Description

Technical Field

[0001] This invention belongs to the field of jewelry and jade technology, and in particular relates to a method for detecting internal defects in jadeite rough based on X-ray detection. Background Technology

[0002] The trading of jadeite rough has a history of thousands of years. It is a unique and highly popular way of trading high-end jadeite rough in the border area between Myanmar and Yunnan. Its strong trading nature and high excitement attract jade merchants from all sides to spend a fortune, making it a long-standing and thriving industry. Since the beginning of jadeite rough trading, people have been looking for commonalities in various jadeite rough trading activities, trying to find their patterns to guide the practice of jadeite rough trading. However, jadeite rough undergoes erosion, transportation, deposition, and weathering during its later transportation, forming a weathered layer, or weathered rind. The thickness of the weathered rind varies depending on the transportation process and environment the jadeite rough has experienced. Therefore, it is impossible to directly judge the internal quality of jadeite rough by its outer shell.

[0003] Jadeite researchers often pay little attention to the internal fissures of jadeite rough. However, if a high-quality jadeite rough is damaged by a fatal fissure, it cannot be used as a large piece of raw material for later processing, significantly reducing its value. Fractuses in jadeite are mainly caused by the uplift of the jadeite rock due to crustal movement, resulting in compression or stretching under external forces. As the crust continues to rise, the jadeite breaks along these fissures, leading to the disintegration of the jadeite rock into pebbles of varying sizes. Currently, in the jadeite rough trading market, the number and direction of fissures are usually estimated based on the experience of practitioners. Therefore, fissure assessment is highly uncertain and involves significant technical barriers. Typically, after purchasing jadeite rough, it is necessary to cut it open based on the experience of a practitioner to verify the number and direction of fissures. However, if a misjudgment occurs, the economic loss due to the jadeite rough being unable to be processed into large gemstones because of incorrect cutting placement is irreparable. Currently, there is a lack of methods for investigating and analyzing the internal cracks of jadeite rough stones in the buying and selling process, and there are no simple and easy technical means to visually present the internal cracks of jadeite.

Attached Figure Description

[0018] The following sections will describe some specific embodiments of the invention in detail by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0020] Figure 2 This is a cross-sectional view of the external cracks in a jadeite rough stone to be tested, according to an embodiment of the present invention.

[0021] Figure 3This is a schematic diagram of a device for detecting internal defects in jadeite rough based on X-ray detection, provided in an embodiment of the present invention. Detailed Implementation

[0022] like Figure 1 The diagram shown is a flowchart illustrating a method for detecting internal defects in jadeite rough based on X-ray detection, according to an embodiment of the present invention.

[0023] A method for detecting internal defects in jadeite rough based on X-ray detection, comprising at least the following steps:

[0024] S101, X-ray tomography is performed on the jadeite rough sample to be tested to obtain the X-ray tomography results;

[0025] S102, Based on the X-ray tomography results, the cracks in the jadeite rough sample to be tested are analyzed, and the analysis results are generated;

[0026] S103, if the analysis results indicate the presence of cracks, then the characteristic information and location information of the cracks in the jadeite rough to be tested are obtained from the X-ray tomography results to generate crack analysis results; wherein, the characteristic information of the cracks includes at least the complete shape and size of the cracks and the trend of the cracks inside the jadeite rough to be tested.

[0027] S104, Select several scan images related to the fracture from the X-ray tomography results and generate a three-dimensional map of the fracture trend;

[0028] S105, Based on the three-dimensional diagram of the crack trend and the crack analysis results, output the crack assessment results of the jadeite rough to be tested.

[0029] Cracks in jadeite rough are classified as external and internal. Most jadeite rough contains external cracks. When internal cracks in jadeite rough transform into larger cracks, external cracks usually form on the outside of the rough. During later processing, jadeite rough is cut. To increase its value, it is typically cut along the direction of these external cracks. Accurately predicting the direction of these external cracks can significantly improve the economic value of jadeite rough.

[0030] In some special scenarios, the micro-cracks inside jadeite rough also need to be evaluated, because the fewer the micro-cracks inside the jadeite rough, the greater its economic value.

[0031] In S101, X-ray tomography is performed on the jadeite rough sample to be tested according to a preset step size to obtain X-ray tomography results; wherein, the X-ray tomography results include sample chamber view, several cross-sectional views of the sample in the X direction, several cross-sectional views of the sample in the Y direction, and several cross-sectional views of the sample in the Z direction.

[0032] By using different preset step sizes and scanning precision, the trends of external and micro-cracks inside jadeite rough stones can be observed. The X-ray tomography results are three-dimensional images of the jadeite sample being tested.

[0033] For example, when the jadeite rough sample to be tested is subjected to X-ray tomography scanning according to the first preset step size, a three-dimensional map of the external crack trend and the external crack evaluation result of the jadeite rough to be tested are obtained accordingly; and based on the three-dimensional map of the external crack trend and the external crack analysis result, the external crack evaluation result of the jadeite rough to be tested is output.

[0034] When the jadeite rough sample to be tested is subjected to X-ray tomography scanning according to the second preset step size, a three-dimensional map of the internal fracture trend and the internal fracture evaluation result of the jadeite rough to be tested are obtained accordingly; and based on the three-dimensional map of the internal fracture trend and the internal fracture analysis result, the internal fracture evaluation result of the jadeite rough to be tested is output; wherein, the second preset step size is smaller than the first preset step size.

[0035] In steps S102 and S103, based on the X-ray tomography results, the fissures in the jadeite rough sample are analyzed, and analysis results are generated. If the analysis results indicate that no fissures exist, no processing is performed; if the analysis results indicate that fissures exist, the trend and complete shape of the fissures inside the jadeite rough are obtained based on the three-dimensional image of the jadeite sample; the location and size information of the fissures inside the jadeite rough are determined according to the trend and complete shape of the fissures, thereby generating a fissure analysis report.

[0036] Here, no restrictions are placed on the analysis method; it can be based on the image analysis methods used in existing X-ray computed tomography.

[0037] In S104, since the trend of the crack inside the jadeite rough to be tested may not be from one end of the jadeite rough to the other; but rather it may end at a certain position inside the jadeite rough, it is necessary to select several cross-sectional scan images containing the crack from the X-ray tomography results to form a target image sequence; and generate a three-dimensional map of the crack trend based on the target image sequence.

[0038] In S105, based on the three-dimensional diagram of the crack trend and the crack analysis results, the cracks of the jadeite rough to be tested are evaluated according to preset rules, and the crack evaluation results of the jadeite rough to be tested are output.

[0039] This embodiment uses X-ray tomography to scientifically visualize the distribution of cracks inside the jadeite rough sample, and analyzes the characteristic and location information of the cracks to help determine the quality of the jadeite rough sample. This enables qualitative analysis of the jadeite rough and provides a scientific reference for subsequent slicing, design, processing, and value assessment of the jadeite rough, thereby minimizing economic losses in jadeite rough trading.

[0040] In a preferred embodiment of this example, the method further includes: acquiring a target image sequence corresponding to the three-dimensional map of the external crack trend; preprocessing the target image sequence to generate a preprocessed image sequence; magnifying the preprocessed image sequence to obtain a magnified image sequence; selecting several scanned images related to microcracks from the magnified image sequence to generate a three-dimensional map of the microcrack trend; obtaining the feature information and location information of the microcracks in the jadeite rough to be tested based on the three-dimensional map of the microcrack trend, and generating a microcrack analysis result; wherein, the feature information of the microcracks includes at least the complete shape, size, and trend of the microcracks inside the jadeite rough to be tested; and outputting the microcrack evaluation result of the jadeite rough to be tested based on the three-dimensional map of the microcrack trend and the microcrack analysis result.

[0041] For example, the step of preprocessing the target image sequence to generate a preprocessed image sequence includes: performing noise reduction processing on the target image sequence to generate a noise-reduced image sequence; and performing contrast processing on the noise-reduced image sequence to generate a preprocessed image sequence.

[0042] For example, for any target image in a target image sequence: the target image is filtered to generate a denoised image; the contrast of the denoised image is then processed using a tone mapping algorithm to generate a preprocessed image. Thus, combining image filtering and contrast processing allows for the acquisition of more detailed information from the target image.

[0043] This embodiment preprocesses the target image sequence to obtain more detailed information in the target image; by magnifying the preprocessed image sequence, it can further obtain feature information in the preprocessed image, which is beneficial for identifying microcracks; thus, this embodiment combines preprocessing and magnification to improve the accuracy of microcrack identification in the three-dimensional map of external crack trend.

[0044] In another preferred embodiment of this example, the method further includes: acquiring all scan images in the X-ray tomography results; for any two scan images in all scan images: if the difference in the average contrast of the two scan images is less than a first preset threshold and the difference in grayscale values ​​is less than a second preset threshold, then the internal texture of the jadeite rough sample to be tested is determined to be uniform; and the texture evaluation result of the jadeite rough sample to be tested is output.

[0045] Specifically, if the scanned image shows a relatively uniform brightness and contrast, it indicates that the internal uniformity of the jadeite sample is high. As an important evaluation feature for jadeite grading, it can indirectly indicate the quality of the jadeite sample.

[0046] This embodiment determines the uniformity of the internal texture of a jadeite rough sample based on the internal contrast and grayscale value of the scanned image, thereby effectively evaluating the texture of the jadeite rough sample and improving the accuracy of the texture evaluation.

[0047] In another preferred embodiment of this example, the jadeite rough to be tested is obtained by the following method: nanoparticles and barium sulfate are added to an organic solvent and mixed thoroughly to prepare an immersion liquid; the jadeite rough sample is completely immersed in the immersion liquid, and after the immersion time is reached, the soaked jadeite rough sample is taken out of the immersion liquid; the soaked jadeite rough sample is washed with water, and then dried; the dried jadeite rough sample is used as the jadeite rough to be tested.

[0048] Specifically, rare-earth-doped sodium lutetium fluoride nanoparticles and barium sulfate are added to a cyclohexane organic solvent and mixed thoroughly to prepare an immersion liquid; this immersion liquid is a suspension. An appropriate amount of immersion liquid is selected based on the size of the jadeite rough sample to be tested, ensuring that the jadeite rough sample is completely submerged in the immersion liquid.

[0049] It should be noted that the soaking liquid can only flow into the external cracks of the jadeite rough sample, but cannot flow into the micro-cracks of the jadeite rough sample.

[0050] This embodiment improves the fluidity of the soaking liquid in the jadeite rough sample by adding nanoparticles; it also enhances the fluorescence indication effect of the jadeite rough sample in X-ray tomography by adding barium sulfate to the soaking liquid; thus, it enables effective analysis of cracks in the jadeite rough sample and improves the accuracy of crack analysis results.

[0051] In another preferred embodiment of this invention, during the soaking process of the jadeite rough, a preset pressure is applied to the jadeite rough and the soaking liquid; wherein, the preset pressure is 1×10⁻⁶. 4 MPa / m2 -2×10 4 MPa / m 2 The pressurization time for the preset pressure is 30-100 minutes.

[0052] Specifically, a preset pressure is applied to the soaking liquid and the jadeite rough stone in the soaking liquid using a high-pressure liquid injection device; the magnitude of the preset pressure and the pressure application time are determined according to the size of the jadeite rough stone sample and the size of the exposed cracks.

[0053] In this embodiment, pressurization is applied during the soaking process of the jadeite rough stone, which facilitates the flow of the soaking liquid into the interior of the jadeite rough stone along the external cracks. This improves the scanning effect of the jadeite rough stone sample under X-ray tomography, thereby facilitating the detection of cracks in the jadeite rough stone sample.

[0054] The detection method of this embodiment will be described in detail below with reference to specific application scenarios.

[0055] A method for detecting internal defects in jadeite rough based on X-ray detection, comprising at least the following steps:

[0057] S2. Place the jadeite rough sample to be tested into the sample chamber of the scanning device. The size of the sample and the sample chamber determines whether to place one or multiple jadeite rough samples at a time. Set the scanning voltage and scanning current based on the size of the jadeite rough sample.

[0058] S3, perform X-ray tomography on the jadeite rough sample to be tested according to the first preset step size to obtain the X-ray tomography results; based on the X-ray tomography results, analyze the cracks in the jadeite rough sample to be tested to generate analysis results.

[0059] S4. If the analysis results indicate the presence of external cracks, the characteristic information and location information of the external cracks in the jadeite rough to be tested are obtained from the X-ray tomography results to generate external crack analysis results; wherein, the characteristic information of the external cracks includes at least the complete shape and size of the external cracks and the trend of the external cracks inside the jadeite rough to be tested.

[0060] S5. Select several scan images related to the external fracture from the X-ray tomography results to generate a three-dimensional map of the external fracture trend.

[0061] S6. Based on the three-dimensional diagram of the external crack trend and the external crack analysis results, output the external crack evaluation results of the jadeite rough stone to be tested.

[0062] S7, acquire the target image sequence corresponding to the three-dimensional map of the external fracture trend; perform noise reduction processing on the target image sequence to generate a noise-reduced image sequence; perform contrast processing on the noise-reduced image sequence to generate a preprocessed image sequence. Enlarge the preprocessed image sequence to obtain an enlarged image sequence; select several scan images related to the micro-fracture from the enlarged image sequence to generate a three-dimensional map of the micro-fracture trend.

[0063] S8. Based on the three-dimensional map of the microcrack trend, obtain the characteristic information and location information of the microcracks in the jadeite rough to be tested, and generate microcrack analysis results; wherein, the characteristic information of the microcracks includes at least the complete shape and size of the microcracks and the trend of the microcracks inside the jadeite rough to be tested.

[0064] S9. Based on the three-dimensional diagram of the microcrack trend and the microcrack analysis results, output the microcrack evaluation results of the jadeite rough to be tested.

[0065] S10, acquire all scan images in the X-ray tomography results; for any two scan images in all scan images: if the difference in the average contrast of the two scan images is less than a first preset threshold and the difference in grayscale value is less than a second preset threshold, then determine that the internal texture of the jadeite rough sample to be tested is uniform; output the texture evaluation result of the jadeite rough sample to be tested.

[0066] S10: Based on the evaluation results of external cracks, micro-cracks, and texture of the jadeite rough to be tested, the quality grade of the jadeite rough to be tested is determined.

[0067] This invention aims to provide a scientific and visual three-dimensional representation of the internal defects of jadeite rough using X-ray tomography technology. It also provides comprehensive information on the internal defects of jadeite rough, including the presence, number, and three-dimensional orientation of cracks. This provides a scientific reference for the subsequent slicing, design, processing, and value assessment of jadeite rough, minimizing economic losses in the process of buying and selling jadeite rough.

[0068] like Figure 2 The image shown is a cross-sectional view of the external cracks in a jadeite rough stone under test, according to an embodiment of the present invention. Through... Figure 2 It can be seen that the crack characteristics of a certain cross-section of the jadeite rough sample after scanning are known.

[0069] like Figure 3 The diagram shown is a schematic representation of a device for detecting internal defects in jadeite rough based on X-ray detection, according to an embodiment of the present invention.
