Description
PartScan is a large-scale, scene-level dataset for 3D part segmentation produced by the PinPoint3D synthesis pipeline. The dataset, created by Voxel51, addresses the bottleneck of acquiring dense, part-level 3D annotations by generating sparse, real-world-style scans with dense part labels. The dataset page was last updated on June 8, 2026.
Use Cases
Training 3D part segmentation models based on dense part annotations.
Developing embodied AI agents that interact with specific object components based on fine-grained 3D segmentation.
Benchmarking synthetic data pipelines for 3D scene understanding based on the described data-synthesis method.
Strengths
Dataset is generated by the PinPoint3D pipeline, which is designed to produce large-scale, scene-level data.
Contains dense part annotations on sparse, real-world-style scans, addressing a major annotation bottleneck.
Limitations
Description metadata is limited; actual data quality requires manual inspection after download.
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
