[0020] like Figure 1 As shown, it is a flow chart of a detection method for jadeite raw stone provided by one embodiment of the present invention.

[0021] A method for detecting jadeite raw stone comprises at least the following steps:

[0022] S101, obtaining a target fluorescence image corresponding to a jadeite rough stone sample; wherein the target fluorescence image is used to indicate an image corresponding to an abnormal position of the jadeite rough stone sample determined when ultraviolet fluorescence detection is performed on the jadeite rough stone sample;

[0023] S102, determining that a first feature exists in the target fluorescent image, and obtaining a first position of the first feature on the jadeite rough stone sample; wherein the first feature is used to indicate a feature related to external processing on the jadeite rough stone sample;

[0024] S103, based on the first position, performing infrared spectrum acquisition to generate an infrared spectrum image;

[0025] S104, if the infrared spectrum image indicates the presence of an absorption peak associated with artificial materials, determining that the filling state of the jadeite rough stone sample is an artificially processed state;

[0026] Under normal circumstances, jadeite raw stones do not have fluorescence, but if there is dust, grease, fiber, small hair particles, and organic matter used for artificial counterfeiting on the jadeite raw stones, they will leave fluorescence. Non-processing factors include: dust, grease, fiber, small hair particles, etc.; external processing factors include: organic matter used for artificial counterfeiting, etc.

[0027] In S101, ultraviolet fluorescence test is performed on all exposed positions of the jadeite rough stone sample. If the ultraviolet fluorescence test result indicates the presence of a fluorescent position, the fluorescent position is determined as an abnormal position of the jadeite rough stone, and a magnifying glass with a preset magnification is controlled to collect an image of the abnormal position of the jadeite rough stone, thereby obtaining a target fluorescence image corresponding to the jadeite rough stone sample. The fluorescence wavelength used in the ultraviolet fluorescence test is 365nm.

[0028] In S102, here, there is no limitation on the specific process of how to determine whether the first feature exists in the target fluorescence image. For example, it is possible to determine whether the first feature exists in the target fluorescence image based on the jadeite raw stone fluorescence image library; it is also possible to determine whether the first feature exists in the target fluorescence image by performing image recognition on the jadeite raw stone fluorescence image.

[0029] The first feature is the feature left on the jadeite raw stone due to external processing factors. In other words, the first feature is used to indicate the features related to external processing on the jadeite raw stone sample.

[0030] The position information of the first feature on the jadeite rough stone sample, that is, the first position, is obtained based on the target fluorescence image.

[0031] In S103, the micro-region at the first position is sampled, and infrared spectrum of the sample is collected using attenuated total reflection method to generate an infrared spectrum image; wherein the maximum diameter of the micro-region is less than 1 mm.

[0032] In S104, here, it can be determined whether there is an absorption peak related to artificial materials in the infrared spectrum image based on the infrared spectrum library; it can also be determined whether there is an absorption peak related to artificial materials in the infrared spectrum image by performing image recognition on the infrared spectrum image.

[0033] The filling states of jadeite raw stone samples are divided into two types: artificially processed state and natural state.

[0034] This embodiment combines ultraviolet fluorescence and infrared spectroscopy, and can effectively identify the internal filling state of jadeite raw stone without damaging the jadeite raw stone, thereby improving the accuracy of jadeite raw stone identification; and solves the problem in the prior art that the jadeite raw stone is damaged due to the identification of the internal filling state of the jadeite raw stone.

[0035] Another embodiment of the present invention provides a method for detecting jadeite raw stone, which comprises at least the following steps:

[0036] S1, obtaining a target fluorescence image corresponding to a jadeite rough stone sample; wherein the target fluorescence image is used to indicate an image corresponding to an abnormal position of the jadeite rough stone sample determined when ultraviolet fluorescence detection is performed on the jadeite rough stone sample;

[0037] S2, for any jadeite raw stone fluorescence image in the jadeite raw stone fluorescence image library: calculate the similarity between the jadeite raw stone fluorescence image and the target fluorescence image; if there is at least one jadeite raw stone fluorescence image with a similarity greater than a preset threshold in the jadeite raw stone fluorescence image library, execute step S3; if there is no jadeite raw stone fluorescence image with a similarity greater than the preset threshold in the jadeite raw stone fluorescence image library, execute step S4;

[0038] S3, selecting the jadeite raw stone fluorescence image with the greatest similarity from the at least one jadeite raw stone fluorescence image as a reference fluorescence image; using the feature corresponding to the reference fluorescence image as the first feature corresponding to the target fluorescence image; and then executing step S5;

[0039] S4, determining that the first feature does not exist in the target fluorescent image; and performing an X-ray tomography scan on the jadeite rough stone sample to generate an X-ray tomography scan result; and then executing step S9;

[0040] S5, obtaining a first position of the first feature on the jadeite rough stone sample; wherein the first feature is used to indicate a feature on the jadeite rough stone sample related to external processing; and based on the first position, performing infrared spectrum acquisition to generate an infrared spectrum image;

[0041] S6, obtaining characteristic peaks of the infrared spectrum image; for any spectrum peak in the infrared spectrum library: calculating the similarity between the spectrum peak and the characteristic peak; if there is at least one spectrum peak whose similarity is greater than a preset threshold, executing step S7; if there is no spectrum peak whose similarity is greater than the preset threshold, executing step S8;

[0042] S7, determining the at least one spectral peak as an absorption peak associated with an artificial material; and based on the absorption peak associated with the artificial material, determining that the filling state of the jadeite rough stone sample is an artificially processed state;

[0043] S8, determining that the infrared spectrum image characterization does not have an absorption peak related to artificial materials, and performing an X-ray tomography scan on the jadeite rough stone sample to generate an X-ray tomography scan result;

[0044] S9, determining the filling state of the jadeite raw stone sample based on the X-ray tomography result.

[0045] When neither infrared spectroscopy nor ultraviolet fluorescence detection detects the internal filling state of the jadeite rough stone sample, the jadeite rough stone sample is subjected to X-ray tomography scanning by X-ray tomography technology, and the filling state of the jadeite rough stone sample is determined based on the X-ray tomography scanning results.

[0046] Specifically, the jadeite rough stone sample is placed in the sample chamber of the scanning device, and the jadeite rough stone sample is subjected to X-ray tomography according to a preset step length to generate an X-ray tomography result. Here, a suitable scanning voltage and current are set according to the size of the jadeite rough stone sample, and the scanning voltage is 150kV-450kv; the scanning current is 1.5mA-3mA.

[0047] The present invention combines ultraviolet fluorescence technology, red light spectrum technology and X-ray tomography technology to scientifically judge the internal filling state of jadeite raw stone without damaging the jadeite raw stone, thereby improving the accuracy of identification of the internal filling state of jadeite raw stone.

[0048] In a preferred implementation of the present embodiment, the method further includes: selecting an X-section image containing a through closed line from the X-ray tomography results; performing noise reduction processing on the X-section image to generate a noise-reduced X-section image; counting the area corresponding to different color areas in the noise-reduced X-section image; and determining the impurity composition and the content of each impurity in the jadeite raw stone sample based on the different area and color.

[0049] Specifically, since the X-section image containing the through closed line is a section image with more comprehensive information, in order to conduct qualitative and quantitative analysis on the internal filling state of the jadeite raw stone, it is necessary to select the X-section image containing the through closed line from the X-ray tomography results. Then, the selected X-section image is subjected to noise reduction processing, and the image contrast is enhanced by using the tone mapping method, so as to effectively obtain more detailed information of the image.

[0050] When other impurity minerals (such as albite, quartz, etc.) exist in the jadeite rough stone; due to the obvious density difference between other impurity minerals and the jadeite rough stone (i.e. jadeite), the jadeite rough stone sample will show different tones such as black, white, gray, and purple after X-ray tomography. Therefore, different color areas in the X-ray section image are obtained, and the areas of different color areas are counted, so that the distribution of impurity minerals in the jadeite rough stone samples can be qualitatively and quantitatively analyzed, further improving the accuracy of jadeite rough stone identification.

[0051] It should be noted that if the internal filling state of the jadeite raw stone is in a natural state, the X-section image will be gray; if the internal filling state of the jadeite raw stone is in an artificially processed state, the X-section image will show different color differences; different colors in the X-section image represent different minerals.

[0052] like Figure 2 As shown, it is a schematic diagram of the process of determining the filling state of a jadeite raw stone sample based on X-ray tomography results in one embodiment of the present invention.

[0053] Determining the filling state of the jadeite rough stone sample based on the X-ray tomography results includes at least the following steps:

[0054] S201, when the jadeite rough stone sample is a blinded material, if the X-ray tomography result indicates the presence of a through closed line, determining that the filling state of the jadeite rough stone sample is artificially processed and filled;

[0055] S202, when the jadeite raw stone sample is a window material, the grayscale image between different structural layers of the window opening part is obtained from the X-ray tomography results; if the difference between the average grayscale values ​​corresponding to the grayscale images of any two adjacent structural layers is greater than a preset threshold, it is determined that the filling state of the jadeite raw stone sample is a manually processed state.

[0056] Specifically, jadeite raw stones are divided into covered materials and window materials according to their appearance. When the jadeite raw stone samples are placed, the window part of the window material should be kept parallel to the sample bin table as much as possible, and the supporting material should be selected from lightweight materials such as plastic and foam.

[0057] When the jadeite rough stone sample is a covered material, multiple cross-sectional views of the jadeite rough stone sample are checked based on the X-ray tomography results. If a through closed line from top to bottom can be found based on the cross-sectional image corresponding to the three coordinate axis directions of the space, it can be judged that the filling state of the jadeite rough stone sample is an artificially processed state.

[0058] When the jadeite rough stone sample is a window material, the color and grayscale differences will appear due to the density differences of different structural layers (for example: glue layer, tin foil layer, dye layer, skin, internal jade meat, etc.) in the window opening part; for this reason, it is necessary to first calculate the average grayscale value corresponding to the grayscale image of any structural layer, and then calculate the difference between the average grayscale values ​​corresponding to any two adjacent structural layers; if all the differences are greater than the preset threshold, it is determined that the filling state of the jadeite rough stone sample is an artificially processed state.

[0059] It should be noted that when the jadeite rough stone is a window material, the internal filling state of the jadeite rough stone can also be judged based on whether there is a through closed line in the X-ray tomography results. This embodiment analyzes the X-ray tomography results of the window opening, thereby reducing the overall scanning of the jadeite rough stone sample and improving the timeliness of obtaining the filling state of the jadeite rough stone sample.

[0060] Therefore, this embodiment combines the inherent characteristics of different types of jadeite raw stones and uses X-ray tomography technology to intuitively present the internal filling state of jadeite raw stones. It can not only provide an intuitive and scientific diagnostic basis for the detection and identification of jadeite raw stones, but also can accurately identify the internal filling state of different types of jadeite raw stones based on X-ray tomography results, thereby improving the accuracy of jadeite raw stone identification.
