东方瑰宝金铜佛像《地藏菩萨》高精度三维数字模型数据集
收藏资源简介：
（一）实质性加工 1.数据清洗与优化：针对 OBJ 格式模型，结合地藏菩萨 “袈裟繁复 + 手持双法器” 特征，定向排查并删除袈裟褶皱间隙、锡杖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 34% 数据量，提升模型加载与渲染速度，适配多场景需求。 2.纹理映射调整：依据金铜鎏金材质特性，精确校准纹理坐标，确保袈裟纹饰、锡杖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 1.模型精细化处理：用 Geomagic 软件消除叠面、交叉面，对锡杖节纹、宝珠轮廓进行 “网格优化”，减少三角面数量；调整手持法器的姿态参数，确保符合 “庄严持重” 的造像规范。 2.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袈裟褶皱质感；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。1.
(I) Substantial Processing 1. Data Cleaning and Optimization: For models in OBJ format, targeted inspection and removal of redundant vertices and overlapping faces within the gaps of the Bodhisattva Ksitigarbha’s kasaya folds and the joint between the khakkhara and its hands are carried out based on the features of "intricate kasaya + holding two sacred implements". The data volume is reduced by 34% while retaining details, improving model loading and rendering speed to adapt to multi-scenario requirements. 2. Texture Mapping Adjustment: Precisely calibrate texture coordinates according to the properties of gilt bronze materials, ensuring that the kasaya patterns and the metallic luster of the khakkhara fit the model surface without stretching or misalignment. Adjust the resolution based on application scenarios: retain 4K textures for academic research to present detailed material features, and compress to 2K for mass communication, balancing visual effects and operational performance. (II) Creative Labor 1. Model Refinement Processing: Use Geomagic software to eliminate overlapping and intersecting faces, perform "mesh optimization" on the segment patterns of the khakkhara and the outline of the ornamental pearls, and reduce the number of triangular faces. Adjust the posture parameters of the held sacred implements to conform to the specification of "solemn and dignified" statue creation. 2. Surface and Texture Optimization: Apply an AI adaptive filtering algorithm to process scanning noise, focusing on retaining the warm luster of the gilt material and the texture of the kasaya folds. Manually check for texture gaps and texture deviations, calibrate color values by referencing physical Buddha statues or documented records, and restore the authentic visual effect of gilt bronze materials.
