Description

gemstone analysis device

The present application relates to gemstone identification, in particular, to an anti-counterfeiting transaction system platform integrating gemstone characteristic value data.

The mainstream commodities in the gemstone industry include four major gemstones, and diamonds, rubies, emeralds and sapphires are the focus of the mainstream market. In recent years, more distinctive stone species have gradually attracted the attention of consumers.

There are many factors that determine the price of a gemstone, the main one being rarity. For example, untreated Kashmir sapphires, Burmese rubies and Colombian emeralds are hard-to-find treasures. Fancy colored diamonds are also notable for their astronomical prices. In addition, gemstone mining, supply chain and even color trends are also key factors in determining value. For example, consumers are increasingly interested in the stories behind gemstones, including origin, mining process and brand philosophy. For a long time, the diamond mining industry has been monopolized by several large companies, and colored gemstones are mainly mined on a small scale. In recent years, the gem mining industry has also gradually changed. More than 20% of the world's production currently comes from several major miners, including emeralds in Zambia and Colombia (Gemfields, Fura Gems, TMC and Esmeraldas Santa Rosa) and rubies in Greenland and Mozambique (True North, Gemfields, Fura Gems). ).

In terms of supply chain, miners generally sell directly through auctions, which affects the business opportunities of downstream gemstone distributors, manufacturers and even retailers. Some large miners are trying to boost consumer confidence will provide transparent information, such as proof of origin and mining stories. For example, companies investing in mining farms also drive the development and employment rate of their communities and improve the lives of local people, which is a marketing strategy to enhance the corporate image.

Transparency of information applies not only to mining and marketing efforts, but especially to the gemstone itself. For example, the Proof of Origin program run by the Gübelin Gem Lab uses blockchain as a tracking tool. The Proof of Origin blockchain is applicable to any type of gemstone, by infusing physical nano-tags into the gemstone, accurately tracking every step of the transaction from the mine close to the gemstone, allowing transparency throughout the gemstone's journey from the pit to the final consumer. However, the disadvantage of this method is that the gem itself must be destroyed, and the technical threshold of the required equipment is too high, so it cannot be popularized for public transactions.

The value of gemstones depends not only on variety, color, and quality, but today's consumers pay more attention to the social responsibility and transparency of the entire transaction process, and expect the purchased products to contribute to the entire industry chain. In addition to the sales model provided by the miners, there is still a lack of a platform that can effectively provide transaction services for general mid-stream and downstream distribution retailers or consumers. The transaction of gemstones is not as good as that of ordinary commodities, which can be purchased on ordinary e-commerce sites. Because of the high unit price of ordinary gemstone products, it is easy to have the problem of authenticity. Therefore, in the transaction process, in addition to the transparent production and sales history, it also requires a technology to effectively verify the authenticity of gemstones. For the average consumer, the technical threshold for verifying gemstone commodities is one of the difficult challenges.

The embodiments of the present application provide a gemstone analysis device. In the gemstone analysis device, a carrying platform is disposed on a substrate module for carrying a tested object. A light-emitting module is disposed on the substrate module and used for providing an input light to the carrying platform. a rotating platform disposed on the substrate On the module, around the carrying platform. A photographing module is disposed on the rotating platform and can rotate with the rotating platform, wherein when the measured object is illuminated by the input light, the photographing module collects an output light refracted or reflected from the measured object. A memory is connected to the camera module and stores the output light as an image of the object under test. A microprocessor, connected to the memory, is used for controlling the carrying platform, the light-emitting module, the rotating platform, and the photographing module.

The microprocessor analyzes the image of the tested object to generate a characteristic value of the tested object.

The gemstone analysis device may further include an interface for connecting to a user equipment; wherein the interface transmits the image of the tested object to the user equipment, so that the user equipment generates a characteristic value according to the image of the tested object.

Wherein the carrying platform can be rotated, so that the tested object is irradiated by the input light at different angles.

The light-emitting module may include at least one of the following: a light-emitting diode module, an infrared light module, an ultraviolet light module, and a laser light module. The light-emitting module is controlled by the microprocessor to dynamically change the wavelength of the input light, so that the photographing module collects images of the tested object corresponding to different wavelengths.

The gemstone analysis device may further include an external lens module, which can be attached to the photography module to generate filter effects. The external lens module includes at least one of the following: a polarizer, a beam splitter, and a color filter. The microprocessor can control the external lens module to select different filters so as to collect images of the tested object corresponding to the different filters.

The carrying platform includes a plurality of rotatable elements, which contact the measured object when the carrying platform places the measured object. The microprocessor controls the rotating elements to drive the measured object to turn over, so as to collect images of the measured object corresponding to different turning angles. The rotating elements may be one of the following: rollers, balls, and gears.

The carrying platform further includes a plurality of jibs, which have elastic force for retracting to the carrying platform, and are used to provide a fixing function when the measured object is placed on the carrying platform. A rotatable element is arranged at the end of each of the booms, and contacts the measured object when fixing the measured object. The rotatable elements are rollers or balls.

The carrying platform further includes an electronic scale for measuring the weight of the measured object.

To sum up, the present application is based on a portable standardized measuring device to measure standardized gemstone characteristic values for gemstone products. The simplification, automation and standardization of the measurement method of gemstone characteristic value, combined with the standard formulation of the unique name of gemstones, realizes a simple and reliable gemstone resume system, and also realizes a fair and open trading basis. Standing on these foundations, we can further build applications and gemstone trading platforms to transform traditional gemstone transactions into online transactions. Therefore, what this application creates is not only a business opportunity for a measuring device, but a business model that can drive the overall gemstone industry, which can promote the economy, activate the market, create job opportunities, and make great contributions to the social industry.

Most of the gemstone identification equipment that exists in the current technology is the analysis or grading of the optical characteristics of gemstones, such as spectral analyzers, refractive index analyzers, and polarization analyzers. In certain materials of gemstones, it is even possible to use a magnetic analyzer to obtain gemstone characteristic values. Although the gemstone identification equipment available on the market today is dazzling, there is a lack of a systematic platform that integrates all the analytical features, so that the gemstones can fully verify the relevant data in the process of trading to distinguish the authenticity.

FIG. 1 is a gemstone trading platform 100 according to an embodiment of the present application. The gemstone trading platform 100 includes multi-layer service devices spanning the upstream and downstream of the network, and can provide complete online trading services for users and merchants all over the world. The gemstone trading platform 100 mainly includes a transaction server 110, which can receive user access requests through the Internet or a global communication system to process transaction transactions. One of the functions of the transaction server 110 is transaction matching. The user can connect to the transaction server 110 through the user equipment 120 to conduct gem transactions. The user equipment 120 may be a smartphone, tablet, laptop, or desktop computer. The user equipment 120 can connect with the transaction server 110 through a specially designed transaction application (APP) or browser, and use various services provided by the transaction server 110 . In addition, the transaction server 110 of this embodiment establishes complete and detailed production and sales history information for all gemstone commodities entering the system, including the situation from the place of origin, processing to mid-stream and downstream supply and shipment. The transaction server 110 also creates standardized gemstone characteristic value 102 files for all gemstone commodities in the system. In general, the characteristics of gemstone commodities include at least various parameters generated under optical analysis, such as reflectivity, refractive index, transparency, uniformity, spectral color, polarization characteristics. For example, some basic objective conditions such as hardness, density and weight can also be listed as one of the gemstone characteristic values 102 . Since there are many ways to measure the eigenvalues of gemstones, in order to make the eigenvalues of gemstones obtained from the above measurements have A standardized database, the present application also proposes a method for measuring the characteristic value of gemstones, and a standardized tool for measuring the characteristic value of gemstones, so that various objective measurement data can be converted into digital information, and the uniqueness of each gemstone can be established in the cloud. The digital fingerprint of the product. On the other hand, the present application also provides a method for verifying the characteristic value of gemstones, so that buyers can use the gemstone characteristic value measuring tool provided by the present application to verify whether the gemstone characteristic value 102 of the gemstone product 140 is consistent with the data stored in the transaction server 110. .

In FIG. 1 , the present embodiment proposes a gemstone analysis device 200 , which can be serially connected to the user equipment 120 , and cooperate with the application software installed on the user equipment 120 to perform feature measurement on the gemstone products 140 held. The gemstone analysis device 200 and the user equipment 120 can be connected by a wire, such as a USB cable or an earphone cable. The gemstone analysis apparatus 200 and the user equipment 120 can also be connected by wireless means, such as Bluetooth (BlueTooth) or wireless local area network (WLAN). After a gem product 140 is produced, a file needs to be created in the transaction server 110 first. The provider of the gemstone product 140 can use the gemstone analysis device 200 to obtain the gemstone characteristic value 102 from the gemstone product 140 , and then log in to the transaction server 110 through the application software of the user equipment 120 . In this way, the gem product 140 has completed the system login, and can be traded on the shelf at any time. When the gemstone product 140 is traded, the buyer user can also use the gemstone analysis device 200 to analyze the gemstone product 140 to verify the gemstone characteristic value 102 stored in the transaction server 110 in advance.

In a further embodiment, the gemstone trading platform 100 of the present application further provides a blockchain 150 that can exchange information with the transaction server 110 or directly exchange information with the user equipment 120 . The blockchain 150 is a decentralized non-repudiation mechanism that enables the registered gemstone characteristic value 102 to be protected against counterfeiting. Blockchain 150 can even further save the complete production and sales history, including supply chain information and transaction records, to prevent illegal money laundering or unidentified goods under a secure and transparent mechanism. Taste. The specific implementation of the blockchain 150 can be jointly participated by all the nodes participating in the transaction all over the world. For example, the blockchain 150 of the present embodiment may include a link network that communicates with each other formed by a plurality of transaction servers 110 all over the world. And all the user equipments 120 participating in the transaction can also be a part of the blockchain 150, and jointly participate in the encryption operation and information storage.

At the time of the transaction, the seller may submit standardized gemstone characteristic values 102 for documentation by the transaction server 110 . Correspondingly, the buyer can obtain the gemstone characteristic value 102 from the gemstone product 140 through the gemstone analysis device 200 , and then connect to the transaction server 110 or the blockchain 150 for verification through the application program in the user equipment 120 . When the gemstone characteristic value 102 obtained by the buyer's gemstone analysis device 200 is consistent with the data in the transaction server 110 or the blockchain 150, the transaction is determined to be established.

Generally speaking, the transaction server 110 of FIG. 1 may be a distributed architecture of multiple web servers, or a virtual application service deployed in a cloud service provider, such as Google or Amazon. The user equipment 120 in FIG. 1 can store the application program described in this embodiment, and execute the measurement method or verification method of the gemstone characteristic value 102 provided by the embodiment of this application. The user equipment 120 can be connected to the gemstone analysis device 200 through wired or wireless means. The connection technology used can be a Universal Serial Port (USB) 2.0, 3.0 or Type C interface, or a Bluetooth interface or a wireless LAN interface. Currently, most of the user equipment 120 basically have a camera module and a lighting lamp, and with the application program proposed in the embodiment of the present application, some characteristic values of the gemstone can be obtained by photographing the gemstone product 140 . Generally speaking, however, the characteristics of the camera module 204 of the user equipment 120 vary with brands, and it is not easy to achieve standardization. For example, when taking a close-up shot, the photographing module 204 is limited in magnification, and it is not easy to take a microscopic picture. In addition, since the lighting lamp and the photographing module 204 are relatively fixed on the body of the user equipment 120, there is a limitation that the angle of the light source cannot be adjusted when they are matched with each other. Therefore, the camera module 204 and the lighting lamp on the user equipment 120 can basically record the most basic appearance and color. Even Further, the user equipment 120 usually includes a positioning system, which can record the current geographic coordinates. Generally, when the user equipment 120 acquires an image, the coordinates of the global positioning system (GPS) can also be recorded in the image at the same time. This information can be included as part of the gemstone characteristic value 102 as reference information for tracking the flow of the gemstone product 140 . Besides, most of the main information in the gemstone characteristic value 102 still relies on the gemstone analysis device 200 according to another embodiment of the present application to complete.

FIG. 2a is a top view of the gemstone analysis device 200 according to the embodiment of the present application. The gemstone analysis device 200 is a portable device that operates independently of the user equipment 120 , and is connected to the user equipment 120 in FIG. 1 through an interface 210 to complete the transmission of information. A rotating platform 218 and a supporting platform 216 are arranged on the substrate module 220 of the gemstone analysis device 200 to form a concentric structure. A photographing module 204 is disposed on the rotating platform 218 and has the capability of microscopic magnification, and can acquire high-magnification microscopic images. For the technical implementation of the photographing module 204, there are already modular products available in the market, and the details of the structure will not be repeated here. A light emitting module 202 is connected to the substrate module 220 and can be implemented by light emitting diodes (LEDs), which can emit light sources of various wavelengths through program control to illuminate the central area of the carrier platform 216 . The carrier platform 216 is designed to hold the gemstone product 140 to be analyzed. For standardization, gemstone product 140 must be detected at a fixed angle or attitude. When a gemstone product 140 is fixed on the carrier platform 216 , the camera module 204 and the light-emitting module 202 can be programmed by the user equipment 120 to perform a dynamic measurement step. The light emitting module 202 can emit the input light 222 , and after irradiating the gemstone product 140 , it is reflected or refracted to form the output light 224 , which is received and recorded by the photography module 204 . The output light 224 can be determined to be refracted light or reflected light according to different angles. For example, when the angle formed by the light emitting module 202 and the photographing module 204 relative to the gem product 140 is less than 90 degrees, it means that the two are basically on the same side, and the collected output light 224 can be regarded as reflected light. In contrast, when the light-emitting module 202 When the camera module 204 is on the opposite side, the output light 224 must be the refracted light generated by the gem product 140 . The information recorded in the above measurement process is a practical indicator for verifying the transmittance of gemstones. The refracted light changes collected from multiple angles can also be a practical indicator for verifying the color uniformity of gemstones. In some types of gemstones, light transmittance and color uniformity can be key parameters in determining value, or one of the basis for computer intelligence to determine the type of gemstone. During measurement, in order to obtain the output light 224 generated by the gemstone product 140 at different angles, the rotating platform 218 where the photographing module 204 is located is a rotatable structure. The rotating platform 218 and the carrying platform 216 have the same circle center, that is, a concentric circle structure. When the gemstone product 140 is placed in the center of the bearing platform 216 , the camera module 204 can acquire the output light 224 generated by the gemstone product 140 irradiated by the input light 222 from different angles along with the rotation of the rotating platform 218 .

In a further embodiment, in order for the gemstone product 140 to receive the input light 222 emitted by the light emitting module 202 at different angles, the carrying platform 216 itself is also a rotatable turntable. When the gemstone product 140 is placed on the supporting platform 216, as the supporting platform 216 rotates, the input light 222 generated by the light emitting module 202 will illuminate different positions of the gemstone product 140, so that the output light 224 changes.

In FIG. 2a, the input light 222 emitted by the light emitting module 202 is variable color, that is, it generates light of different wavelengths. Furthermore, the front of the photographic module 204 can be loaded with an external lens set and an external lens module 240, which includes one or more external lenses, which can be dynamically switched manually or automatically during the measurement process, so that the photographic module 204 records more Optical characteristics for a variety of different conditions. Due to the characteristics of the crystal structure of gemstones, in addition to the color characteristics under ordinary visible light, it will show a unique reaction under a single wavelength of light, which cannot be replicated by man-made objects. Therefore, the verification method of irradiating or filtering with a specific light wavelength (light color) can not only assist in judging the type of gemstone, but also help to identify the authenticity of the gemstone.

The image received by the photographing module 204 can be calculated by the microprocessor 208 to generate the gemstone characteristic value 102 . The gemstone characteristic value 102 may be temporarily stored in the memory 212 or transmitted to the user equipment 120 through the interface 210 . In another embodiment, the gemstone analysis device 200 only transmits the raw image data obtained by the photography module 204 to the user equipment 120, and the user equipment 120 calculates the gemstone characteristic value 102 through a specific application. After receiving or calculating the characteristic value 102 of the gemstone, the user equipment 120 runs the application provided by the embodiment of the present application to connect with the transaction server 110 or the blockchain 150 to complete the steps of measurement or verification.

The gemstone analysis device 200 may include a microprocessor 208 and a memory 212 . The measurement program can be stored in the memory 212 and executed under the control of the microprocessor 208. According to specific steps, the above-mentioned components are used to collect optical images obtained from various angles and different lenses, and further analyze and process them for storage. is the gemstone feature value 102 corresponding to the gemstone product 140 . Finally, it is uploaded to the user equipment 120 through the interface 210 so as to execute further transaction-related applications.

The arrangement position of the components in FIG. 2a is only for illustration, and the hardware layout during actual manufacturing is not limited to the design and shape disclosed in FIG. 2a. For example, the positions of the light emitting module 202 and the photographing module 204 can be interchanged, the light emitting module 202 is connected by the rotating platform 218 to be able to rotate dynamically, and the photographing module 204 is fixedly arranged on the substrate module 220 . The gemstone analysis device 200 may also include further functional modules, such as a touch screen, a human-machine interface, etc., so that the user can realize the gemstone detection function mentioned in the embodiments of the present application even in an offline state. Specific design details are not limited here.

FIG. 2b shows an embodiment of an external lens module 240 . The external lens module 240 is a structure that rotates with the center 248 as the axis, and can be added to the front end of the photographing module 204 . The design concept of this embodiment is that when the external lens module 240 rotates, one of the external lenses is superimposed on the photographic module. 204 in front of the lens, to achieve the effect of adding a lens. The polarizer 242 is designed to be a dynamically rotatable structure, so that the photographing module 204 records the response of the gemstone product 140 to polarized light of different angles. The beam splitter 244 can refract the visible light into a spectral form, so that the photographing module 204 records the optical intensity changes of different frequency bands in the output light 224 . The color filter 246 may filter out specific wavelengths of the output light 224 in order to observe the content of a specific color in the gemstone product 140 . The design of the external lens module 240 shown in FIG. 2b is only one example of various possibilities. There can be more than three types of external lenses. One mode can even be reserved as empty lens, that is, when the external lens module 240 rotates to the empty lens, there is no additional lens in front of the photographing module 204, so as to collect the most original image data.

FIG. 3 is a side view of the gemstone analysis device 200 according to the embodiment of the present application. In contrast to FIG. 2 a , on the substrate module 220 , a rotating platform 218 and a carrying platform 216 are configured to form a coaxial structure, and the two can be rotated on the substrate module 220 respectively. The light emitting module 202 is connected to the substrate module 220 through a bracket 203 , and the photographing module 204 is connected to the rotating platform 218 through a bracket 205 . Considering that the gemstone product 140 is three-dimensional, the position of the light emitting module 202 and the photographing module 204 relative to the gemstone product 140 also needs to consider the height. Therefore, the bracket 203 and the bracket 205 can be designed as telescopic structures with adjustable lengths. When analyzing the gemstone characteristic value 102, the length of the support 203 and the support 205 can be extended and retracted automatically or manually according to the size and height of the gemstone product 140, so that the input light 222 is irradiated to the appropriate position on the gemstone product 140, and the photographic model Group 204 captures output light 224 from appropriate locations on gemstone product 140 . For example, when the light emitting module 202 and the photographing module 204 overlap due to the rotation of the rotating platform 218, theoretically, they cannot overlap in space. Therefore, by adjusting the bracket 203 and the bracket 205, the light emitting module 202 The height of the camera module 204 is staggered, so that the two can be overlapped at the same angle at the same time.

The gemstone analysis device 200 further includes a casing 250 , which can cover the substrate module 220 during use, can isolate external light interference, and can protect internal components and assist in fixing the gemstone product 140 . Likewise, the arrangement positions of the components in FIG. 3 are only for illustration, and the actual hardware layout during manufacture may vary. The light emitting module 202 in the figure itself may be a combination of various light source modules, such as a light emitting diode (LED) module, an ultraviolet light module, an infrared light module, or a laser light module. The light-emitting module 202 can selectively emit input light 222 of different wavelengths according to the type of gem product 140 or analysis requirements through program control, so that the photographic module 204 receives the corresponding output light 224 to obtain accurate light. Analyze the results. The modules described in the light-emitting module 202 can be combined with modular and small-sized component modules with the current technology. The motor (not shown) used for the relative rotation of the carrying platform 216 and the rotating platform 218 may be a stepping motor or an ultrasonic motor. The camera module 204 itself may be a camera module that operates dynamically according to program control. Today's technology has made it possible to obtain modular and tiny camera modules, which can not only perform microscopic magnification photography, but also dynamically adjust the focus. The design structure of the brackets 203 and 205 can refer to the known telescopic mechanism, and the telescopic length can be controlled by a program. And the height values of the input light 222 and the output light 224 can be incorporated into the gemstone characteristic value 102 together, so that the parameters of the measurement process have a consistent standard.

FIG. 4 is a top view of an embodiment of a carrying platform 416 of the present application. When analyzing the gemstone product 140, considering that the gemstone product 140 itself is a three-dimensional structure, the conventional identification method is to manually rotate the gemstone product 140 and observe it with the naked eye. This embodiment further provides a mechanism for automatically rotating the gemstone product 140, so that the camera module 204 can further obtain image information from different angles. The carrier platform 216 shown in Figure 3 is itself a rotatable platform. The user can manually determine the placement angle when placing the gemstone product 140 on the carrying platform 216 . The bearing in Figure 4 The carrier platform 416 is further provided with a plurality of rollers 410 , when the carrier platform 416 carries the gemstone product 140 , these rollers 410 contact the gemstone product 140 . When the roller 410 is rotated under the program control, the gemstone product 140 can be rotated, thereby realizing automatic control of the lighting angle and the observation angle of the gemstone product 140 . A motor (not shown) can be configured inside the carrying platform 416 to control the rotation of the rollers 410 . The rotation angle can be controlled by the microprocessor 208 and the program in the memory 212 . The structure shown in FIG. 4 is only an example, and the form and quantity of the rollers 410 are not limited to this during actual manufacturing. For example, the rollers 410 on the carrying platform 216 can also be in the form of four to six balls or gears, so that the gemstone product 140 can rotate in any direction.

FIG. 5 is a side view of the embodiment of the carrier platform 416 of FIG. 4 . The carrying platform 416 includes a plurality of rollers 410 as a mechanism for rotating the gemstone product 140 when the carrying platform 416 carries the gemstone product 140 . The roller 410 can be a roller type, fixed on the upper surface of the bearing platform 416 with a bearing, or a universal ball, fixed on the upper surface of the bearing platform 416 by means of groove embedding, forming a bearing platform that can rotate the gemstone product 140. As for the implementation of the rotation method, the carrying platform 416 may include a driving module 500 . The roller 410 can be connected with the driving module 500 by means of gears or belts. The driving module 500 can receive the electronic control signal to individually control the rotation angle of each roller 410 , so as to rotate the gemstone product 140 carried thereon. In many cases, in order to obtain the optical features of the gemstone product 140 in finer detail, it is necessary to flip the gemstone product 140 on the normal vector perpendicular to the lens, that is, on the horizontal axis parallel to the platform surface. In this embodiment, the design of adding the roller 410 to the carrying platform 416 can achieve this function.

In a further embodiment, some mechanisms for fixing objects may be configured on the carrying platform The carrying platform 416 , for example, a plurality of suspension arms 502 with rollers 504 at the ends have elastic force to be retracted toward the carrying platform. When the gemstone product 140 is placed on the carrier platform 416, it can be accessed from above the carrier platform 416 Downward pressure is applied to hold the gemstone product 140 in the middle so as not to leave the carrier platform 416 due to gravity or vibration. The hanging arm 502 is in contact with the gemstone product 140 through the roller 504 . When the roller 410 rotates to drive the gemstone product 140 to rotate, the roller 504 can be driven passively without hindering the movement of the gemstone product 140 . The embodiments of the present application only provide a fixed concept, and do not limit the design manner of its physical structure. For example, the rollers 504 may also be in the form of universal balls. In a state where no items are placed on the carrying platform 416, the arm shaft 506 of the boom 502 can be configured with spring stress to allow the rollers 504 to be retracted toward the carrying platform 416 for convenient storage.

In an even further embodiment, it is contemplated that the carrying platform 416 fully carries the weight of the gemstone product 140 . An electronic scale (not shown) may be further implemented in the carrying platform 416 to also include the weight of the gemstone product 140 as an item in the gemstone characteristic value 102 .

In a further embodiment, since the photographing module 204 basically captures images of gemstone products from more than 140 angles, the back-end processor can easily determine the three-dimensional size and shape of the gemstone. In other words, gemstone characteristic values may include the size and shape of the gemstone product 140 . If the shape and weight of the gemstone product 140 can be calculated, the density can be further calculated and recorded as an item in the gemstone characteristic value 102 , which will be a useful parameter for the verification of the gemstone product 140 in future transactions.

FIG. 6 is an embodiment of adjusting observation parameters by the gemstone analysis device 200 of the present application. Through the embodiments of FIGS. 2 a to 5 , it is explained that the novel gemstone analysis device 200 can adjust various parameters to observe various possibilities. For example, crystalline gemstones belong to a crystal structure, so in the traditional identification process, finding out the direction of the optical axis is the most basic step. Therefore, it is necessary to constantly rotate the gemstone and observe the changes in the optical characteristics. Through the gemstone analysis device 200 proposed in the present application, this step can be completed automatically and intelligently. Assuming that the input light 222 is the fixed reference direction, Defined as the x-axis, the output light 224 collected by the camera module 204 moves on the x-y plane, and its angle is defined as A1, which is used to adjust the angle of the output light 224 relative to the input light 222 . The spin performed when the bearing platform 216 carries the gemstone product 140 is the angle A2 on the z-axis, which is used to adjust the surface of the gemstone product 140 irradiated by the input light 222 . The roller 410 shown in FIG. 5 can further make the gemstone product 140 be turned sideways by an angle A3. By adjusting A2 and A3, the angle at which the gemstone product 140 can be observed basically no longer has a dead angle. Combined with the change of the angle A1, the possibility of shooting the input light 222 from any angle and observing the output light 224 from any angle can be realized. The embodiment of FIG. 6 provides only one possibility for an angle change configuration. In actual production, it is not limited to this. For example, through the control of the roller 410 in FIGS. 4 and 5 , the gemstone product 140 can also be directly flipped in the x-axis direction in FIG. 6 . If the variation of adjusting the heights of the light-emitting module 202 and the photographing module 204 in FIG. 3 is added to the embodiment, a richer parameter combination variation can be generated. For example, the controllable parameters provided in the current embodiment have at least included the weight of the gemstone product 140 , the rotation angle A2 of the bearing platform 216 , the rotation angle A1 of the rotating platform 218 , and the heights of the light emitting module 202 and the photographing module 204 . Adjustments include the type and wavelength of light output by the light-emitting module 202 , the selection of filters in the external lens module 240 , and the angle A3 at which the gemstone product 140 is flipped by the roller 410 . In this way, it is not only possible to maximize the detail of the gemstone characteristic values 102 that can be collected, but also to formulate objective measurement standards that are universally applicable.

The value of a gemstone comes from its beauty and rarity. The beauty of a gemstone is generally composed of factors such as its color, luster, transparency, and special optical effects. The color of gemstones can be divided into two categories: colored and colorless. Colored gemstones require bright, pure and uniform colors. For example, high-grade rubies, sapphires and emeralds have pure and bright red, blue and green respectively. Colorless diamonds can be processed to display different spectral colors called fire. Some gems do not have vivid colors, but they have strong Glossy and high transparency. Some gemstones can be skillfully processed to produce a cat's-eye-like light band or multiple intersecting radial bright bands, similar to the beautiful starlight, which are all manifestations of beauty. On the other hand, the rarity of a gemstone is also a key factor in determining its value. For example, as rare as amethyst, it was only found in Europe at first and was regarded as a treasure with high price. Later, a large number of amethyst deposits were discovered in Brazil, and the price also fell sharply. The quality is as rare as emerald, and its mineral is beryl. Beryl has a wide output, large reserves and low price. However, there are fewer varieties of emeralds with bright green color and high quality, and the price is high.

The gemstone analysis device 200 of the present application is designed with a standardized measurement method in a portable device, which is easy to carry, and everyone can become a professional gemstone appraiser with one machine. Since the gemstone characteristic value of each gemstone product is usually a series of numbers that are difficult for users to remember, a popular naming system is needed. In a further embodiment, in order to facilitate users to browse and trade gemstone products on the gemstone trading platform 100, the gemstone trading platform 100 provides a gemstone naming mechanism, which can generate an entire network for the gemstone product according to the uploaded gemstone characteristic value. Unique and human-readable name. By measuring the reflectivity, refractive index, spectral color, polarization characteristics, three-dimensional size, weight and other characteristics of gemstones at multiple angles through standardized steps, the gemstone analysis device 200 can generate readable descriptions of gemstones, such as color tone grade, color The purity grade, surface gloss grade, and transparency grade are used as the material for gem naming. For example, the gemstone trading platform 100 describes gemstones with various properties and grades based on these characteristic values. Transparency is light transmittance, which can be calculated from the refractive index, and can include, for example, but not limited to, high light transmittance, medium light transmittance, and low light transmittance. Color purity is uniformity, which can be judged from the degree of color variation from multiple angles. The less variation, the purer the color and the better the uniformity. The color tone can be roughly divided into, for example, but not limited to, red, orange, yellow, green, blue, indigo, purple, black, and brown, and further divided into color density, such as but not limited to dark, medium, and light. For example dark green, medium red, light blue. Surface gloss is a description of reflectance, which can be abbreviated as high-gloss, low-gloss, or haze depending on the degree. The shape of gemstones can also be roughly classified according to the three-dimensional structure, such as but not limited to square, round, long, flat and so on. The weight of the gemstone can also be simply graded, such as but not limited to light, feather, medium, heavy and so on. The gem name can be optionally matched with information such as gem type, turner, and/or origin, and a check suffix is attached at the end to enhance the uniqueness of the entire network. To sum up, the gemstone trading platform 100 can generate the unique gemstone name of the gemstone product, which is arranged and combined by the above-mentioned various characteristic descriptions to become a name that is unique in the whole network and readable by the user. The check tail code can be a group of numbers obtained by performing hash operation (HASH) or redundancy check operation (CRC) from the binary value of the gemstone characteristic value, and is not limited to three digits, four digits or five digits. number.

Possible names for gemstone products listed on gemstone trading platform 100 are shown by way of example in the table below.

FIG. 7 is a flow chart of gemstone analysis according to an embodiment of the present application. In step 701, the measurement parameters are gradually adjusted. The controllable measurement parameters include at least the arrangement and combination of the following variables: the rotation angle of the bearing platform 216 (the range can be 0-359 degrees), the rotation angle of the rotating platform 218 (the range can be 0-359 degrees) 359 degrees), the height of the light-emitting module 202 and the photographing module 204 (the range is proportional to the height of the gemstone), the type or wavelength of light output by the light-emitting module 202 (ranging from infrared, visible, to ultraviolet), in the external lens module 240 The filters used (three in Figure 2b), and the angle at which the gemstone product 140 is flipped by the roller 410 (which can range from 0-359 degrees). All ranges of permutations and combinations yield hundreds of possibilities. Therefore, in the actual operation, for the sake of timeliness, a wider step series can be used, for example, a measurement is performed every 30 degrees of rotation, or the wavelength range selected by the light-emitting module is cut into three to seven main colors as the representative. Can.

In step 703, the gemstone product is illuminated according to the measurement parameters adjusted each time, and the output light generated by the reflection or refraction of the gemstone product is collected. The original format of the collected data can be image files or video files.

In step 705, it is determined whether all the step-by-step adjustments and measurements of the planning range are completed. If not, proceed to step 701 recursively. If the range of all parameter permutations and combinations is completed, the next step 707 can be performed.

In step 707 , the weight of the gemstone product is obtained from the electronic scale in the carrying platform 216 . Because there are significant differences in the size of gemstone products, ranging from several kilograms to as small as several carats. Therefore, the gemstone analysis device 200 proposed in the present application can be introduced into a variety of different models, so as to be suitable for gemstone products of different grades.

In step 709, according to all the data collected after gradually adjusting the measurement parameters, and the weight of the gemstone product, a gemstone characteristic value unique to the gemstone product is generated. The image files collected from the photographing module 204 must be analyzed and processed before being converted into feature values. For example, the response graph that correlates the brightness in the image to various angle parameters, the ratio of the image color to the wavelength of the light source, the spectrum table produced by the beam splitter, etc. This embodiment does not limit the types of eigenvalues that can be generated here. Because the gemstone analysis device 200 has used a set of standard laboratory-level qualitative and quantitative analysis methods to collect all possible data, and the subsequent analysis and conversion of characteristic values can be arbitrarily matched according to the actual gemstone type and technical requirements. The resulting gemstone characteristic value will be like a fingerprint, and each gemstone product is unique and cannot be repeated. As for the step of generating the characteristic value of the gemstone, the microprocessor 208 of the gemstone analysis device 200 can perform it according to the original image, or the gemstone analysis device 200 uploads the original image to the user equipment 120, and then the user equipment installs the original image.

In step 901, the measurement step as shown in FIG. 7 is performed, measurement parameters are set, optical characteristics of the gemstone product to be traded are collected, and a gemstone characteristic value is generated. In step 903, a gemstone trading platform is connected, and the product history corresponding to the characteristic value of the gemstone is queried on the gemstone trading platform. Since the characteristic value of the gemstone is unique and cannot be replaced, the recalled product resume can be used by traders Verify that it is genuine and make a reliable transaction. In the embodiment of the first step, after the transaction is successful, the personnel, time and place data of the transaction process will also be uploaded to the gemstone trading platform 100 and added to the product history of the gemstone product.

FIG. 10 is a flow chart of evaluation in an embodiment of the present application. Because the price of a gemstone is related to its beauty, rarity, weight, workmanship, purity, origin, international certificates, etc. In a further embodiment, since the gemstone trading platform 100 of the present application can finally grasp the big data of most gemstones after promotion, the evaluation ability can also be generated according to the rarity of the gemstone's characteristic value. In step 1001, the gemstone trading platform 100 can collect market price information of multiple gemstone products at any time during the transaction process. After the gemstone characteristic value of a gemstone product is uploaded to the gemstone trading platform 100, the current market price, such as a bid price or a transaction price, may also be uploaded. In step 1003, the gemstone trading platform may analyze the correlation between gemstone characteristic values and market prices of multiple gemstone products, and establish a correlation model. For example, the gemstone trading platform 100 performs a linear regression analysis corresponding to the market prices of a large number of gemstone products and the corresponding gemstone characteristic values, which can be used to predict which price range a newly uploaded gemstone characteristic value falls within, so as to provide consumers with fairness and reasonableness. price advice. The mechanism of deep learning can also be applied here to model the correlation between gemstone eigenvalues and market prices. In the foregoing embodiments, it has been explained that the gemstone characteristic value is not a single value, but includes various types of values measured under various conditions. Therefore, it can be understood that the method of establishing the price correlation model can be, but is not limited to, the analysis generated for one of multiple characteristic values alone, or the comprehensive correlation analysis generated for the arrangement and combination of multiple characteristic values. In step 1005, the gemstone trading platform 100 can analyze the estimated value of the newly uploaded gemstone product from the gemstone characteristic value of the newly uploaded gemstone product according to the correlation model. For example, the gemstone trading platform 100 can search for other gemstone products with similar characteristic values from the database according to the newly uploaded gemstone characteristic value, and store the searched out gemstone products. The historical prices of gemstone products are listed as a reference for valuation. Furthermore, the gemstone trading platform can train an intelligent judgment model to judge the degree of beauty and rarity from the characteristic value of gemstones to give the estimated value.
