3Shape FDI 16 Meshes from Intraoral Scans

Version update 2024-02-16: Changed test data to also be from european scans.

The FDI 16 tooth mesh dataset including original meshes and exact data used in the original VF-Net paper. All scans are fully anonymized and donated by 3Shape.

The data contains 4844/1465/1423 meshes and point clouds for train/val/test respectively for deep/machine learning. All data stems from clinics based in Europe. The scans were collected using TRIOS scanners, and primarily the TRIOS 3 model. The data serves as a new and highly relevant use case for computer algorithms for 3D objects.

Each scan contain:
"_mesh.ply" suffix file: A PLY file of the original segmented tooth mesh"_point_cloud.ply": The vertices and facet midpoints of the mesh as a point cloud"_curvature_edgedistance.dat": A binary file including first the curvature of each point in the "_point_cloud.ply" and subsequently the djikstra distance to nearest edge vertex.

2024年2月16日版本更新：测试数据亦调整为源自欧洲的扫描数据。

FDI 16齿网格数据集，包含原始网格及原版VF-Net论文中所使用的精准数据。所有扫描数据均已完成匿名化处理，由3Shape公司捐赠提供。

该数据集包含4844、1465、1423个网格与点云数据，分别用于深度学习/机器学习的训练、验证与测试环节。所有数据均来自欧洲的临床机构。扫描数据采用TRIOS扫描仪采集，其中以TRIOS 3型号为主。本数据集可为三维物体计算机算法提供全新且极具相关性的应用场景。

每份扫描数据包含以下文件：
1. 带"_mesh.ply"后缀的文件：原始分割牙齿网格的PLY格式文件
2. "_point_cloud.ply"：以点云形式存储的网格顶点与面片中点数据
3. "_curvature_edgedistance.dat"：二进制文件，依次存储"_point_cloud.ply"中每个点的曲率，以及该点到最近边缘顶点的迪杰斯特拉（Dijkstra）距离。
