Description

Technical Field

[0001] This invention belongs to the field of urban cultural planning technology, and relates to a method, system and storage medium for the overall protection and display of large-scale archaeological sites based on AR. Background Technology

[0002] Major archaeological sites are the core carriers of cultural heritage protection, but most of them face structural conflicts between protection and development with surrounding villages. Strict protection lines for archaeological sites restrict village development, while uncontrolled village expansion, lack of infrastructure, and lagging living conditions continuously damage the site's layout and cultural integrity. Traditional protection methods, such as demolition and relocation, and static isolation, while creating short-term space for the sites, result in a break in historical context, heightened social conflicts, and high economic costs, failing to achieve coordinated development between the sites and villages. Symbiotic theory has been widely applied in urban renewal, heritage protection, and the ecological environment. Domestic and international research explores the symbiotic relationship between heritage and communities from spatial, cultural, and social dimensions, but existing results largely remain at the planning concept and strategy level, lacking a feasible, quantifiable, and iterative technological implementation path. Augmented reality (AR) technology can integrate virtual information with real-world scenes and has been initially applied in archaeological displays and cultural tourism guides, enhancing visualization and interactive experiences; however, current applications are generally fragmented and simplistic.

[0003] In summary, the current technology has four major defects: (1) The protection model of the site and village is rigid: it mainly relies on overall demolition and physical isolation, which destroys the continuity of history, causes people's livelihood and social contradictions, lacks a symbiotic coordination mechanism, and the planning is stuck at the two-dimensional plane level, which cannot dynamically adapt to changes in supply and demand. (2) The cultural display means are single and inefficient: it mainly relies on rammed earth foundations and static exhibitions, the visibility of hidden and semi-hidden sites is extremely poor, the display content is thin and lacks depth, the dissemination of Han culture value is insufficient, and the interactivity and experience are lacking. (3) The planning technology is static and irreversible: it relies on two-dimensional drawings, the three-dimensional expression is insufficient, the plan is difficult to adjust after implementation, and it is easy to cause secondary damage to the site; the public participation channel is lacking, and the opinions of villagers, tourists and other people cannot be effectively transformed into planning basis. (4) The application of AR technology is not systematic: it is only used for single display or tour, and it is not deeply integrated with the symbiotic theory, and cannot solve symbiotic contradictions such as spatial conflict, functional loss, and cultural fragmentation; at the same time, it lacks a complete technical chain of data modeling, virtual and real planning, public feedback and iterative optimization. Summary of the Invention

[0004] The purpose of this invention is to address the technical problems existing in the prior art, such as the prominent contradiction between site protection and village development, static and inefficient cultural display, irreversible planning schemes, insufficient public participation, and fragmented application of AR technology without integration with symbiotic mechanisms. The invention provides a method, system, and storage medium for the holistic protection and display of large-scale archaeological sites based on AR.

[0005] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, this invention discloses a method for the holistic protection and display of large-scale archaeological sites based on AR, comprising: Acquire multi-source data on the major archaeological site and several surrounding villages, and construct a database and current 3D model of the symbiotic system between the archaeological site and villages. Based on the database of the symbiotic system of the major archaeological sites and villages, an AR technology application mechanism based on the theory of symbiosis is constructed. The AR technology application mechanism includes a multi-level AR spatial planning model, a differentiated AR cultural display model for archaeological sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. Based on the existing 3D model and symbiosis theory, an initial planning scheme is generated. Based on the AR technology application mechanism, the initial planning scheme is visualized and integrated with the real scene. Obtain public feedback on the virtual-real integrated visualization display, and iterate and optimize the initial planning scheme based on the feedback to obtain the optimal symbiotic planning scheme.

[0006] Further improvements include: implementing the optimal symbiotic planning scheme after obtaining it, and dynamically monitoring and continuously optimizing the implementation process and operation status through the AR technology application mechanism.

[0007] The process of acquiring multi-source data on the large archaeological site and surrounding villages, and constructing a symbiotic system database and a current 3D model, includes: The multi-source data is standardized and integrated to construct a symbiotic system database that includes symbiotic units, symbiotic environments, symbiotic relationships, and symbiotic conflicts; the multi-source data includes aerial point cloud data, spatial data, cultural resource data, and multi-group demand data. A 3D scene model of the current state of the large archaeological site and village was generated based on aerial point cloud data.

[0008] Constructing the multi-level AR spatial planning model includes: The large archaeological site and several surrounding villages are divided into macro-space, meso-space, and micro-space. An AR public participation reversible planning module is established in the macro space to collect and quantify public opinions in real time. An integrated facility system consisting of AR cultural display facilities, AR navigation signs, and AR interactive nodes will be constructed in the mesoscopic space. An AR ecological landscape rendering and AR spatiotemporal narrative virtual-real overlay module is established in the microscopic space.

[0009] Constructing a differentiated AR cultural display model for the aforementioned site includes: Based on the visibility of the site itself, the sites are divided into visible sites, semi-hidden sites, and hidden sites; For visible archaeological sites, AR augmentation and overlay of information graphics are applied; for semi-hidden archaeological sites, AR outline restoration and virtual structural completion are applied; for hidden archaeological sites, AR full-scene virtual reconstruction and historical spatiotemporal narrative animation rendering are applied. The AR-based cultural tourism industry linkage mechanism includes at least the following: The system includes an AR-based cultural and creative content automatic generation module, an AR-based guided tour route planning module, a cultural tourism experience data collection module, and a village industry information association and push module.

[0010] The AR-based application mechanism integrates the initial planning scheme with the real-world scene for a virtual-real fusion visualization, including: Perform spatial localization and attitude analysis on real-world scenes to obtain spatial matching parameters; Based on the spatial matching parameters, the 3D model and cultural display nodes in the initial planning scheme are aligned with the real scene in spatial coordinates and rendered in real time. In real-world scenarios, the planned spatial layout, cultural narrative content, and facility distribution are displayed through a superposition of virtual and real elements.

[0011] Based on the feedback information, the initial planning scheme is iteratively optimized, including: The unstructured feedback information is structured and transformed into quantitative parameters for planning adjustments. Based on the quantitative parameters, the spatial layout, facility configuration, plant configuration, paving form and cultural display content in the planning scheme are adaptively adjusted to complete the iterative optimization of the scheme.

[0012] Secondly, this invention discloses an AR-based system for the holistic protection and display of large-scale archaeological sites, comprising: The data acquisition module is used to acquire multi-source data from the archaeological site and several surrounding villages, and to construct a database of the symbiotic system between the archaeological site and the villages, as well as a current 3D model. The AR technology application mechanism construction module is used to construct an AR technology application mechanism based on the symbiotic system database of large archaeological sites and villages. The AR technology application mechanism includes a multi-level AR spatial planning model, a site-differentiated AR cultural display model, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. The initial planning and visualization module is used to generate an initial planning scheme based on the existing 3D model and symbiosis theory, and to perform virtual-real fusion visualization of the initial planning scheme with the real scene based on AR technology application mechanism. The solution iteration and optimization module is used to obtain public feedback on the virtual-real integrated visualization display, and to iteratively optimize the initial planning scheme based on the feedback information to obtain the optimal symbiotic planning scheme.

[0013] Thirdly, the present invention discloses an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-mentioned AR-based method for the overall protection and display of large archaeological sites.

[0014] Fourthly, the present invention discloses a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the above-described AR-based method for the overall protection and display of large archaeological sites.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention discloses an AR-based method for the holistic protection and display of large-scale archaeological sites. Compared with traditional static protection, demolition and isolation, and single AR display methods, it has significant advantages. By collecting multi-source data from large-scale archaeological sites and surrounding villages and constructing a symbiotic system database and a current 3D model, it can achieve integrated and digital presentation of information on the space, culture, function, and environment of the sites and villages. This provides comprehensive, accurate, and objective data support for planning decisions, effectively avoiding the bias and errors caused by traditional planning relying on experience-based judgments. Based on the symbiotic system database, it constructs a multi-level AR spatial planning model, a differentiated AR cultural display model for the sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. This forms a systematic and collaborative technical system from multiple dimensions such as spatial layout, cultural interpretation, industrial collaboration, and public education, enabling AR technology to move beyond a single display function and truly serve the symbiotic relationship between large-scale archaeological sites and villages. By balancing needs, the plan addresses core contradictions such as spatial conflicts, functional deficiencies, and cultural fragmentation. It integrates the initial planning scheme with real-world scenarios through virtual and real-world visualization, presenting the planning effect in an intuitive and immersive way. This breaks through the limitations of traditional two-dimensional drawings, significantly improving the comprehensibility and predictability of the planning scheme. Simultaneously, it enables virtual rehearsals without physical construction or disturbance to the site, meeting the requirements of minimal intervention and reversibility for the protection of major archaeological sites. By obtaining public feedback and iteratively optimizing the planning scheme, the needs of villagers, tourists, experts, and other stakeholders can be quantified and integrated into the planning process, forming a dynamic, open, and sustainable planning loop. This ensures that the final optimal symbiotic planning scheme better meets actual usage needs and complies with the requirements for site protection and management. Ultimately, while effectively ensuring the safety and structural integrity of the major archaeological site, it improves the quality of the living environment in surrounding villages, enhances the effectiveness of cultural display and dissemination, and achieves long-term synergistic symbiosis between site protection and village development.

[0016] Furthermore, by standardizing and integrating aerial point cloud data, spatial data, cultural resource data, and multi-group demand data of the major archaeological site and surrounding villages, a symbiotic system database is constructed, encompassing symbiotic units, symbiotic environments, symbiotic relationships, and symbiotic conflicts. Based on the point cloud data, a current 3D scene model is generated, enabling unified, digital, and spatial management of various types of information about the archaeological site and villages. This provides a complete and accurate data foundation for subsequent planning, display, and optimization, avoiding planning deviations caused by fragmented, missing, or inconsistent data. At the same time, it improves the objectivity and comprehensiveness of the planning basis, making the overall protection and display plan more aligned with actual symbiotic needs.

[0017] Furthermore, by adopting a three-tiered spatial division approach (macro, meso, and micro) to construct a multi-level AR spatial planning model, it is possible to achieve deep integration of AR technology and planning design from three levels: overall region, supporting living areas, and spatial node creation. Through AR public participation reversible planning modules, integrated AR facility systems, and AR ecological landscape and spatiotemporal narrative overlay modules, spatial planning becomes more hierarchical, systematic, and feasible. This ensures both the overall control of site protection and the practicality and cultural significance of village micro-spaces, achieving precise symbiosis at the spatial level.

[0018] Furthermore, by classifying sites into visible, semi-hidden, and hidden sites based on their visibility and employing differentiated AR display methods, the problems of displaying invisible or low-visibility sites and transmitting cultural information can be addressed in a targeted manner, enabling sites with different conditions to achieve complete cultural expression. At the same time, by combining AR cultural and creative generation, guided tour planning, data collection, and village industry linkage mechanisms, cultural display can be directly linked with village industrial development, improving the efficiency of cultural dissemination while driving the village economy, and achieving a dual enhancement of cultural symbiosis and industrial symbiosis.

[0019] Furthermore, by structuring unstructured public feedback and transforming it into quantifiable parameters that can be used in planning, and by making adaptive adjustments to spatial layout, facility configuration, plant arrangement, paving patterns, and cultural display content based on these parameters, planning schemes can shift from "experience-driven" to "data-driven," truly transforming public needs into planning basis and significantly improving the rationality and acceptance of the schemes. At the same time, a cyclical and iterative optimization mechanism is formed, allowing the planning to continuously align with the constraints of heritage site protection and the needs of village use, further enhancing the scientific nature and symbiotic balance of the schemes.

[0020] This invention discloses an AR-based holistic protection and display system for large-scale archaeological sites. The system uses a data acquisition module to uniformly collect, standardize, and process multi-source data from the archaeological site and surrounding villages into 3D models, constructing a symbiotic system database and a current 3D model. This enables centralized, structured, and spatial management of information related to the site and village's space, culture, environment, and needs, providing comprehensive, accurate, and reliable data support for subsequent planning and display. It effectively solves the problems of fragmented, inaccurate, and inconsistent traditional planning data. Through an AR technology application mechanism construction module, it can simultaneously establish multi-level AR spatial planning models, differentiated AR cultural display models for the site, AR cultural tourism industry linkage mechanisms, and AR public education and interaction mechanisms based on the symbiotic database. This deeply integrates AR technology with the protection of archaeological sites and the symbiotic needs of villages, forming a complete technical system covering spatial control, cultural interpretation, industrial collaboration, and public education, breaking through the limitations of traditional single-application AR systems. Overcoming the limitations of uniformity and fragmentation, this approach truly resolves symbiotic contradictions such as spatial conflicts, functional deficiencies, and cultural fragmentation through technological means. The initial planning and visualization modules automatically generate initial planning schemes based on existing models and symbiotic strategies, accurately integrating the planning schemes with real-world scenarios in an immersive and intuitive way. This overcomes the shortcomings of traditional two-dimensional drawings, which are often vague and lack predictability, while enabling undisturbed and non-destructive virtual planning simulations, meeting the requirements of minimal intervention and reversibility for the protection of major archaeological sites. The iterative optimization module collects public feedback in real time and transforms it into a basis for planning adjustments, continuously iterating and optimizing the scheme. This makes the planning process more open, dynamic, and aligned with the actual needs of multiple parties, significantly improving the scientific rigor, practicality, and acceptance of the planning scheme. Ultimately, while ensuring the safety and structural integrity of the archaeological site, it achieves an overall improvement in cultural display effectiveness, village living environment, and the quality of symbiotic development.

[0032] Key theoretical explanation: 1. Symbiosis Theory: First proposed in 1879 by German biologist Franz de Bergerac, symbiosis theory refers to the relationship of coexistence between different species linked by a certain substance. It describes the phenomenon of two organisms living closely together in some way. With its development, symbiosis theory has been introduced into various fields such as economics, sociology, urban planning, and architectural design to explain and analyze the interaction and coexistence between different systems or elements. In the fields of architecture, urban design, and planning, Kisho Kurokawa was the first to introduce and explore symbiosis theory in practice. After the 1960s, the disintegration of the Internationalist architectural movement prompted the architectural design community to reflect on and seek new design concepts, giving rise to the theory of metabolism. In 1987, in his book *Symbiosis Thought*, Kisho Kurokawa systematically expounded his architectural philosophy centered on "symbiosis," emphasizing that architecture should possess the capacity for metabolism, like a living organism, maintaining its functional continuity and harmonious coexistence with the environment through continuous self-renewal. This theory is specifically reflected in the symbiotic relationship across multiple dimensions, such as the "balance between specific characteristics and commonalities".

[0033] See Figure 1 This invention discloses an AR-based method for the holistic protection and display of large-scale archaeological sites, comprising: S1. Obtain multi-source data on the large archaeological site and several surrounding villages, and construct a database and current three-dimensional model of the symbiotic system of the large archaeological site and villages. S2, Based on the database of the symbiotic system of the major archaeological sites and villages, an AR technology application mechanism based on the theory of symbiosis is constructed; the AR technology application mechanism includes a multi-level AR spatial planning model, a differentiated AR cultural display model for archaeological sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. S3. Based on the existing 3D model and symbiotic theory, an initial planning scheme is generated. Based on the AR technology application mechanism, the initial planning scheme is visualized and integrated with the real scene. S4. Obtain public feedback on the virtual-real integrated visualization display, and iteratively optimize the initial planning scheme based on the feedback to obtain the optimal symbiotic planning scheme.

[0034] This invention discloses an AR-based method for the holistic protection and display of large-scale archaeological sites. Compared with traditional static protection, demolition and isolation, and single AR display methods, it has significant advantages. By collecting multi-source data from large-scale archaeological sites and surrounding villages and constructing a symbiotic system database and a current 3D model, it can achieve integrated and digital presentation of information on the space, culture, function, and environment of the sites and villages. This provides comprehensive, accurate, and objective data support for planning decisions, effectively avoiding the bias and errors caused by traditional planning relying on experience-based judgments. Based on the symbiotic system database, it constructs a multi-level AR spatial planning model, a differentiated AR cultural display model for the sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. This forms a systematic and collaborative technical system from multiple dimensions such as spatial layout, cultural interpretation, industrial collaboration, and public education, enabling AR technology to move beyond a single display function and truly serve the symbiotic relationship between large-scale archaeological sites and villages. By balancing needs, the plan addresses core contradictions such as spatial conflicts, functional deficiencies, and cultural fragmentation. It integrates the initial planning scheme with real-world scenarios through virtual and real-world visualization, presenting the planning effect in an intuitive and immersive way. This breaks through the limitations of traditional two-dimensional drawings, significantly improving the comprehensibility and predictability of the planning scheme. Simultaneously, it enables virtual rehearsals without physical construction or disturbance to the site, meeting the requirements of minimal intervention and reversibility for the protection of major archaeological sites. By obtaining public feedback and iteratively optimizing the planning scheme, the needs of villagers, tourists, experts, and other stakeholders can be quantified and integrated into the planning process, forming a dynamic, open, and sustainable planning loop. This ensures that the final optimal symbiotic planning scheme better meets actual usage needs and complies with the requirements for site protection and management. Ultimately, while effectively ensuring the safety and structural integrity of the major archaeological site, it improves the quality of the living environment in surrounding villages, enhances the effectiveness of cultural display and dissemination, and achieves long-term synergistic symbiosis between site protection and village development.

[0035] The present invention will be further described below with reference to specific embodiments: Step one involves acquiring multi-source data on the major archaeological site and several surrounding villages to construct a database and a current 3D model of the symbiotic system between the archaeological site and the villages; specifically including: The multi-source data is standardized and integrated to construct a symbiotic system database that includes symbiotic units, symbiotic environments, symbiotic relationships, and symbiotic conflicts; the multi-source data includes aerial point cloud data, spatial data, cultural resource data, and multi-group demand data. A 3D scene model of the current state of the large archaeological site and village was generated based on aerial point cloud data.

[0036] Step two: Based on the aforementioned database of the symbiotic system of large archaeological sites and villages, construct an AR technology application mechanism and symbiotic strategy based on symbiotic theory; the AR technology application mechanism includes a multi-level AR spatial planning model, a differentiated AR cultural display model for archaeological sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism; specifically including: Constructing the multi-level AR spatial planning model includes: The area of ​​the major archaeological site and several surrounding villages is divided into three levels of space: macro-space, meso-space, and micro-space. An AR public participation reversible planning module is established in the macro space to collect and quantify public opinions in real time. An integrated facility system consisting of AR cultural display facilities, AR navigation signs, and AR interactive nodes will be constructed in the mesoscopic space. An AR ecological landscape rendering and AR spatiotemporal narrative virtual-real overlay module is established in the microscopic space.

[0037] By adopting a three-tiered spatial division approach—macro-space, meso-space, and micro-space—a multi-level AR spatial planning model can be constructed. This model enables the deep integration of AR technology and planning design at three levels: the overall region, supporting living areas, and the creation of spatial nodes. Through AR public participation reversible planning modules, an integrated AR facility system, and AR ecological landscape and spatiotemporal narrative overlay modules, spatial planning becomes more hierarchical, systematic, and feasible. This ensures both the overall control of heritage site protection and the practicality and cultural significance of village micro-spaces, achieving precise symbiosis at the spatial level.

[0038] Constructing a differentiated AR cultural display model for the aforementioned site includes: Based on the visibility of the site itself, the sites are divided into visible sites, semi-hidden sites, and hidden sites; AR augmented reality and infographic overlay are applied to visible archaeological sites; AR outline restoration and virtual structural completion are applied to semi-hidden archaeological sites; and AR full-scene virtual reconstruction and historical narrative animation rendering are applied to hidden archaeological sites. Based on the visibility of the sites, they are classified as visible, semi-hidden, and hidden sites, and differentiated AR display methods are adopted. This approach can specifically address the problems of displaying invisible or low-visibility sites and transmitting cultural information, enabling sites with different conditions to achieve complete cultural expression. Simultaneously, by combining AR cultural and creative product generation, guided tour planning, data collection, and village industry linkage mechanisms, cultural display can be directly linked to village industrial development, improving the efficiency of cultural dissemination while driving village economic growth, achieving a dual enhancement of cultural and industrial symbiosis.

[0039] The AR-based cultural tourism industry linkage mechanism includes at least the following: The system includes an AR-based cultural and creative content automatic generation module, an AR-based guided tour route planning module, a cultural tourism experience data collection module, and a village industry information association and push module.

[0040] By standardizing and integrating aerial point cloud data, spatial data, cultural resource data, and multi-group demand data of major archaeological sites and surrounding villages, a symbiotic system database is constructed, encompassing symbiotic units, symbiotic environments, symbiotic relationships, and symbiotic conflicts. Based on point cloud data, a current 3D scene model is generated, enabling unified, digital, and spatial management of various types of information about the archaeological sites and villages. This provides a complete and accurate data foundation for subsequent planning, display, and optimization, avoiding planning deviations caused by fragmented, missing, or inconsistent data. At the same time, it improves the objectivity and comprehensiveness of the planning basis, making the overall protection and display plan more in line with actual symbiotic needs.

[0041] Step 3: Based on the existing 3D model and symbiotic strategy, generate an initial planning scheme, and then use AR technology to visualize and integrate the initial planning scheme with the real-world scene; specifically including: Perform spatial localization and attitude analysis on real-world scenes to obtain spatial matching parameters; Based on the spatial matching parameters, the 3D model and cultural display nodes in the initial planning scheme are aligned with the real scene in spatial coordinates and rendered in real time. In real-world scenarios, the planned spatial layout, cultural narrative content, and facility distribution are displayed through a superposition of virtual and real elements.

[0042] Step four: Obtain public feedback on the virtual-real integrated visualization display, and iteratively optimize the initial planning scheme based on the feedback to obtain the optimal symbiotic planning scheme.

[0043] The unstructured feedback information is structured and transformed into quantitative parameters for planning adjustments. Based on the quantitative parameters, the spatial layout, facility configuration, plant configuration, paving form and cultural display content in the planning scheme are adaptively adjusted to complete the iterative optimization of the scheme.

[0044] Step five involves obtaining and implementing the optimal symbiotic planning scheme, and dynamically monitoring and continuously optimizing the implementation process and operational status through the AR technology application mechanism. Unstructured public feedback is structured and transformed into quantifiable parameters that can be used in the planning. Based on these parameters, adaptive adjustments are made to spatial layout, facility configuration, plant arrangement, paving patterns, and cultural display content. This shifts the planning scheme from "experience-driven" to "data-driven," truly transforming public needs into planning basis and significantly improving the scheme's rationality and acceptance. Simultaneously, a cyclical and iterative optimization mechanism is formed, ensuring the plan continuously aligns with site protection constraints and village usage needs, further enhancing the scheme's scientific rigor and symbiotic balance.

[0045] This invention is illustrated using the Lougetai Village spatial unit within the Han Chang'an City Ruins as a practical example: This invention achieves synergistic coexistence between site protection and village development by constructing a technical process of "digital modeling - AR visualization - public participation and feedback - iterative optimization of the plan," alleviating the symbiotic contradictions at the spatial, functional, and cultural levels, enhancing the effectiveness of cultural display and dissemination, and ensuring the reversibility and minimal intervention of the planning process. Based on the framework of symbiosis theory, this invention addresses the prominent problems of symbiotic contradictions between the protection of large-scale archaeological sites and the development of surrounding villages, as well as the low level of cultural display, proposing a method for applying AR technology in the overall protection and display of large-scale archaeological sites. This embodiment uses the Lougetai Village spatial unit in the Han Chang'an City site area as a practical carrier—this village is located in the northeast of the Han Chang'an City site and contains three core sites (Mingguang Palace Site, Lougetai Site, and Dunhuang Temple Pagoda Site). The Mingguang Palace Site itself is completely invisible, the Lougetai Site has moderate visibility, and the Dunhuang Temple Pagoda Site has high visibility. It also preserves cultural heritage such as ancient Han Dynasty wells, a stone tablet from the thirteenth year of the Chongzhen reign of the Ming Dynasty, and the Dabeifen Tomb, as well as folk customs such as Shehuo performances, Yangko dance teams, dragon and lion dances, etc. All usage and training steps in this embodiment are designed around the resource characteristics and actual needs of the practical carrier. Ultimately, this case verifies the feasibility and effectiveness of the invention, and it can be extended to the protection and display scenarios of other types of large archaeological sites.

[0046] (I) Model and Technology System Construction Step 1: Data Collection and Modeling of the Symbiotic System between Major Archaeological Sites and Villages First, multi-source data on the major archaeological site and surrounding villages were collected through field surveys, drone aerial photography, literature review, and questionnaires. Specifically, a DJI Phantom 4 RTK drone was used to conduct full-coverage aerial photography of the target area, acquiring spatial data such as topography, site distribution, and village building layout. This data was then processed using DJI Terra software to generate 3D point cloud models and current 3D scenes. Literature analysis was used to organize data on the historical evolution of the site, cultural resources (material and intangible), and village value, establishing a cultural resource classification database, as shown in Table 1. Table 1 is the classification table of cultural resources for the Han Chang'an City site. Questionnaires were used to collect needs data from different groups, including villagers, tourists, and planning experts. The questionnaires were divided into versions for professionals, villagers and government staff, and tourists and transient populations, covering needs dimensions such as spatial function, cultural display, and infrastructure.

[0047] The collected multi-source data is standardized and integrated to construct a database of the symbiotic system of large archaeological sites and villages. This database includes core data modules such as symbiotic units (archaeological sites and villages), symbiotic environment (policy, nature, and society), symbiotic relationship (the current state of symbiotic bias), and symbiotic conflict (space, function, and culture).

[0048] Table 1

[0049] Step 2: Construction of AR Technology Application Mechanism and Symbiotic Strategy See Figure 2 Based on a symbiotic system database, this paper constructs an AR technology application mechanism and symbiotic strategy from four dimensions: spatial symbiosis, cultural symbiosis, industrial symbiosis, and consciousness symbiosis. The spatial symbiosis dimension is divided into three levels: city macro, area meso, and spatial unit micro. At the macro level, an AR public participation reversible planning mechanism is constructed, integrating multi-source geographic data through mobile AR applications to collect and quantify public opinions. At the meso level, the AR facility system in the "archaeological site-village" living circle is improved, configuring facilities such as AR cultural and creative supermarkets, AR archaeological site pocket parks, and AR navigation signs. Figure 3 As shown; at the micro level, a spatial unit AR planning model is constructed, including strategies such as ecological landscape creation and AR spatiotemporal narrative; See Figure 4 This AR Han culture sign node showcases a design strategy that combines interactive landscape, ecological rain garden, and AR Han culture spatiotemporal narrative. This landscape feature is not merely a traditional spatial wayfinding facility, but a time link connecting modern visitors with Han Dynasty history.

[0050] (1) AR Han Culture Spatiotemporal Narrative and Time Link: This node innovatively incorporates the concept of "time link" in its design. When visitors enter the scene and use their smart mobile devices to scan the code to trigger the AR function, they feel as if they have crossed the boundaries of time and space and are immersed in the long scroll of Han Dynasty culture. At the AR visual level, the evolution history of Hanfu will be holographically displayed above the sign and in the surrounding space, intuitively showing the origin, form and characteristics of Hanfu, as well as the transformation process of Han elements. At the same time, the system can also combine this spatial node to present other related classic stories and ancient poems of the Han Dynasty to visitors in a three-dimensional visual effect, realizing the leap from "static propaganda" to "immersive interaction" in cultural display.

[0051] (2) Ecological Features and Rain Garden Design: In terms of ecological environment construction, this node breaks through the drawbacks of traditional hard paving that disrupts the surface water cycle, adopting a "soft" permeable concept. The paths around the signs use permeable materials similar to gabion paths, allowing rainwater to naturally infiltrate below the surface, effectively conserving groundwater and highly aligning with the concepts of environmental protection and sustainable development. Simultaneously, abundant native flowerbeds and vegetation are arranged around the scene, collectively constructing a miniature "wetland pool" ecosystem. This design based on the rain garden concept not only enhances the landscape's self-purification and water storage capacity but also plays a positive role in regulating the microclimate of the archaeological site.

[0052] (3) Interactive Landscape and Multi-sensory Experience: This node is not only a visual extension, but also a medium for interaction between people and nature, and between people and technology. While experiencing AR visuals, visitors can also interact with the lighting system of the sign and the surrounding natural environment. For example, as visitors approach or the sky changes, the lights of the sign can automatically adjust the atmosphere, forming an interactive experience that blends the virtual and real worlds, greatly enhancing the attractiveness and enjoyment of the site.

[0053] See Figure 5 This AR Han Dynasty Time Seat node diagram is another core landscape ecological feature in the micro-space AR planning model of this embodiment. Its design deeply integrates Chinese calligraphy art, low-carbon ecological materials and digital interactive technology, providing the public with a composite space that combines rest, viewing and cultural experience.

[0054] (1) Extraction of Han Culture Genes and AR Immersive Display: The cultural core of this time-travel chair extracts the classic "Han Dynasty clerical script" element, especially using representative cultural relics such as the Zhang Qian Stele as the digital gene template. This is also an important trigger point for "time link". When tourists rest on the chair, they can scan a specific area with their mobile devices to display the dynamic trajectory of the evolution of Chinese characters in the real space. The magnificent Han Dynasty clerical script, the ancient Han Dynasty bamboo slips, and poems and songs will be presented to tourists in a three-dimensional way in a floating or surrounding visual form, making the intangible intangible cultural heritage tangible and greatly deepening the dissemination of Han culture in the micro-corners of the archaeological site.

[0055] (2) Recycling of Waste Materials and Ecological Rain Garden: In terms of the selection of materials for the physical construction of the seat, the concept of ecological protection is fully implemented. The seat base adopts a gabion mesh structure combined with discarded wooden planks, which not only has a simple and natural shape that is in harmony with the style of the ruins, but also the gabion mesh structure itself has excellent water permeability, making it an important part of the rain garden system. This "ecological feature" can effectively guide surface runoff and filter and infiltrate rainwater. Combined with the surrounding plant border design, this node and Figure 4 This echoes the concept of wetlands and pools, jointly constructing a vibrant ecological cycle system that avoids the harsh disruption of the soil environment of the archaeological site by human-made facilities.

[0056] (3) Integration of intelligent modules and interactive landscape: In addition, the seating nodes not only have static rest functions, but also integrate solar panels, Bluetooth speakers and intelligent lighting. During the day, they rely on solar energy for power storage, and at night they provide interactive lighting for tourists; the Bluetooth speakers can play Han Dynasty chime bell sound effects or poetry recitations that match the AR visuals. The multi-sensory interactive landscape design transforms the original single resting point into a "life node" that can communicate with tourists in all aspects through sight, hearing and touch.

[0057] An AR mechanism for showcasing Han culture is constructed based on the dimension of cultural symbiosis. Sites are categorized into visible sites (Dunhuang Temple Pagoda Site), semi-hidden sites (Lougetai Site), and hidden sites (Mingguang Palace Site) according to their visibility. Virtual model restoration, replication, or reconstruction schemes are designed for different types of sites, overlaid with animations, images, and other content from intangible cultural resources, such as... Figure 6 As shown, the strategy for coordinated development of cultural tourism and local village industries is constructed from the perspective of industrial symbiosis, and AR-featured products and marketing platforms are developed; the strategy for cultivating public awareness of protection through AR is constructed from the perspective of awareness symbiosis, and AR rural cultural education software and AR heritage protection games are developed.

[0058] Step 3: AR Planning System Development and Debugging An AR planning system was developed using Unity3D as the core development engine, Vuforia SDK as the image recognition tool, and Visual Studio as the programming software. The system includes modules for data import, 3D modeling, AR visualization, public feedback, and scheme iteration. The data import module supports batch import and updates of the symbiotic system database; the 3D modeling module supports planning scheme modeling based on UAV point cloud models, outputting FBX format files; the AR visualization module supports the overlay display of planning schemes through AR glasses (HoloLens2), smartphones, tablets, and other devices; the public feedback module allows users to submit opinions in the form of text, voice, and sketches via QR code scanning; and the scheme iteration module supports parametric adjustments to the 3D model based on feedback.

[0059] The AR planning system was debugged. First, the equipment compatibility, model rendering effect and interaction response speed were tested in the laboratory environment. Then, typical spatial units were selected for on-site debugging to optimize performance indicators such as model loading speed and virtual-real fusion accuracy, so as to ensure that the system can operate stably in the complex environment of the archaeological site.

[0060] (II) Usage Steps (Application and Iteration of Planning Schemes) Step 1: Obtain current status data and load the AR planning system During the planning and implementation phase, drones are used to conduct supplementary aerial photography of the target planning area (such as the two spatial units of Lougetai Village: Site A Mingguang Palace-Lougetai Ruins and Site B Dunhuang Temple Pagoda Ruins) to obtain the latest status data. The data is then imported into the trained AR planning system, i.e. the system developed above, and the corresponding symbiotic strategy module and initial 3D scene model are loaded.

[0061] Step 2: Generate an initial planning scheme and visualize it using AR. Based on the current status model and symbiotic strategy, the AR planning system automatically generates the first version of the planning scheme, including spatial layout, landscape nodes, AR cultural display nodes, etc. Figure 8 As shown, the planning scheme can be visualized at the site using AR devices (AR glasses, smartphones). By wearing AR glasses or scanning QR codes, the public can see the three-dimensional virtual overlay effect of the planning scheme in the real scene, and intuitively experience the spatial form, functional layout and cultural display effect of the planning scheme.

[0062] See Figure 7 The exhibition showcases the overall planning layout of the Lougetai and Mingguang Palace ruins area. This area, representing hidden and semi-hidden ruins, primarily features several earthen mounds. The plan defines mounds numbered 1, 2, and 3, along with their surrounding areas, as the Mingguang Palace ruins area, and the area containing mound number 8, along with the mounds themselves, as the Lougetai ruins area. Through the creation of appropriate landscape nodes and AR (Augmented Reality) ruins restoration technology, a balance between the overall preservation of the ruins and the utilization of space is achieved.

[0063] (1) AR Site Restoration and Visual Reconstruction: Due to the poor visibility of the Mingguang Palace and Lougetai sites, this system introduces high-precision AR site restoration technology. Analogous to the advanced concept of "Digital Restoration of Yuanmingyuan", this solution is no longer limited to the repair of the physical foundation, but uses AR technology to accurately overlay the three-dimensional palace model and architectural components constructed based on archaeological data onto the existing mound. From a specific viewing angle, tourists can see the magnificent Han Dynasty palace complex "rising from the ground" on the originally bare mound through the screen. The imposing rammed earth foundation and double-eaved hip roof can be reproduced across time and space on the original site, which greatly makes up for the shortcoming of the hidden site having no view.

[0064] (2) Functional Zoning and Ecological Landscape Layout: In terms of site functional zoning, the three earthen mounds and pavilion ruins of the Mingguang Palace site are used as core landscape nodes, and archaeological lawns, rest bench areas, and linear paved visitor buffer zones are planned. The design of these areas follows the principle of "minimal intervention". The combination of paving and lawns not only protects the safety of the underground ruins, but also provides public spaces for tourists to stop, observe, and interact. At the same time, isolation flower borders and palace lawns are interspersed around the site, organically integrating them into the overall rainwater ecology and wetland network.

[0065] (3) Analysis of tour routes and visual corridors: From the perspective of tour routes and perspectives, the site's road system adopts a design that combines streamlined and geometrical linearity, guiding visitors to explore the heart of the site in an "exploratory" manner. As visitors walk along the paths, their vision is guided by carefully designed plant screens and perspective views. As they move forward, AR-reconstructed buildings (such as the main hall and side pavilions) from different angles will appear in their field of vision in turn. This visual corridor design with its ever-changing scenery, combined with AR virtual-real fusion technology, allows visitors to fully experience the emotional resonance from "historical ruins" to "the grandeur of the Han Dynasty" while walking, achieving a high degree of unity between spatial tours and cultural exploration.

[0066] Step 3: Public participation, opinion gathering, and plan optimization and iteration The AR planning system's public feedback module collects opinions and suggestions from different groups. Opinion collection points are set up on-site, where villagers, tourists, experts, and others submit real-time feedback via AR devices. This feedback includes suggestions for optimizing the terrain, water features, vegetation, roads, and landscape elements, as shown in Tables 2 and 3. Table 2 summarizes public opinions and adjusts the plan for the Lougetai Mingguang Palace space unit; Table 3 summarizes public opinions and adjusts the plan for the Dunhuang Temple Pagoda space unit. The system structures the collected opinions, converting unstructured opinions (voice, sketches) into quantitative parameters, which are then fed into the plan iteration module.

[0067] Table 2

[0068] Table 3

[0069] Based on the quantified feedback parameters, the first version of the planning scheme is adjusted and optimized to generate a second version, focusing on optimizing aspects such as facility configuration, landscape design, and cultural display that received concentrated public feedback. This process is repeated to continuously collect public opinions and iterate the scheme until the (n+1)th version is generated. This final version serves as the Pareto optimal solution based on public consensus, satisfying the need for a symbiotic balance between heritage site protection and village development.

[0070] Step 4: Implementation and Dynamic Monitoring of the Planning Scheme The final optimized plan will be implemented, with dynamic monitoring conducted using an AR planning system. AR devices will capture real-time construction progress and changes in the site environment, allowing for a comparison between the planned scheme and the actual implementation, enabling timely identification and adjustments to address any discrepancies. After implementation, a long-term dynamic monitoring mechanism will be established using the AR system to regularly collect data on the site's protection status, village development, and public feedback, continuously optimizing the plan to ensure the long-term co-existence and development of the major archaeological site and the village.

[0071] The present invention has the following specific beneficial effects: 1. Resolve the conflict between "archaeological sites and villages" and achieve a win-win situation for protection and development.

[0072] Existing technologies often employ large-scale demolition and relocation models, which can lead to historical discontinuity, high economic costs, and conflicts affecting people's livelihoods. This invention, based on symbiosis theory, utilizes AR technology to construct a multi-dimensional collaborative system between historical sites and villages. It proposes symbiotic strategies across four dimensions: space, culture, industry, and consciousness, effectively mitigating spatial disorder, functional conflicts, and cultural fragmentation between the two. Regarding spatial symbiosis, AR technology enables reversible multi-dimensional dynamic planning, simulating the impact of different planning schemes on historical sites and villages without requiring large-scale modifications to physical spaces. This avoids the disruption of historical continuity caused by demolition and addresses livelihood issues such as lagging infrastructure and scarce public spaces in villages through strategies like optimizing spatial layout and improving living facilities. For example, in Lougetai Village, facilities such as eco-friendly parking spaces and portable toilets planned using AR technology meet the actual needs of villagers without compromising the preservation of the historical site. In terms of industrial symbiosis, AR technology empowers the coordinated development of the cultural tourism industry and local village industries. By developing AR-featured products and building AR marketing platforms, it drives the economic development of villages, increases villagers' income, and achieves the coexistence and prosperity of heritage protection and village development, breaking the previous dilemma of "opposition between protection and development".

[0073] 2. Enrich the forms of cultural display at major archaeological sites and enhance the effectiveness of Han culture dissemination.

[0074] To address the shortcomings of existing large-scale archaeological site displays, such as their limited variety, lack of interactivity, and insufficient depth of content, this invention deeply integrates AR technology with Han culture displays, constructing a diversified and immersive exhibition system. AR technology, through the overlay of virtual and real elements, combines virtual digital information about Han culture (such as historical scene reconstructions and visualizations of intangible cultural heritage) with real-world sites, breaking the limitations of "site reconstruction displays" and "museum exhibitions," allowing visitors to experience the charm of Han culture firsthand. For example, for hidden sites like the Mingguang Palace site, AR technology is used to reconstruct virtual models based on archaeological data, overlaying them with intangible cultural resources such as Han Dynasty poems by Emperor Wu, allowing visitors to intuitively perceive the historical features of the site; for visible sites like the Dunhuang Temple Pagoda, AR technology is used to overlay virtual scenes of high monks reciting the Lotus Sutra, enriching the exhibition content. Meanwhile, the highly interactive expression of AR technology accelerates the two-way flow of culture. Tourists can actively obtain information about Han culture by scanning signs and participating in AR interactive games, and gain a deeper understanding of the architectural art, social customs, and technological achievements of the Han Dynasty. This solves the problems of incomplete display and explanation systems and lack of depth and breadth in the previous system, and effectively enhances the scope of dissemination and public awareness of Han culture.

[0075] 3. Innovate the planning methods for major archaeological sites to improve the scientific nature of the planning and public participation.

[0076] Existing large-scale archaeological site planning often relies on two-dimensional static drawings, which suffers from irreversibility and low public participation. This invention introduces AR technology to construct a reversible planning application mechanism with public participation, revolutionizing planning methods. AR technology supports multi-source data integration and dynamic display, enabling the construction of a virtual-real 3D scene. This allows planners and the public to more intuitively predict the planning implementation effect, avoiding the spatial expression limitations of traditional planar planning. During the planning process, the public can immerse themselves in the planning scheme through AR devices, providing real-time feedback. This feedback, after being organized and analyzed, can be quickly used to optimize and adjust the planning scheme, forming a closed-loop iterative process of "scheme design—AR demonstration—public feedback—scheme modification," ensuring that the planning scheme better aligns with the needs of site protection and the actual demands of the public. This reversible planning model allows for adjustments without demolishing physical buildings, avoiding the resource waste and site damage caused by the irreversibility of traditional planning. Simultaneously, broad public participation breaks the previous "planner- and expert-led" pattern, making villagers, tourists, and other stakeholders participants in the planning process, improving the scientific rigor and operability of the planning scheme, and solving the problem of the disconnect between planning and actual needs.

[0077] 4. Build a systematic AR application system to fully leverage the comprehensive value of technology in the protection of major archaeological sites.

[0078] Existing AR technology applications in the protection of major archaeological sites often focus on single functions, lacking systematicity and coordination. This invention, however, deeply integrates AR technology with symbiosis theory, constructing a systematic application system covering three levels: urban macro, regional meso, and spatial unit micro, encompassing four dimensions: space, culture, industry, and consciousness. At the urban macro level, AR technology enables reversible planning applications through public participation, creating the "Han Chang'an AR Cloud" brand IP and promoting synergy between urban planning and archaeological site protection. At the regional meso level, AR facilities in the "archaeological site-village" living circle are improved, traffic organization is optimized, and the overall service level of the region is enhanced. At the spatial unit micro level, AR technology constructs ecological landscapes and realizes AR spatiotemporal narratives of landscape nodes, promoting micro-level synergy between archaeological sites and villages. This systematic application model not only solves the problem of fragmented single AR application scenarios and the inability to meet multiple needs, but also fully leverages the comprehensive value of AR technology in alleviating symbiotic conflicts, enhancing display effects, and optimizing the planning process through the mutual coordination of strategies across various dimensions, providing a new technical path and solution for the protection of major archaeological sites.

[0079] See Figure 9 The present invention also discloses an AR-based system for the overall protection and display of large-scale archaeological sites, comprising: The data acquisition module is used to acquire multi-source data from the archaeological site and several surrounding villages, and to construct a database of the symbiotic system between the archaeological site and the villages, as well as a current 3D model. The AR technology application mechanism construction module is used to construct an AR technology application mechanism based on the symbiotic system database of the major archaeological sites and villages. The AR technology application mechanism includes a multi-level AR spatial planning model, a differentiated AR cultural display model for archaeological sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. The initial planning and visualization module is used to generate an initial planning scheme based on the existing 3D model and symbiosis theory, and to perform virtual-real fusion visualization of the initial planning scheme with the real scene based on AR technology application mechanism. The solution iteration and optimization module is used to obtain public feedback on the virtual-real integrated visualization display, and to iteratively optimize the initial planning scheme based on the feedback information to obtain the optimal symbiotic planning scheme.

[0080] This invention discloses an AR-based holistic protection and display system for large-scale archaeological sites. The system uses a data acquisition module to uniformly collect, standardize, and process multi-source data from the archaeological site and surrounding villages into 3D models, constructing a symbiotic system database and a current 3D model. This enables centralized, structured, and spatial management of information related to the site and village's space, culture, environment, and needs, providing comprehensive, accurate, and reliable data support for subsequent planning and display. It effectively solves the problems of fragmented, inaccurate, and inconsistent traditional planning data. Through an AR technology application mechanism construction module, it can simultaneously establish multi-level AR spatial planning models, differentiated AR cultural display models for the site, AR cultural tourism industry linkage mechanisms, and AR public education and interaction mechanisms based on the symbiotic database. This deeply integrates AR technology with the protection of archaeological sites and the symbiotic needs of villages, forming a complete technical system covering spatial control, cultural interpretation, industrial collaboration, and public education, breaking through the limitations of traditional single-application AR systems. Overcoming the limitations of uniformity and fragmentation, this approach truly resolves symbiotic contradictions such as spatial conflicts, functional deficiencies, and cultural fragmentation through technological means. The initial planning and visualization modules automatically generate initial planning schemes based on existing models and symbiotic strategies, accurately integrating the planning schemes with real-world scenarios in an immersive and intuitive way. This overcomes the shortcomings of traditional two-dimensional drawings, which are often vague and lack predictability, while enabling undisturbed and non-destructive virtual planning simulations, meeting the requirements of minimal intervention and reversibility for the protection of major archaeological sites. The iterative optimization module collects public feedback in real time and transforms it into a basis for planning adjustments, continuously iterating and optimizing the scheme. This makes the planning process more open, dynamic, and aligned with the actual needs of multiple parties, significantly improving the scientific rigor, practicality, and acceptance of the planning scheme. Ultimately, while ensuring the safety and structural integrity of the archaeological site, it achieves an overall improvement in cultural display effectiveness, village living environment, and the quality of symbiotic development.

[0081] A third objective of this invention is to provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the AR-based method for the overall protection and display of large archaeological sites.

[0082] The AR-based method for the overall protection and display of large-scale archaeological sites includes the following steps: Acquire multi-source data on the major archaeological site and several surrounding villages, and construct a database and current 3D model of the symbiotic system between the archaeological site and villages. Based on the database of the symbiotic system of the major archaeological sites and villages, an AR technology application mechanism based on the theory of symbiosis is constructed. The AR technology application mechanism includes a multi-level AR spatial planning model, a differentiated AR cultural display model for archaeological sites, an AR cultural tourism industry linkage mechanism, and an AR public education and interaction mechanism. Based on the existing 3D model and symbiosis theory, an initial planning scheme is generated. Based on the AR technology application mechanism, the initial planning scheme is visualized and integrated with the real scene. Obtain public feedback on the virtual-real integrated visualization display, and iterate and optimize the initial planning scheme based on the feedback to obtain the optimal symbiotic planning scheme.

[0083] The fourth objective of this invention is to provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the AR-based method for the overall protection and display of large archaeological sites.
