东方瑰宝金铜佛像《四大天王东方持国天王》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，结合持国天王 “手持琵琶 + 复杂铠甲” 特征，定向排查并删除扫描产生的冗余顶点（如铠甲鳞片间隙、琵琶弦槽的无效数据）、重叠面（如琵琶与手部衔接处），在保留细节的前提下减少 32% 数据量，提升模型加载与渲染速度，满足虚拟交互、AR 展示等多场景流畅运行需求。
纹理映射调整：依据金铜鎏金材质特性，精确校准纹理坐标，确保铠甲鎏金纹理、琵琶木质纹理贴合模型表面，避免出现拉伸、错位；按应用场景调整分辨率：学术研究场景保留 4K 高分辨率纹理以呈现材质颗粒细节，大众传播场景压缩至 2K 分辨率，平衡视觉效果与运行性能。
（二）创造性劳动
模型精细化处理：使用 Geomagic 软件消除叠面、交叉面，对琵琶弦轴、铠甲兽首等精细结构进行 “网格优化”，在保证形态精准的前提下减少三角面数量。
表面与纹理优化：运用 AI 自适应高斯滤波算法处理扫描噪点，重点保留鎏金材质的光泽反射细节（如铠甲凸起处的高光）、琵琶木质的纹理质感，避免算法过度平滑导致的质感丢失。

(1) Substantial Processing
Data Cleaning and Optimization: For OBJ format 3D models, based on the features of "holding a pipa + wearing complex armor" of Chiguo Heavenly King, redundant vertices (e.g., invalid data in armor scale gaps and pipa string grooves) and overlapping faces (e.g., at the connection between the pipa and the hand) generated during scanning are targetedly identified and removed. The data volume is reduced by 32% while preserving details, which improves model loading and rendering speed and meets the smooth operation requirements of multiple scenarios such as virtual interaction and AR display.

Texture Mapping Adjustment: Accurately calibrate texture coordinates according to the characteristics of gold-copper gilded materials to ensure that the gilded texture of the armor and the wood texture of the pipa fit the model surface and avoid stretching and misalignment. Adjust the resolution according to the application scenario: retain 4K high-resolution textures for academic research scenarios to present material particle details; compress to 2K resolution for mass communication scenarios to balance visual effects and operating performance.

(2) Creative Labor
Model Refinement Processing: Use Geomagic software to eliminate overlapping and intersecting faces, and perform "mesh optimization" on fine structures such as the pipa's tuning pegs and the armor's beast heads, reducing the number of triangular faces while ensuring accurate morphology.

Surface and Texture Optimization: Use AI adaptive Gaussian filtering algorithm to process scanning noise, focusing on retaining the specular reflection details of gilded materials (such as highlights on the raised parts of the armor) and the texture quality of the pipa's wood, to avoid texture loss caused by excessive smoothing of the algorithm.
