Description

Technical Field

[0001] The present application relates to the technical field of 3D models, and in particular to a method and device for batch inspection of 3D models, an electronic device and a storage medium. Background Art

[0002] In the field of industrial product design, designers widely rely on 3D models in third-party design software formats. These models, as a bridge between creativity and technology, have greatly enriched the design material library. However, with the diversification of 3D model source channels, the inconsistency of model quality has become an issue that cannot be ignored. Downloading from the Internet, obtaining from suppliers, or sharing through other designers, although these methods are convenient, also bring challenges of uneven model quality. In the application of 3D model library platforms, in order to meet the needs of efficient design and production, batch uploading, storage, and downloading of 3D models have become the norm. However, in this process, the requirements for unified model specifications, compliance with regulations, and consistent quality standards are becoming more and more urgent. Only by ensuring the quality and standardization of the model can errors be reduced in the design stage, design efficiency can be improved, and the subsequent production links can be smoothly carried out. A significant challenge currently faced by 3D model reviewers is that they have to open 3D models one by one for inspection and judgment. This process is not only time-consuming and labor-intensive, but also greatly limits the efficiency of inspection work. Although careful review of each model ensures accuracy, this one-by-one approach undoubtedly becomes a heavy burden when faced with a large-scale model library, and there is an urgent need to find a more efficient and automated solution to deal with it.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0044] First, some nouns involved in this application are analyzed:

[0045] 3D model: A 3D model is a model with three-dimensional data that is constructed in a virtual three-dimensional space using three-dimensional software. It is usually used in fields such as three-dimensional printing, computer graphics, movies, television, video games, and virtual reality. These models define the shape, size, position, and surface characteristics of objects in a three-dimensional coordinate system through a series of geometric elements such as points, lines, and surfaces; 3D models can represent objects or scenes in the real world in great detail, including their shape, texture, color, light and shadow effects, etc. They can be created using various 3D modeling software, such as Blender, 3ds Max, Maya, Cinema 4D, SketchUp, etc. The process of creating a 3D model usually involves steps such as design, modeling, texture mapping, lighting, and rendering.

[0046] Cloud Server: A cloud server is a virtual server based on cloud computing technology that users can access and use through the Internet. Through virtualization technology, cloud servers divide the resources of physical servers (such as CPU, memory, storage, etc.) and allocate them to users on demand. This technology enables users to use computing resources flexibly and efficiently without having to worry about the maintenance and management of physical servers.

[0047] At present, ensuring the compliance of the "normative unification" of 3D models mainly relies on manual inspection and judgment based on the normative documents of the system. This method is not only inefficient, but also easily affected by human factors, resulting in inconsistent judgment results. The consistency of the "geometric quality" requirement standards of 3D models also depends on the professional knowledge and experience of users, which brings a lot of subjectivity. When the professional knowledge of users is limited, it is difficult to accurately judge the quality of the model, thus affecting the overall quality requirements. At the same time, when users conduct "normative unification" and "geometric quality" inspections of 3D models, they usually need to rely on equipment terminals installed with professional software, which limits the flexibility and popularity of the inspection work and restricts the use scenarios. In addition, due to the reliance on manual opening of 3D models one by one for inspection, this method is not only time-consuming and labor-intensive, but also unable to achieve batch inspection, resulting in low inspection efficiency and difficulty in meeting the needs of large-scale 3D model library platform applications.

[0048] Based on this, the embodiments of the present application provide a 3D model batch inspection method and device, electronic device and storage medium, aiming to improve the standardization and uniformity of 3D model batch inspection. The 3D model batch inspection method and device, electronic device and storage medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the 3D model batch inspection method in the embodiments of the present application is described.

[0049] The 3D model batch inspection method provided in the embodiment of the present application relates to the field of 3D model technology. The 3D model batch inspection method provided in the embodiment of the present application can be applied to the terminal, can also be applied to the server side, and can also be software running in the terminal or the server side. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc.; the server side can be configured as an independent physical server, or it can be configured as a server cluster or a distributed system composed of multiple physical servers, and can also be configured as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms; the software can realize the application of the 3D model batch inspection method, etc., but is not limited to the above forms.

[0050] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments, in which tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0051] It should be noted that in each specific implementation of the present application, when it is necessary to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of these data will comply with relevant laws, regulations, and standards. In addition, when the embodiment of the present application needs to obtain the user's sensitive personal information, the user's separate permission or consent will be obtained through a pop-up window or by jumping to a confirmation page. After clearly obtaining the user's separate permission or consent, the necessary user-related data for the normal operation of the embodiment of the present application will be obtained.

[0052] Figure 1 is an optional flow chart of the 3D model batch inspection method provided in the embodiment of the present application. Figure 1The method may include but is not limited to steps S101 to S104.

[0053] Step S101, receiving a plurality of 3D models uploaded by a device, and batch caching the 3D models;

[0054] Step S102, displaying the inspection item configuration page of the 3D model, and obtaining the selected item of the 3D model;

[0055] Step S103, opening the 3D models in sequence, performing batch inspection on the 3D models according to the selected items, and generating batch inspection results of the 3D models;

[0056] Step S104: outputting a batch inspection report of the 3D models based on the results of the batch inspection.

[0057] Steps S101 to S104 shown in the embodiment of the present application perform batch inspection of 3D models uploaded by networked devices according to the inspection item configuration selected by the user, and output a batch inspection report of the 3D models based on the results of the batch inspection, thereby achieving efficient and accurate batch inspection of 3D models.

[0058] Specifically, the cloud server receives multiple 3D model files uploaded from networked devices, such as user computers, mobile devices, or professional modeling software, and caches them in batches to the server's storage medium for subsequent rapid processing and access. Next, the cloud server will display an inspection project configuration interface to the user, which lists all 3D model properties or standards available for inspection. The user can select the items to be inspected on the interface according to actual needs. The user selects the inspection items by clicking, checking, or dragging, and the front end of the page captures these selections in real time and prepares the corresponding inspection logic. The cloud server opens each 3D model file in the cache in a certain order, such as the upload order, file name sorting, or user-specified order. For each model, the cloud server will evaluate each model one by one according to the inspection items selected by the user in step S102 using the corresponding inspection logic or algorithm. During the inspection process, the system records the inspection results of each model, including items that meet the standards and items that do not meet the standards. After completing the batch inspection of all 3D models, the system generates a detailed batch inspection report based on the inspection results. The report should include an overview of the inspection results of each model, specific items that do not meet the standards and their detailed information, possible improvement suggestions, etc. The report can be presented in a variety of forms, such as web pages, PDF documents, Excel tables, etc., depending on user needs and system configuration. Through the above steps, this method realizes the automated batch inspection of multiple 3D models, greatly improving the inspection efficiency and accuracy, and reducing labor costs and error rates. At the same time, this method also provides flexible inspection item configuration and detailed inspection report output functions to meet the diverse needs of different users.

[0059] See also Figure 2 In some embodiments, step S103 may include but is not limited to steps S1031 to S1033:

[0060] Step S1031, opening the 3D models in sequence, and performing batch inspection on the 3D models according to the selected items;

[0061] Step S1032, determining that the 3D model passes the inspection, and generating a first label corresponding to the 3D model;

[0062] Step S1033: determine that the 3D model fails the inspection, and generate a second label corresponding to the 3D model.

[0063] Specifically, refer to Figure 3, according to the inspection items selected by the user in step S102, each 3D model is evaluated one by one. If a 3D model passes all the selected inspection items, the system will generate a first label indicating "passed" or "compliant" for the model, which can be used for subsequent processing, such as automatically placing compliant models into a specific folder, displaying them in different colors or icons in the user interface, etc. If a 3D model fails to pass all the selected inspection items, the system will generate a second label indicating "failed" or "non-compliant" for the model. While generating the second label, the system also records the specific items that failed the inspection and their detailed information for the user to view and correct later. In actual implementation, steps S1031, S1032 and S1033 are completed in a loop or iteration manner, that is, these three sub-steps are repeated for each 3D model. The generation and recording of the label is associated with the unique identifier of the model so that the inspection results and label information of each model can be accurately identified and accessed later.

[0064] In some embodiments, step S1032 further includes:

[0065] generating a first label corresponding to the 3D model, and storing the first label in a historical batch inspection table;

[0066] The historical batch inspection table is used for quickly outputting batch inspection results of 3D models that are subsequently uploaded repeatedly.

[0067] Specifically, after generating the first label, the system stores the label and related information, such as model ID and inspection time, in a special historical batch inspection table. This table is a database table or similar structured data storage, which is used to record all 3D models that have undergone batch inspections and their results. The historical batch inspection table contains multiple fields, such as model ID, inspection time, inspection results, inspection item details, etc. Through these fields, the system can easily query and manage historical inspection results. Storing the first label in the historical batch inspection table is to improve the efficiency of subsequent processing, especially when the same 3D model is uploaded repeatedly, the system can first query the historical batch inspection table to quickly determine whether the model has passed the inspection before. If so, the previous results can be directly output without re-inspection, thereby saving time and computing resources.

[0068] In some embodiments, the inspection items include a standardized unified compliance inspection, and the standardized unified compliance inspection includes a file name specification inspection, a sketch specification inspection, an assembly specification inspection, an entity specification inspection, and a feature specification inspection;

[0069] The file name standard check includes reading the file name string of the 3D model, matching and checking the file name string with a preset string, and obtaining a file name standard check result;

[0070] The sketch specification check includes outputting a sketch specification check result according to an under-constrained state and an over-constrained state existing in the sketch of the 3D model;

[0071] The assembly specification check includes outputting the assembly specification check result based on the under-constraint state and interference state of the assembly parts of the 3D model;

[0072] The entity specification check includes outputting entity specification check results according to external references, suppressed features and compressed features of the entity parts of the 3D model;

[0073] The feature specification check includes performing a modeling feature production test on the 3D model, and outputting a feature specification check result based on a result of the modeling feature production test.

[0074] Specifically, by conducting a detailed and unified compliance check on the 3D model, the standardization of the 3D model can be evaluated more comprehensively and accurately, providing strong support for subsequent model optimization and manufacturing work. In the process of unified compliance check, the file name string of the 3D model is first read, and it is matched and checked with the preset string rules or patterns, so as to output the file name standard check results, including whether it has passed the check, which rules are not met, etc. This ensures that the file name complies with the naming standards of the organization or project, which facilitates the identification, management and traceability of files. Then analyze the sketch elements in the 3D model to check whether there are under-constrained (i.e., incompletely defined geometric relationships) and over-constrained (i.e., redundant and conflicting geometric relationships) states, so as to output the sketch standard check results, including which sketches have under-constrained or over-constrained problems, to ensure that the sketch design is accurate and unambiguous, and can correctly guide subsequent modeling work. Secondly, check the constraint relationship between the assembly parts of the 3D model, identify whether there is under-constraint (i.e., insufficient connection between parts) and interference (i.e., parts overlap or conflict in space), and output the assembly specification check results, including which assembly parts have under-constraint or interference problems, so as to ensure that the assembly design is reasonable and collision-free, and can correctly simulate the actual assembly process. Then analyze the external references (such as links to other files), suppressed features (i.e., hidden or disabled design elements) and compressed features (i.e., compressed or simplified design elements) of the entity parts in the 3D model, and output the entity specification check results, including which entity parts have external reference problems, suppressed or compressed feature problems, etc., so as to ensure that the design of the entity parts is complete and without omissions, and all design elements are in the correct state. Finally, the 3D model is subjected to modeling feature production testing, that is, simulating the feature processing process in the actual production process, checking whether there are features that cannot be produced or do not meet the production specifications, and outputting the feature specification check results, including which modeling features have production problems or do not meet the specifications, to ensure that the design features in the model can be implemented in actual production and meet production standards and requirements. After the compliance check is completed, the compliance check results are output, including a summary of the check results in various aspects such as file name, sketch, assembly, entity and feature.

[0075] In some embodiments, the inspection items include geometric quality inspection, and the geometric quality inspection includes tiny element inspection, discontinuity inspection, hollow facet inspection, isolated element inspection, and defect or redundant entity inspection.

[0076] The tiny element inspection includes calculating the tiny curve length, tiny element area and tiny element volume of the 3D model, comparing the tiny curve length, the tiny element area and the tiny element volume with the preset curve length, the preset element area and the preset element volume, and outputting the tiny element inspection result;

[0077] The discontinuity check includes outputting a discontinuity check result based on curve continuity and surface continuity of the 3D model;

[0078] The hollow patch inspection includes identifying a closed space patch group of the 3D model, and outputting a hollow patch inspection result based on the closed space patch group;

[0079] The isolated element inspection includes outputting isolated element inspection results according to the number of isolated edges and isolated facets of the 3D model;

[0080] The defect or redundant entity inspection includes outputting defect or redundant entity inspection results based on open shells and overlapping shells existing in the 3D model.

[0081] Specifically, by performing a detailed geometric quality check on the 3D model, the geometric quality of the 3D model can be evaluated more accurately and comprehensively, providing strong support for the optimization and subsequent application of the model. First. By calculating the tiny curve length, tiny element area and tiny element volume in the 3D model, and comparing these values ​​with the preset thresholds (preset curve length, preset element area, preset element volume), the elements that may cause problems in actual manufacturing or rendering due to their small size are identified, thereby outputting the tiny element inspection results, including which elements are identified as tiny elements, ensuring that all elements in the model are large enough to avoid problems in subsequent processes, such as precision limitations during printing or loss of details during rendering. Next, the curve continuity and surface continuity of the 3D model are analyzed to check whether there are discontinuous points, lines or surfaces, and the discontinuity inspection results are output, including which parts have discontinuity problems, to ensure that the geometry of the model is smooth and continuous, which is crucial for many applications (such as CAD / CAM, simulation). Next, identify the closed space face groups in the 3D model, that is, the face sets that are not filled with solid materials, and output the hollow face inspection results, including which face groups are identified as hollow, to ensure that there are no unnecessary hollow parts in the model, which may cause problems during the manufacturing process, such as material waste or insufficient structural strength. Then count the number of isolated edges and isolated faces in the 3D model. These elements are not connected to other parts of the model. Output the isolated element inspection results, including the number and position of isolated edges and isolated faces, identify and remove or correct isolated elements in the model, which may be errors or unnecessary remnants in the modeling process. Finally, check whether there are open shells (i.e., entities that are not completely closed) and overlapping shells (i.e., two or more entities overlap in space) in the 3D model, and output defect or redundant entity inspection results, including which entities have open or overlapping problems, to ensure that the geometric structure of the model is complete and non-redundant, which is necessary for subsequent manufacturing and simulation processes.
