Primitive3D

我们提供Primitive3D数据集的两种数据格式，即PLY数据和H5DF数据。PLY数据包含一组。ply文件，每个文件代表原始3d对象的网格。中包含两个额外的信息，来源和标签。ply文件，这是分段标签。H5DF数据代表。为每个对象采样8192点的h5文件。各。h5文件包含以下密钥和数据: 数据: 形状为N X 8192X3的点的坐标。 法线: 形状为N X 8192X3的点的法线。 sem_label: 形状为N X 8192的逐点语义标签。 ins_label: 形状为N X 8192的逐点实例标签。 p_num: 形状为N的对象的原始编号。We provide two data formats for the Primitive3D dataset, namely PLY format and H5DF format. The PLY format consists of a collection of .ply files, where each file represents the mesh of a raw 3D object and contains two additional pieces of information: the source and the segmentation label. The H5DF format comprises H5 files where 8192 points are sampled for each object. Each H5 file contains the following keys and their corresponding data: data: coordinates of points with a shape of N × 8192 × 3; normals: surface normals of the points with a shape of N × 8192 × 3; sem_label: per-point semantic labels with a shape of N × 8192; ins_label: per-point instance labels with a shape of N × 8192; p_num: original object indices with a shape of N.

背景概述

Primitive3D是一个3D对象数据集，提供PLY和H5DF两种格式，分别包含网格标签和点云坐标、法线及语义实例标签。该数据集由新加坡国立大学、苏黎世联邦理工学院和字节跳动于2022年发布。
