东方瑰宝金铜佛像《药师佛》高精度三维数字模型数据集

一、实质性加工1. 三维模型数据定向清洗与优化：定向排查规则：结合《药师佛》核心特征（药壶的弧形轮廓、锡杖的细长结构、手部施无畏印的指节细节），重点排查三类数据问题：药壶壶嘴与壶身衔接处的重叠面、锡杖杖身的冗余顶点、手指关节处的几何信息错误。无效数据删除标准：删除建模误差产生的微小重叠面（面积＜0.01mm²）、锡杖非装饰区域的冗余顶点（间距＜0.02mm），在保留法器细节的前提下，减少 30%-40% 数据量，提升模型加载速度，满足虚拟交互、AR 展示等多场景流畅运行需求。2. 纹理映射精准校准：坐标校准规则：依据《药师佛》金铜材质的光泽特性，按 “法器＞身体＞底座” 优先级校准纹理坐标：药壶表面需确保鎏金纹理沿弧形均匀分布，避免拉伸、扭曲或错位。二、创造性劳动：1. 模型数据精细化处理算法与规则：专业软件处理流程：执行 “叠面消除 - 交叉面修复 - 三角面优化” 三步流程：通过 “曲率分析” 算法识别药壶壶盖与壶身的交叉面并自动修复；采用 “网格简化” 算法，在保证锡杖杖身结构强度的前提下，将三角面数量从原始的 80 万 + 优化至 50 万 +，减少数据冗余。I. Substantive Processing 1. Targeted Cleaning and Optimization of 3D Model Data Targeted Inspection Rules: Combined with the core features of the Bhaisajyaguru Buddha statue (the arc-shaped contour of the medicine pot, the slender structure of the khakkhara, and the knuckle details of the hand in the Abhaya Mudra), three types of data issues are prioritized for inspection: overlapping surfaces at the junction of the medicine pot spout and its body, redundant vertices on the shaft of the khakkhara, and geometric information errors at the finger joints. Invalid Data Deletion Criteria: Delete tiny overlapping surfaces caused by modeling errors (area < 0.01 mm²) and redundant vertices in non-decorative areas of the khakkhara shaft (spacing < 0.02 mm). By reducing the data volume by 30%-40% while preserving the details of the ritual implements, the model loading speed is improved to meet the smooth operation requirements of multiple scenarios such as virtual interaction and AR display. 2. Precise Calibration of Texture Mapping Coordinate Calibration Rules: According to the luster characteristics of the gold-copper material of the Bhaisajyaguru Buddha statue, texture coordinates are calibrated in the priority order of ritual implements > body > base. The gilded texture on the surface of the medicine pot shall be evenly distributed along the arc to avoid stretching, distortion or misalignment. II. Creative Labor 1. Algorithms and Rules for Refined Processing of Model Data Professional Software Processing Workflow: Implement the three-step process of "overlapping surface elimination - cross-surface repair - triangular surface optimization". The "curvature analysis" algorithm is used to identify and automatically repair the cross surfaces between the medicine pot lid and its body. The "mesh simplification" algorithm is adopted to optimize the number of triangular surfaces from the original 800,000+ to 500,000+ while ensuring the structural strength of the khakkhara shaft, thereby reducing data redundancy.
