Dataset Highlights
A large-scale real scanned 3D object dataset that provides a solid foundation for 3D vision research.
High-Quality Mesh Models
Each 3D object comes with a detailed triangular mesh model, featuring high polygon density and real geometric details, ready for rendering and analysis.
Real 3D Scans
All objects are captured using professional 3D scanning equipment, not synthetically generated, ensuring the authenticity and accuracy of geometric shapes and surface textures.
190 Categories of Everyday Items
Covers 190 categories of everyday items including furniture, food, toys, tools, electronics, etc., with a wide distribution of categories that closely resemble real-world scenarios.
Multi-Angle Renderings
Provides multi-angle rendered images for each object, supporting research tasks such as Novel View Synthesis and multi-view 3D reconstruction.
Texture Maps
Includes high-resolution texture maps that realistically reproduce the surface materials, colors, and details of objects, suitable for realistic rendering and visual research.
Point Cloud Data
Provides high-density point cloud data sampled from mesh models, directly usable for point cloud classification, segmentation, and 3D feature learning algorithms.
Applicable Scenarios
From academic research to industrial applications, covering core tasks in 3D vision.
3D Reconstruction
Utilize multi-view images and real geometric data to train and evaluate reconstruction algorithms such as NeRF and 3D Gaussian Splatting.
Object Classification
Perform 3D object classification based on point clouds or mesh models, evaluating the performance of classification networks like PointNet and DGCNN.
3D Generation
Provide high-quality training data for 3D diffusion models and generative adversarial networks, researching the generation of 3D objects from text/images.
Novel View Synthesis
Train view synthesis models using multi-angle rendered images to generate realistic images from sparse views at any angle.
