OmniObject3D Dataset

OmniObject3D is a large vocabulary 3D object dataset with massive high-quality real-scanned 3D objects. OmniObject3D has several appealing properties:

1) Large Vocabulary: It comprises 6,000 scanned objects in 190 daily categories, sharing common classes with popular 2D datasets (e.g., ImageNet and LVIS), benefiting the pursuit of generalizable 3D representations.

2) Rich Annotations: Each 3D object is captured with both 2D and 3D sensors, providing textured meshes, point clouds, multiview rendered images, and multiple real-captured videos.

3) Realistic Scans: The professional scanners support highquality object scans with precise shapes and realistic appearances.

OmniObject3D 是一个包含大量高质量真实扫描3D对象的庞大词汇量3D对象数据集。OmniObject3D 拥有多项引人注目的特性：

1) 庞大的词汇量：该数据集包含6,000个扫描对象，涵盖190个日常类别，与流行的2D数据集（例如 ImageNet 和 LVIS）共享常见类别，有利于追求可泛化的3D表示。

2) 丰富的标注：每个3D对象均由2D和3D传感器捕捉，提供纹理网格、点云、多视角渲染图像以及多个真实捕获的视频。

3) 真实扫描：专业的扫描仪支持高质量的物体扫描，具有精确的形状和逼真的外观。
