determining jewel on the jewel periphery from going on foot 204.The profile of diamond is a group of pixels for the low convex of the brighter background pixels gray-scale value of color.Be used to be identified in borderline pixel from bright change to darker pixel.Utilize the shape and the pixel gray-scale value identification corner point of known diamond.Like this, be in the analysis of example with the diamond, these points have been determined table top, edge and bottom surface (table, girdle, full-size culet).Every millimeter pixel value is known, and every cubic millimeter Carat alternatively is defined as .00173801 roughly.Like this, carry out the calculating of multiple jewel, determine the size of jewels by the processor 10 of local station 8 by coordinate according to the diamond of content of determining and acquisition.Processing goes on foot the turning is extracted in 206, the first otch analyses by contour images (A1) coordinate data.The size coordinate of jewel is stored in the file of file.Then, in the step 208, determine the jewel dimension scale by utilizing the coordinate points that obtains to calculate by the jewel size.In the step 210 and 212, counter repeats this processing so that obtain to be used to analyze the required image of jewel of refining otch, for nearly maximum 8 this images of the jewel of the refining otch of circle.Repeat this processing, all processed up to all contour images.

In the step 214, the marginal point of the maximum by determining the jewel periphery is proceeded the otch analysis, at step 216 storing coordinates, at step 218 edge calculation size and girths.

Referring now to Figure 10 B,, last otch analysis comprises the step 220 that is used for determining the table top coordinate.Because the mesa structure of circular gloss otch generally is octagon, so the utilization structure algorithm is tried to achieve corner point.For some refining otch and use cursor manually to cover the corner point of table top where necessary.Step 222 allows the operator manually to import these data by going on foot 224.The table top coordinate is stored in the file of the file of the store memory storage of local station 8.Coordinate data is further analyzed according to the process flow diagram in step 230 and 232, so that calculate the size at edge well known to those skilled in the art, the width of table top, the height of table top, height, booth angle, table top angle, edge thickness and the various ratios relevant with otch analysis and jewel evaluation of bottom surface.Classification analysis is assigned as an otch grade in hyperspace to the otch grade of jewel according to the degree of approach of jewel.

The color analysis of jewel is in steps 234 beginning, wherein by by color image (A2, A3, A6 in edge and the table top image represented pixel area ...) obtain the mean value of R, G, B (RGB), by the color of sampling, obtain more predictable accurate color readings than the zonule.Step 236 and 238 provides the selection of manual input R, G, B value.In the step 240, R, G, B image sets are stored in the file of jewel Study document folder.The R that is got, G, B picture number are determined in the step 242 and 244 by counter.

The refraction of the light that is caused by the diamond as jewel makes the color of jewel itself produce error and makes the RGB color readings produce error.In addition, luminous energy is refracted and becomes spatial component and increase standard error in the RGB mean value.The software of the data processor 21 of analysis station 14 compensates this error by remove individual values from the analysis of statistics.After this, calculate the mean value of RGB pixel intensity value in the step 246.

Referring now to Figure 10 C,, in the step 248, average RGB value is obtained by the color of gemstones image (A17) under the ultraviolet ray irradiation.In the step 250, the difference between the value when not having the average RGB value in when irradiation ultraviolet ray and the ultraviolet ray irradiation being arranged is used to determine the existence of fluorescence.Fluorescence reduces the value of diamond.Use statistical model to carry out this analysis.Equally, the RGB value that is obtained by color image is converted into C.I.E., L.A.B and L.U.V. coordinate.Before distributing color grade, carry out the flaw analysis in the step 252.Can manually carry out flaw identification, as go on foot shown in 254 and 256.

Use a kind of Processing Algorithm to carry out the flaw analysis.Internal flaw, impurity, pin mark etc. are given prominence in the combination of usage threshold value and optical filter.Measure the size and the position of these flaws.By described algorithm identified internal flaw and be retained in the file (A27).The grade of relatively distributing clarity of the total area of the jewel face of determining according to the size of flaw with according to the position; Near table top with more reduce the value of jewel than flaw at the flaw of table top inside away from the surface and the zone that keeps to the side.In the step 258, the flaw data are stored in the file of Study document folder.Flaw is identified and is labeled, and produces jewel image file (A28) in the step 262.At step 260 analysis images (A9), (A10), (A25) and (A26), so that determine The Luster of Gems, light and carry out the light analysis.Take this method so that obtain information as much as possible, so that determine whether this system analyzed same jewel.

In order to carry out the gloss analysis, use a kind of Processing Algorithm from the gloss image, to extract average RGB value.Calculate the L.A.B. and the L.U.V. trichromatic coordinate of C.I.E., standard, be used to regulate light intensity.Use the ratio of average gray value and standard value to calculate gloss.Measure the polishing degree by making image by the sum that first thresholding calculates the pixel with average gray value on threshold value then.Be used to measuring light brightness by these pixels divided by the merchant of the total gained of the pixel on gemstone surface.Described quantity is big more, and the throwing shading value is big more.By extracting the polishing degree that average RGB value is determined table top from table top image A 23.For the average RGB value of incident light adjustment.Polishing degree grade by more controlled RGB value and standard value distribution table top.In case flaw, gloss, light and the analysis of polishing degree are done, then carry out the database at retrieval analysis station 14, so that determine whether to exist the analytic record of this jewel that carries out before the representative, determine perhaps whether analyzed jewel is included in the record that is used for the jewel of losing that mates in the database.Use the grading search technology so that reduce retrieval time in the step 264 and 266.If there is more than one jewel to be identified, then compare, so that mate in good condition by data processor.In theory, after only finishing, just use classification or linear identification model to mix colours according to weight, flaw and the fluorescence branch of trichromatic coordinate, diamond in the step 268 in this step.For the diamond of new cutting, obviously do not need searching database.Analysis result is retained and prints the local station 8 that report sends to requirement analysis.

Remove and estimate outside the jewel, analysis station 14 also was complementary by device 5 characteristics that analyze and that be stored in the jewel in the database with former to the characteristic of analyzed jewel 7.In addition, database can be inquired about so that some characteristic and/or the Price Range of jewel 7 are registered, and as the current market price information of preserving in the database, and is used to estimate jewel.Analysis station 14 can be used for classification, coupling, identification, classification and evaluation, and gives the local terminal report by multiple communicate.
