Description

Technical Field

[0001] The present invention belongs to the technical field of data management, and in particular relates to a method and system for tracing and managing artworks. Background Art

[0002] Before an artwork is auctioned, it is often necessary to authenticate and trace the artwork to ensure its reliability. Specifically, in the invention patent application CN202210455825.7 "Data processing method, device, computer equipment, storage medium and computer program product", real-time electronic transaction authentication metadata is used to perform risk matching on the real-time electronic transaction authentication metadata to obtain risk matching results, so that transaction risks can be promptly prompted. However, the following technical problems exist: Artworks often have multiple feature points. Therefore, during traceability management, if traceability management cannot be performed based on the matching of feature points of artworks at different circulation nodes in the circulation process, the accuracy of the traceability management results cannot be guaranteed.

[0003] In response to the above technical problems, the present invention provides a method and system for artwork traceability management. Summary of the invention

[0004] To achieve the purpose of the present invention, the present invention adopts the following technical solutions: According to one aspect of the present invention, a method for tracing and managing artwork is provided.

[0005] A method for tracing the provenance of artworks, specifically comprising: S1 obtains the circulation nodes of the artwork in the traceability process, determines the artwork images of different circulation nodes, and determines the recognition accuracy of different circulation nodes based on the angle of the artwork image and the distribution of feature points of the artwork images at different angles; S2: When there is no circulation node whose recognition accuracy rate does not meet the requirement, based on the recognition accuracy rates of different circulation nodes, it is determined that the reliability of the traceability recognition process of the artwork meets the requirement, and then proceed to the next step; S3 determines the recognition processing order of different circulation nodes based on the recognition accuracy of the circulation nodes, and performs traceability recognition processing of different circulation nodes in the recognition processing order until the circulation nodes whose recognition matching coefficients do not meet the requirements are determined or all the circulation nodes are determined by matching the artwork images at different angles in the circulation nodes with the preset feature points of the artworks; S4: When there is no circulation node whose identification matching coefficient does not meet the requirements, the identification matching coefficients and identification accuracy rates of different circulation nodes are used to determine whether the accuracy of the traceability result of the artwork meets the requirements.

[0006] The beneficial effects of the present invention are: 1. The traceability identification processing of different circulation nodes is carried out in the order of identification processing, thereby realizing the traceability identification processing of different circulation nodes from the perspective of the accuracy of the identification processing of different circulation nodes, and also laying the foundation for determining the judgment method of differentiated traceability results according to the matching situation with the preset feature points of the artwork, thereby improving the accuracy of the traceability results and the efficiency of the identification processing when there are abnormalities.

[0007] 2. Use the recognition matching coefficients and recognition accuracy rates of different circulation nodes to determine whether the accuracy of the artwork's traceability results meets the requirements. This not only takes into account the recognition matching conditions of different circulation nodes, but also the recognition accuracy of different circulation nodes. This enables an accurate assessment of the accuracy of the artwork's traceability results from multiple angles, thus ensuring the reliability of the artwork's traceability results.

[0008] A further technical solution is that the circulation nodes include nodes of the artwork during its circulation process.

[0009] A further technical solution is that the angle of the artwork image is determined according to the matching condition between the angle of the artwork image and the artwork.

[0010] A further technical solution is that the method for determining the recognition accuracy of the circulation node is: Determine the distribution of feature points of the artwork image from the perspective of the artwork image; Determine the number of artwork images corresponding to different feature points according to the distribution of feature points of the artwork images; Based on the number of artwork images corresponding to different feature points, the image recognition coefficients of the different feature points are determined, and the recognition accuracy of the circulation node is determined by the image recognition coefficients of the different feature points.

[0011] A further technical solution is that the recognition accuracy of the circulation node ranges from 0 to 1, wherein when the recognition accuracy of the circulation node is less than a preset accuracy threshold, it is determined that the recognition accuracy of the circulation node does not meet the requirement.

[0012] A further technical solution is that, when a circulation node whose identification matching coefficient does not meet the requirements is found, there is no need to determine the identification matching coefficients of other circulation nodes, and it is directly determined that the accuracy of the traceability result of the artwork does not meet the requirements.

[0013] A further technical solution is to determine whether the accuracy of the traceability result of the artwork meets the requirements, specifically including: Determine the modified matching coefficients of different circulation nodes by multiplying the recognition matching coefficients of different circulation nodes and the recognition accuracy rate; Whether the accuracy of the traceability result of the artwork meets the requirements is determined based on the average values ​​of the corrected matching coefficients of different circulation nodes.

[0014] A further technical solution is that when the average value of the corrected matching coefficients of different circulation nodes is less than a preset matching coefficient threshold, it is determined that the accuracy of the traceability result of the artwork does not meet the requirements.

[0015] In a second aspect, the present invention provides a computer system comprising: a memory and a processor that are communicatively connected, and a computer program stored in the memory and executable on the processor, wherein the processor executes the above-mentioned method for tracing and managing artworks when running the computer program.

[0020] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0021] Whether it is calligraphy and painting, porcelain, pictures or other artworks, there are often multiple image feature points, and these image feature points often do not change in different circulation nodes. Therefore, this application utilizes the consistency of image features in different circulation nodes to achieve traceability management of artworks, thereby ensuring the reliability of traceability management of artworks.

[0022] The specific technical solutions include the following.

[0023] Embodiment 1 To solve the above problem, according to one aspect of the present invention, Figure 1 As shown, a method for tracing the provenance of artworks is provided, which specifically includes: S1 obtains the circulation nodes of the artwork in the traceability process, determines the artwork images of different circulation nodes, and determines the recognition accuracy of different circulation nodes based on the angle of the artwork image and the distribution of feature points of the artwork images at different angles; The feature points are generally the anti-counterfeiting identification parts corresponding to the artwork.

[0024] The recognition accuracy of different feature points is determined based on the ratio of the image clarity of different feature points at different angles to the preset value. Specifically, when the image clarity at different angles is 0.9, 0.95, and 0.93, the recognition accuracy is (0.9+0.95+0.93) / 5=0.566.

[0025] When the recognition accuracy of feature points is distributed as 0.6, 0.7, and 0.8, the recognition accuracy of circulation nodes is 0.7.

[0026] S2: When there is no circulation node whose recognition accuracy rate does not meet the requirement, based on the recognition accuracy rates of different circulation nodes, it is determined that the reliability of the traceability recognition process of the artwork meets the requirement, and then proceed to the next step; When the recognition accuracy of a circulation node is less than 0.6, it is determined to be a circulation node whose recognition accuracy does not meet the requirement.

[0027] The reliability coefficient of the traceability identification process is determined by taking the average value of the recognition accuracy of different circulation nodes. When the reliability coefficient is greater than 0.6, it is determined that the reliability of the traceability identification process of the artwork meets the requirements.

[0028] S3 determines the recognition processing order of different circulation nodes based on the recognition accuracy of the circulation nodes, and performs traceability recognition processing of different circulation nodes in the recognition processing order until the circulation nodes whose recognition matching coefficients do not meet the requirements are determined or all the circulation nodes are determined by matching the artwork images at different angles in the circulation nodes with the preset feature points of the artworks; The recognition matching coefficient is the average value of the image similarity coefficients between the artwork images at different angles and the preset feature points of the artwork. When the recognition matching coefficient is greater than 0.9, it is determined that the recognition matching coefficient of the circulation node meets the requirements.

[0029] S4: When there is no circulation node whose identification matching coefficient does not meet the requirements, the identification matching coefficients and identification accuracy rates of different circulation nodes are used to determine whether the accuracy of the traceability result of the artwork meets the requirements.

[0030] The identification reliability coefficients of different circulation nodes are determined according to the product of the identification matching coefficients and the identification accuracy rates of different circulation nodes. When there is no circulation node with an identification reliability coefficient less than 0.6, it is determined that the accuracy of the traceability result of the artwork meets the requirements.

[0031] Furthermore, the circulation nodes include nodes of artworks during the circulation process.

[0032] Optionally, the angle of the artwork image is determined according to a matching condition between the angle of the artwork image and the artwork.

[0034] Furthermore, the recognition accuracy of the circulation node ranges from 0 to 1, wherein when the recognition accuracy of the circulation node is less than a preset accuracy threshold, it is determined that the recognition accuracy of the circulation node does not meet the requirement.

[0035] Optionally, the image recognition coefficient of the feature point is determined according to the ratio of the number of artwork images corresponding to the feature point to the number of preset images.

[0036] In one embodiment, the method for determining the recognition accuracy of the circulation node is: Determine the distribution of feature points of the artwork image from the perspective of the artwork image; Determine the number of feature points in different artwork images according to the distribution of feature points of the artwork images; Based on the number of feature points in different artwork images, artwork images with a number of feature points greater than a preset number of feature points are determined and used as screening images, and the recognition accuracy of the circulation node is determined based on the number of the screening images.

[0037] Furthermore, when there is a circulation node whose recognition accuracy does not meet the requirement, it is determined that the accuracy of the traceability result of the artwork does not meet the requirement.

[0038] Optionally, the method for determining the recognition accuracy of the circulation node is: S11 determines the distribution of feature points of the artwork image from the perspective of the artwork image; S12 determines the number of artwork images corresponding to different feature points by using the distribution of the feature points, and determines the feature recognition accuracy coefficients of different feature points in combination with the image sizes of the corresponding artwork images; S13 determines preset weight coefficients corresponding to different feature points, and determines the recognition accuracy of the circulation node in combination with the feature recognition accuracy coefficients of the different feature points.

[0039] Furthermore, the preset weight coefficient is determined according to the recognition accuracy of the feature point in the traceability recognition process.

[0040] Optionally, the above step S12 includes the following contents: S121 obtains the number of artwork images. When the number of artwork images is less than the preset number of images, it is determined that the recognition accuracy of the circulation node does not meet the requirement. When the number of artwork images is not less than the preset number of images, the process proceeds to step S122. S122 determines the number of artwork images corresponding to different feature points by using the distribution of feature points. If there are feature points where the number of artwork images does not meet the requirement, the process proceeds to step S123. If there are feature points where the number of artwork images does not meet the requirement, the process proceeds to step S124. S123: When the number of artwork images does not meet the requirement and the number of feature points is greater than the preset number of feature points, it is determined that the recognition accuracy of the circulation node does not meet the requirement; when the number of artwork images does not meet the requirement and the number of feature points is not greater than the preset number of feature points, the process proceeds to step S124; S124 determines the feature recognition accuracy coefficients of different feature points according to the number of artwork images corresponding to different feature points and the image sizes of the corresponding artwork images. When the average value of the feature point recognition accuracy coefficients of different feature points does not meet the requirements, it is determined that the recognition accuracy rate of the circulation node does not meet the requirements. When the average value of the feature point recognition accuracy coefficients of different feature points meets the requirements, it proceeds to step S13.

[0041] Optionally, the above step S13 includes the following contents: S131 determines the corrected recognition accuracy coefficients of different feature points by using the preset weight coefficients and feature recognition accuracy coefficients corresponding to different feature points. When there are feature points whose corrected recognition accuracy coefficients do not meet the requirements, the process proceeds to step S132. When there are no feature points whose corrected recognition accuracy coefficients do not meet the requirements, the process proceeds to step S134. S132: when the number of feature points whose corrected recognition accuracy coefficients do not meet the requirements is greater than the preset number of feature points, it is determined that the recognition accuracy rate of the circulation node does not meet the requirements; when the number of feature points whose corrected recognition accuracy coefficients do not meet the requirements is not greater than the preset number of feature points, the process proceeds to step S133; S133 determines the screening recognition deviation coefficient based on the number of feature points whose corrected recognition accuracy coefficient does not meet the requirement and the corrected recognition accuracy coefficient. When the screening recognition deviation coefficient does not meet the requirement, it is determined that the recognition accuracy rate of the circulation node does not meet the requirement. When the screening recognition deviation coefficient meets the requirement, the process proceeds to step S134. S134 determines preset weight coefficients corresponding to different feature points, and determines the recognition accuracy of the circulation node in combination with the feature recognition accuracy coefficients of the different feature points.
