[0045] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0046] At present, the jewelry terminal is used to display and sell jewelry and related accessories, and is gradually promoted and used in various places. The existing jewelry terminal does not have the function of detecting and identifying jewelry, which affects the application of the jewelry terminal. Therefore, the present inventor believes that if the jewelry terminal has a low-cost and easy-to-operate jewelry detection function, the jewelry terminal can be better promoted and applied. For this reason, the present inventor provides the following embodiments:

[0047] Referring toFigure 1 is a flowchart of a jewelry detection method of a jewelry terminal provided in an embodiment of the present application. The method is performed by the jewelry terminal, specifically by a controller of the jewelry terminal. The method comprises steps S10 to S16:

[0048] S1, when detecting that the jewelry is placed on the detection station of the jewelry terminal, controlling the display of the jewelry terminal to display a detection scheme option to the user for selection and confirmation; the detection scheme option includes a jewelry detection instrument detection scheme;

[0049] S2, after the user selects the jewelry detection instrument detection scheme, sequentially detecting the jewelry by the various jewelry detection instruments provided in the jewelry terminal, and saving each detection result; the detection result includes a jewelry detection map;

[0050] S3, sending all the detection results of the jewelry to an analysis device of a detection analyst for analysis and arrangement by the detection analyst;

[0051] S4, receiving the analysis and arrangement result returned by the analysis device, and controlling the display of the jewelry terminal to display the analysis and arrangement result to the user.

[0052] In this embodiment, the jewelry terminal is provided with various jewelry detection instruments (such as energy dispersive X-ray fluorescence spectrometer, Fourier transform infrared spectrophotometer, laser Raman spectrometer, etc.), which can be arranged in a circular ring. The detection station of the jewelry terminal is a movable tray. When the corresponding jewelry detection instrument is needed to detect the jewelry on the tray, the driving device provided in the jewelry terminal can be used to drive the tray to move to the corresponding position, so that the corresponding jewelry detection instrument can detect the jewelry on the tray. By setting multiple jewelry detection instruments to sequentially and automatically test the jewelry, the accuracy of jewelry detection can be improved. Among them, the jewelry terminal obtains the jewelry detection map of each jewelry detection instrument according to the detection data of the jewelry detection instrument.

[0053] In the embodiment, when the user needs to detect the jewelry, the user can place the jewelry on the detection work station of the jewelry terminal, when the jewelry is detected to be placed on the detection work station of the jewelry terminal, the display of the jewelry terminal is controlled to display the detection scheme options to the user; when the user selects the jewelry detection instrument detection scheme, the jewelry is sequentially detected by the various jewelry detection instruments provided by the jewelry terminal, and each detection result is saved; the detection results of the jewelry are sent to the analysis equipment of the detection analysis personnel for analysis and arrangement by the detection analysis personnel; the analysis and arrangement results returned by the analysis equipment are received, and the display of the jewelry terminal is controlled to display the analysis and arrangement results to the user. As can be seen, the embodiment can enable the gradually widely used jewelry terminal to have the jewelry detection function, so that the user can detect the jewelry through the gradually widely used jewelry terminal, which is convenient to use, so as to greatly facilitate the jewelry detection needs of the user. At the same time, since the jewelry terminal has the above-mentioned jewelry detection function, the jewelry terminal can be better popularized and applied.

[0054] As another jewelry detection scheme, the detection scheme options further include: a quick detection scheme; the method further includes:

[0055] S10, when the user selects the quick detection scheme, the light source device irradiates the jewelry on the detection work station of the jewelry terminal with light of a first light intensity, and a first light intensity image of the jewelry is obtained by the camera with preset shooting parameters.

[0056] The light source device can be one or more LED lamps provided in the jewelry terminal and aligned with the detection work station. The light source device works according to a preset power and emits light of a first light intensity. The detection work station can be a jewelry detection table provided in the jewelry terminal. In addition, the shooting parameters can be pre-set when the jewelry terminal is shipped, or can be updated through cloud upgrade. The shooting parameters can include shutter, aperture, ISO, EV value and the like. Herein, no specific limitation is made.

[0057] S11, the light source device irradiates the jewelry on the detection work station with light of a second light intensity, and a second light intensity image of the jewelry is obtained by the camera with the shooting parameters.

[0058] The second light intensity can be stronger than the first light intensity, or weaker than the first light intensity, but the two are different.

[0059] S12, a first image area of the jewelry is extracted from the first light intensity image, and a second image area of the jewelry is extracted from the first light intensity image.

[0060] Exemplarily, the image region of the jewelry can be extracted from the relevant image by image processing technology of image feature extraction. For example, the image contour in the relevant image is extracted first, and then image contour analysis is performed to determine that the image region in the image contour is the image region of the jewelry.

[0061] S13, calculating the luminance average value of each pixel of the first image region and the second image region.

[0062] Specifically, the luminance value of each pixel in the first image region is obtained, and the luminance value of each pixel in the second image region is obtained. At this time, the luminance average value of the pixel of the first image region and the second image region can be calculated by using the two luminance values of the pixel. The luminance value average calculation is performed pixel by pixel, so as to calculate the luminance average value of each pixel of the first image region and the second image region.

[0063] S14, according to the difference of the luminance average value of each pixel of the two, the jewelry in the image is blocked, and each part of the jewelry is obtained by blocking.

[0064] Exemplarily, the step S14 comprises:

[0065] S140, comparing the difference between the luminance average value of each adjacent pixel of the two;

[0066] S141, if the difference is less than a preset threshold, the region where the pixel corresponding to the difference is located is the same part of the jewelry; if the difference is greater than the preset threshold, the region where the pixel corresponding to the difference is located is the remaining part of the jewelry

[0067] In the embodiment, the inventors find that, in order to avoid the identification error of jewelry segmentation (for example, the light source device is one LED lamp, the placing position of the jewelry on the detection station is not opposite to the LED lamp, but deviates from the LED lamp, and under certain light intensity of the LED lamp, due to the distance and the irradiation angle of different parts of the jewelry relative to the LED lamp, the reflection intensity of different material parts of the jewelry is basically the same, and generally, the reflection intensity of different material parts of the jewelry is different under the same light intensity at the same position), the embodiment irradiates the jewelry twice with light of different intensities, then calculates the average brightness of the pixels of the images under the light of different intensities, so as to reflect the average reflection intensity of different parts of the jewelry under the light of different intensities (because the reflection intensity of different material parts of the jewelry is basically the same under a certain light intensity, and when the light intensity changes, due to the different reflection rates of different materials, the parts of the jewelry with different materials but basically the same reflection intensity will have obvious difference in reflection intensity), and then the average reflection intensity is used to reflect the parts of the jewelry with different materials, so that the above-mentioned identification error of jewelry segmentation can be avoided, and the parts of the jewelry in the image can be accurately identified.

[0068] S15, calculating the average difference value of the pixel brightness of each part of the jewelry in the two, calculating the ratio of the average difference value of the pixel brightness of each part of the jewelry to the light intensity difference value of the first light intensity and the second light intensity, and calculating the average color value of the pixels of each part of the jewelry.

[0069] S16, identifying the material types of each part of the jewelry according to the ratio of the average difference value of the pixel brightness of each part of the jewelry to the light intensity difference value and according to the average color value of the pixels of each part of the jewelry.

[0070] As an example, the step S16 includes:

[0071] According to the ratio of the average difference value of the pixel brightness of each part of the jewelry to the light intensity difference value and according to the average color value of the pixels of each part of the jewelry, the material types of each part of the jewelry are identified based on the mapping relationship among the preset ratio of the pixel brightness difference value to the light intensity difference value, the average color value of the pixels and the material types.

[0072] It should be noted that the inventors have found that the same jewelry generally uses only one or a few materials (for example, the materials of the jewelry of jade inlay gold are Hetian jade and pure gold), and the reflectivity characteristics of the materials used in the same jewelry are generally different, so in step S15, the different material parts of the jewelry can be distinguished by the reflectivity of the different materials of the jewelry. However, in step S15, only the different material parts of the jewelry are preliminarily partitioned, and the materials of the different parts of the jewelry can be accurately obtained. Because the types of materials of the jewelry are various, the reflectivity of the different materials of the jewelry may be basically the same. Therefore, only judging the reflectivity of the materials cannot accurately determine the specific material type of the jewelry. Therefore, in this step, the inventors creatively use the following two simple analysis parameters to accurately determine the specific material of the jewelry: the ratio of the pixel brightness difference value to the light intensity difference value, and the average color value of the pixel. The inventors have found that the materials used in the jewelry can be divided into various colors, and the ratio of the reflectivity difference value to the light intensity difference value of the materials under each color is often different. Therefore, as an image parameter representation of visual technology, the ratio of the pixel brightness difference value to the light intensity difference value and the average color value of the pixel can be used to accurately determine the material of the jewelry. It should be noted that by calculating the average color value of the pixel under two different light intensities, the deviation of the pixel color value under certain light intensity (for example, the deviation of the pixel color value under high light intensity or low light intensity) can be avoided, so that the identification and detection of the material of the jewelry are more accurate. It can be understood that the first light intensity and the second light intensity can be two different normal light intensities, and the two light intensities cannot be too weak or too strong.

[0073] Specifically, the mapping relationship among the ratio of the pixel brightness difference value to the light intensity difference value, the average color value of the pixel, and the material type is pre-set, which can be pre-set according to the experience value by testing a large number of samples of different jewelry materials in advance. In this way, when the ratio of the average difference value of the pixel brightness of each part of the jewelry to the light intensity difference value and the average color value of the pixel of each part of the jewelry are obtained, the material type of each part of the jewelry can be identified according to the mapping relationship.

[0074] In the embodiment of the present application, when jewelry detection is needed, light rays with different light intensities are sequentially emitted to jewelry at a detection station of a jewelry terminal to obtain two jewelry images; two image regions of the jewelry are extracted from the two jewelry images; the average brightness of each pixel of the two image regions of the jewelry is calculated, and the jewelry is blocked according to the average brightness to obtain each part of the jewelry; the brightness difference of each pixel is calculated, the ratio of the brightness difference of each pixel to the light intensity difference between the first light intensity and the second light intensity is calculated, and the average color value of each pixel is calculated; and the material type of each part of the jewelry is identified according to the calculated parameters. As can be seen, the embodiment of the present application can enable the gradually widely used jewelry terminal to have a jewelry detection function. The jewelry terminal uses the image processing technology specific to the embodiment of the present application to realize jewelry detection, so that users can perform jewelry detection through the gradually widely used jewelry terminal. The jewelry terminal does not need to be equipped with a special jewelry detection instrument, and users do not need to entrust professional jewelry detection agencies for detection, so as to reduce the cost of jewelry detection and greatly facilitate the jewelry detection needs of users. At the same time, since the jewelry terminal has the above-mentioned jewelry detection function, the jewelry terminal can also be better promoted and applied.

[0075] In summary, the embodiment of the present application only needs to set a light source device and a camera on the jewelry terminal, and uses visual technology to calculate the pixel brightness and color value of the jewelry images obtained by shooting under different light intensities through a simple calculation method, so as to accurately identify the material of the jewelry according to these parameters. The entire process does not need to use complex image processing algorithms, requires very few computing resources, and does not need the jewelry terminal to be equipped with a high-end processor and complex image processing algorithms. Therefore, the use cost of the jewelry detection function of the jewelry terminal of the embodiment of the present application is very low, and the detection accuracy of the jewelry material is also relatively good.

[0076] In the above embodiment, further, after the jewelry is blocked according to the difference between the average brightness of each pixel of the two image regions to obtain each part of the jewelry, the method further comprises:

[0077] calculating the image region width and the image region length of each part of the jewelry;

[0078] judging whether the image region width is less than a preset width threshold value and whether the image region length is greater than a preset length threshold value;

[0079] obtaining the damage condition of the jewelry according to the judgment result; wherein if both are true, it is determined that the part of the jewelry has scratches; otherwise, it is determined that the part of the jewelry does not have scratches.

[0080] Specifically, if a scratch appears on the surface of a certain material part of the jewelry (the scratch is generally small), the reflective intensity of the part with the scratch and the rest of the material is different, that is, the average brightness of the two places is different, so that the part with the scratch is separately blocked. Due to the scratch, the material of the part with the scratch cannot be accurately analyzed, so in the embodiment of the application, when it is determined that the surface of the jewelry has a scratch, the small part with the scratch can not be subjected to the jewelry material detection method of the above-mentioned embodiment of the application for material detection, thereby avoiding affecting the detection accuracy of the jewelry material.

[0081] In the above embodiment, further, after the damage condition of the jewelry is obtained according to the judgment result, the method further comprises:

[0082] According to the material types of the parts of the jewelry and the damage condition of the jewelry, a detection report of the jewelry is generated, and display on the screen of the jewelry terminal is controlled;

[0083] In response to the instruction of generating a submission code issued by the user to the jewelry terminal after checking the detection report, a submission code is generated according to the material types of the parts of the jewelry and the damage condition of the jewelry; the submission code contains the following information: the material types of the parts of the jewelry, the damage condition of the parts of the jewelry;

[0084] The submission code is sent to the mobile phone of the user, so that the mobile phone generates a corresponding jewelry submission scheme according to the submission code; the jewelry submission scheme includes: the material types of the jewelry to be submitted, the estimated cost of the jewelry to be submitted.

[0085] In the embodiment, after the material types of the parts of the jewelry and the damage condition of the jewelry are identified, the user can consider whether the jewelry needs to be submitted according to the actual situation (for example, the user cannot determine the result after checking the detection report, needs to issue a certificate for a valuable gemstone, generates a submission code, and finally hands it over to a professional jewelry detection agency for more comprehensive and accurate jewelry detection), so as to further detect and maintain the jewelry.

[0086] Referring to Figure 2 is a structural schematic diagram of a jewelry detection device of a jewelry terminal provided by an embodiment of the application. The jewelry detection device comprises:

[0090] A receiving and displaying module 4 is configured to receive an analysis and arrangement result returned by the analysis device, and control a display of the jewelry terminal to display the analysis and arrangement result to the user.

[0091] In the embodiment, when a user needs to detect jewelry, the user can place the jewelry on a detection station of the jewelry terminal, and when the jewelry is detected to be placed on the detection station of the jewelry terminal, a display of the jewelry terminal is controlled to display detection scheme options to the user; after the user selects a jewelry detection instrument detection scheme, the jewelry is sequentially detected by various jewelry detection instruments provided on the jewelry terminal, and each detection result is saved; all the detection results of the jewelry are sent to an analysis device of a detection analyst for analysis and arrangement by the detection analyst; an analysis and arrangement result returned by the analysis device is received, and a display of the jewelry terminal is controlled to display the analysis and arrangement result to the user.
