Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional model construction, and in particular to a method for constructing a small and micro three-dimensional model applied to network security and confidentiality equipment. Background Art

[0002] The development of equipment simulators has shown a cross-disciplinary and multi-field development. At present, some equipment simulators have been successfully developed and deployed on a large scale, and have produced positive benefits in equipment teaching, exercises, training and assessment.

[0003] Compared with traditional real-world training systems, simulator systems have the advantages of convenient training, low environmental requirements, low cost, easy large-scale deployment, high safety, low accident frequency, and good training effect. They can fully reproduce the real operation of equipment. Currently, the implementation methods of equipment simulators mainly include three types: full software simulation simulator system, semi-software and semi-hardware simulator system, and full hardware simulator system.

[0004] British researchers first proposed the use of a six-degree-of-freedom (6DOF) 3D simulator. This model primarily constructs a 3D model based on the multi-view and single-view features of the target device input image. While this modeling method is highly efficient, model accuracy is affected by factors such as the dimensionality and number of input views. Based on the multi-view modeling approach, a new method, Structure from Object Motion (SOM), was proposed to reconstruct a point cloud of the 3D model. This method accurately detects feature points in multiple device images, simultaneously derives a parameter matrix by matching multiple image feature points, and constructs the 3D model in real time based on the image sequence. However, this method is limited by the image feature point detection and parameter matrix construction, resulting in excessive computational complexity. For large devices, this method extracts local pixel data from images and extracts image features from multi-view graphic data. Block computation, layered processing, and structural partitioning are used to improve processing parallelism. While suitable for high-level image processing and model construction, it lacks support for modeling accuracy and controllability for smaller devices.

[0005] In order to ensure that the network security defense equipment simulator learning and training system can replace real equipment in teaching, training and practice, its simulator mainly has the following functions: First, it has the ability to simulate the hardware system of the simulated equipment, and realizes the complete simulation of the hardware system of the security and confidentiality equipment in terms of physical appearance, operation panel, communication interface, operating procedures, etc.; Second, it has the ability to simulate the software system of the simulated security and confidentiality equipment, and realizes the complete simulation of the equipment software control system in terms of software control, system configuration, equipment application, assembly process, etc. In response to the current situation of the lack of network security defense simulation training equipment and the difficulty in carrying out large-scale equipment teaching and training, the present invention has carried out research on the technology and method for constructing small and micro three-dimensional precision models of network security and confidentiality equipment, and proposed and designed the technology and method for constructing small and micro three-dimensional precision models of network security and confidentiality equipment. This method is suitable for the design and implementation of the cyberspace security defense equipment simulator learning and training system.

[0006] In the design and development of components for security and confidentiality equipment simulators, directly employing traditional virtual reality technology and 3D modeling methods often results in problems such as low fidelity of device appearance, blurred micro-components, and unclear text display. The design and development of micro-sized 3D models of security and confidentiality equipment components can provide theoretical and methodological support for the research of security and confidentiality equipment simulator learning and training systems. Summary of the Invention

[0088] See also Figure 4 , Figure 4 This is a design diagram of the equipment standardized component library of the SEIM component library described in the present invention.

[0095] The construction technology utilizes full-dimensional geometric feature correlation projection, a key technology in the construction of small and micro-sized 3D precision models of security and confidentiality equipment. This technology is essential for characterizing the imaging features of various installed components, enabling geometric model correlation and matching, and achieving high-resolution projection imaging of the device model. Focusing on the physical shape, skeleton structure, characteristic parameters, and interactive transformations of various physical components of security and confidentiality equipment, full-dimensional geometric feature correlation projection technology primarily performs geometric feature measurement, automatic characteristic parameter correlation, and imaging transformation tracking, key model construction elements. A clearly layered and well-structured 3D skeleton model of the device model is essential for this technology to accurately characterize the geometric shape, physical entity, and manipulation transformation correlation features of security and confidentiality equipment. During the construction of small and micro-sized 3D precision models of security and confidentiality equipment, the device components are often located close to the optical center, and perspective effects in the projected image pattern cannot be ignored. Traditional parallel projection methods cannot be simply applied. Therefore, to effectively represent the 3D geometric features of precision security and confidentiality equipment models, full-dimensional geometric feature projection technology must ensure complete visibility of the device's 3D geometric features, automatically adapt to the security and confidentiality equipment model's application environment, and decompose the multi-dimensional perspective feature parameters of the imaging pattern within the device image. The full-dimensional geometric feature association projection technology adopted in the present invention can realize the accurate description and operation of geometric features, pattern types, and perspective operations such as the equipment skeleton structure, component entities, and projection patterns, thereby ensuring the accuracy, efficiency, and controllability of the equipment's small and micro three-dimensional precision model components.

[0096] High-visibility 3D animation integrated development technology, the visual programming of the security and confidentiality equipment simulator system requires the realization of multiple perspective development tasks, the import and support of various types of equipment 3D precision models, equipment skeleton structures, customizable operation animations, etc., to achieve multi-platform development and deployment. Currently, the more popular ones are mature controls that can be embedded in 3D equipment models and demonstrate 3D model animations, but there are problems such as difficulty in developing visual effects and unfriendly graphical interfaces, which will directly affect the user experience. Inspired by the development of large-scale 3D equipment models, the present invention adopts 3D model interaction and high-visibility 3D animation interactive development technology to achieve the interoperability of security and confidentiality equipment 3D models. High-visibility 3D animation integrated development technology has a powerful cross-platform comprehensive resource integration capability, good support for 3D precision models, and the developed system visualization interface and interactive interface are superior to traditional technical methods. Interactive graphical development environments such as Director, Blenderengine, Virtools, TorqueBuilder, etc. are fully compatible and supportive of high-visibility 3D animation integrated development technology. High-visibility 3D animation integrated development technology supports hierarchical views, project views, and property views. The development structure is clear and inheritable. It also supports vector addition and subtraction, dot multiplication, difference multiplication, and image optimization to meet the development needs of small and micro 3D precision models of security and confidentiality equipment.

[0097] Based on SEIM's standardized component design technology and a standardized component library, complex equipment models are built. This provides basic organizational rules and design procedures for model component development, editing, description, and management, effectively improving the efficiency of SEIM component modeling. The SEIM standardized component library allows for the addition, deletion, and modification of security and confidentiality equipment, and allows for flexible configuration of parameters such as the dimensions, material, color, gloss, and control mode of security and confidentiality equipment components, simplifying the component development process for similar non-standard equipment. The SEIM-based standardized component library for security and confidentiality equipment supports error analysis, problem detection, and compatibility checks, preventing component errors, issues, and incompatibilities from impacting the security and confidentiality equipment model building process. SEIM's standardized component library design pattern can improve the accuracy of model development. The standardized components in the SEIM component library enable flexible device model development under given conditions. Its standardized design and testability are key guarantees for improving the accuracy of complex equipment model development.

[0098] In the cybersecurity and confidentiality equipment simulator learning and training system, guided by and based on small and micro 3D precision model construction technologies and methods, the equipment hardware and software structures are decomposed, classified, and object-by-object, forming static and static geometric feature sets. Based on the model class diagrams, model object diagrams, model component diagrams, and model rule diagrams in the model geometric feature set, a small and micro precision 3D component library is constructed. In the process of modeling the physical appearance, panel structure, interface types, and control modes of the cybersecurity and confidentiality equipment simulator, various precision models of the cybersecurity and confidentiality equipment simulator are generated based on the small and micro precision 3D component library and the precision model state diagrams, activity diagrams, sequence diagrams, and association diagrams in the dynamic precision model diagrams.
