“…It meets the three requirements for the new workflow under the current conservation status and technological background. Compared with the current studies of new digital technology that are applied in the field of cultural resource conservation [23][24][25][26][27][28][29][30][31], this study focuses more on providing framework support for current obstacles. Compared to a specific technology application, the lack of a guiding workflow and framework for sustainable conservation is the core issue that restricts digital recording and utilization.…”

Cultural relics and historical sites serve as carriers of cultural, historical, and artistic information. However, any damage incurred by these cultural relics can result in the loss of information, consequently impacting sustainable conservation and revitalization of the cultural heritage. Han Dynasty stone reliefs are a representative carrier of art and history during the Han Dynasty, an early stage of Chinese history. Due to the influence of materials, carving techniques, and protective measures, the conservation and revitalization of Han Dynasty stone reliefs have been significantly restricted. In this study, a systematic investigation was carried out to study the current situation and existing problems related to the protection of Han Dynasty stone reliefs. Additionally, a case study was conducted using the Wuling Ancestral Hall (Wuliang Shrine) as an example, to explore the integration of 3D digital technology as a new sustainable approach. The results show that natural weathering and conventional techniques have caused irreversible information loss. Thus, adopting a three-dimensional digital perspective is crucial when considering the information preservation and revitalization of Han Dynasty stone reliefs. To achieve this, 3D digital models of representative stone reliefs, tomb chambers, and other sculptures from the Wuliang Ancestral Hall were established. These models provide new paths for accurately recording 3D information and better utilizing cultural heritage. Faced with the challenge of preserving historical heritage and its associated information, a workflow including 3D scanning, data collection and processing, 3D modeling, visualization, and information utilization is proposed. This approach offers new approaches for sustainable conservation and revitalization of Han Dynasty stone reliefs.

“…Suffering from weathering, fires and rotting, a mass of Chinese historical buildings with wooden structural frame has disappeared. The digital archiving was the important measurement for the protection of historical buildings [3,4] and 3D point cloud which can provide the extract spatial geometry of built heritage with a complex shape has been widely used in the documentation of Chinese ancient architectures [5]. However, the captured original point cloud lacked the structured information, such as semantics and hierarchy between parts, which disturbed the usage of point cloud in other application fields [6][7][8].…”

Point cloud semantic segmentation is a key step in the scan-to-HBIM process. In order to reduce the information in the process of DGCNN, this paper proposes a Mix Pooling Dynamic Graph Convolutional Neural Network (MP-DGCNN) for the segmentation of ancient architecture point clouds. The proposed MP-DGCNN differs from DGCNN mainly in two aspects: (1) to more comprehensively characterize the local topological structure of points, the edge features are redefined, and distance and neighboring points are added to the original edge features; (2) based on a Multilayer Perceptron (MLP), an internal feature adjustment mechanism is established, and a learnable mix pooling operator is designed by fusing adaptive pooling, max pooling, average pooling, and aggregation pooling, to learn local graph features from the point cloud topology. To verify the proposed algorithm, experiments are conducted on the Qutan Temple point cloud dataset, and the results show that compared with PointNet, PointNet++, DGCNN, and LDGCNN, the MP-DGCNN segmentation network achieves the highest OA and mIOU, reaching 90.19% and 65.34%, respectively.

“…In recent years, benefiting from the development of digital technology and the abundance of information means, the research on Chinese classical gardens has developed rapidly in terms of digital surveying and mapping, database construction, virtual scene restoration, archiving monitoring, management display, etc. For example, the Zhang Bo team firstly proposes to adopt 3D technology to carry out 3D surveying and mapping of rockery elements in classical gardens [35]; the Guo Daixi team digitally restored some scenic spots in the Old Summer Palace [36]; Wang Shiwei, Hu Jie et al used 3D digital technology to carry out digital mapping and model construction of Qianlong Garden in the Imperial Palace [37]; the Zhang Qingping team collected and integrated data about rockeries and arranged stones at Jiangnan private gardens like Zhan Garden, Ou Garden and Huanxiu Villa [38][39]; based on the "hole" characteristics of rockeries, Yang Chen proposed a method to extract and classify point-cloud cave characteristics [40]; as well as the Qin Ke team carried out long-term research on digitalization of Chinese classical gardens, especially rockery digitalization and quantitative analysis; for example, Wen Ning adopted spatial syntax to analyze the accessibility and connectivity of rockery space in Jingyi Garden [41], Chen Wanyu adopted finite element analysis to statically analyze and simulate the typical cases of rockeries and their skills [42], and Liao Yi, Jia Shizhen et al put forward the information classification of elements of ancient Chinese royal gardens; by taking Jianxinzhai Garden as an example, they classified the involved elements and put forward the path and method for constructing the 3D digital information database against ancient Chinese royal gardens [43][44].…”

Currently, the use of digital technology for the protection and research of cultural heritages has become a trend in this field. These rockeries in Chinese classical gardens have become an important cultural heritage type because of unique shape, ingenious skills and rich connotations. The research difficulty lies in how to objectively describe, quantitatively analyze and evaluate such rockeries in an accurate way. Based on relevant historical information and 3D digital technology, this paper puts forward a quantitative analysis method on the scale, shape and quantity of rockeries in Chinese classical gardens, aiming at exploring the objective description and quantitative analysis path of rockeries at different levels, and taking Wanfang Anhe Rockery in the Old Summer Palace as an example for objective and comprehensive quantitative analysis and verification. Such method is based on quantitative analysis and fine management, and is carried out from four levels, i.e. overall, regional, hierarchical and individual. The above method is used to quantitatively analyze and verify Wanfang Anhe Rockery, wherein the overall scale of such rockery is determined based on the viewing position and viewing line of sight, the regional data show that the precipice area (B) and the drop area (D) are the main areas for rockery construction, Area D is divided into two hierarchies through slices and elevations and Area B is divided into three hierarchies at the hierarchical level, as well as at the individual level, there are 336 rocks in total in this rockery and 275 rocks in Area B, and all the viewing range, overall rockery height, material characteristics and stacking mode have a strong impact on the scale of individual rocks. This method is feasible and effective for quantitative analysis of the scale, shape and quantity of rockeries, which can help understand the basic background of stone rockeries and enhance a refined understanding of stone rockery construction, thereby providing data for preventive protection and informatization management of stone rockeries. The 3D rockery model database based on the overall, regional, hierarchical and individual quantitative analysis and numbering method brings a good application prospect for preventive protection and informatization management of the rockery.
