This dataset is constructed based on point cloud data processing technologies, complying with cultural relic digital collection specifications. Its core rules and algorithms are as follows: First, raw data is collected via laser scanning combined with multispectral imaging technologies, which ensures that both the spatial structure and color information of Thangkas are obtained; Second, the statistical filtering algorithm is applied during the point cloud processing stage to remove environmental noise and retain valid data points; Third, multi-view point cloud registration is completed using the Iterative Closest Point (ICP) algorithm to achieve overall model stitching; Fourth, the Poisson surface reconstruction algorithm is adopted in the surface reconstruction phase, which ensures the model's smoothness while fully preserving detailed features such as lines and textures of Thangkas; Fifth, the color correction algorithm is utilized in the color mapping stage to restore the original hues of Thangka pigments. The dataset supports mainstream 3D model formats including .obj and .ply, allows secondary editing via software such as MeshLab and Blender, and adopts a unified world coordinate system to guarantee data universality and reusability.
