东方瑰宝金铜佛像《观音菩萨》高精度三维数字模型数据集

（一）实质性加工
数据清洗与优化：针对 OBJ 格式模型，结合观音 “衣纹繁复 + 手持法器” 特征，定向排查并删除衣纹间隙、净瓶与手部衔接处的冗余顶点及重叠面，在保留细节的前提下减少 33% 数据量，提升模型加载与渲染速度，适配多场景需求。
纹理映射调整：依据金铜鎏金材质特性，精确校准纹理坐标，确保衣纹纹饰、璎珞金属光泽贴合模型表面，避免拉伸、错位；按应用场景调整分辨率：学术研究保留 4K 纹理呈现材质细节，大众传播压缩至 2K，平衡视觉效果与运行性能。
（二）创造性劳动
模型精细化处理：用 Geomagic 软件消除叠面、交叉面，对净瓶瓶嘴、璎珞链节进行 “网格优化”，减少三角面数量；调整观音手持法器的姿态参数，确保符合 “优雅慈悲” 的造像规范。
表面与纹理优化：运用 AI 自适应滤波算法处理扫描噪点，重点保留鎏金材质的温润光泽与衣纹质感；人工校验纹饰断层、纹理偏差，参考实体佛像（或文献记载）校准色值，还原金铜材质真实视觉效果。

(I) Substantive Processing
1. Data Cleaning and Optimization: For OBJ-format 3D models, targeted identification and removal of redundant vertices and overlapping faces in the gaps between garment folds and at the junction between Guanyin's holy water vase and hands were conducted, based on the characteristics of Guanyin with "intricate garment patterns and holding a ritual implement". While preserving detailed features, the data volume was reduced by 33%, which improved model loading and rendering speeds and enabled adaptation to multi-scenario requirements.
2. Texture Mapping Adjustment: According to the material properties of gilded bronze, texture coordinates were precisely calibrated to ensure that garment patterns and the metallic luster of jeweled necklaces fit tightly to the model surface, eliminating stretching and misalignment. Resolution was adjusted based on application scenarios: 4K textures were retained for academic research to showcase detailed material features, while they were compressed to 2K for mass communication to balance visual effects and operational performance.
(II) Creative Labor
1. Model Refinement Processing: Geomagic software was utilized to eliminate overlapping and intersecting faces, and "mesh optimization" was performed on the spout of the holy water vase and the links of the jeweled necklaces to reduce the number of triangular faces. Pose parameters of Guanyin's held ritual implement were adjusted to comply with the iconographic specifications of "elegance and compassion".
2. Surface and Texture Optimization: AI adaptive filtering algorithms were applied to remove scanning noise, with priority given to preserving the warm luster of the gilded material and the texture of garment folds. Manual verification was carried out for pattern faults and texture deviations, and color values were calibrated by referencing physical Buddha statues (or documented records) to restore the authentic visual effect of the bronze-gilded material.
