Develop an open-vocabulary 3D semantic segmentation framework that recognizes diverse, novel objects beyond predefined category labels.
Designed OV3D to align 3D point features with contextualized textual entity representations derived from vision-language foundation models.
Enriched entity descriptions with broader scene context to facilitate fine-grained cross-modal feature correspondence.
Evaluated open-vocabulary segmentation performance across standard benchmark datasets: ScanNet, Matterport3D, and nuScenes.
Achieved state-of-the-art open-vocabulary semantic segmentation accuracy across ScanNet, Matterport3D, and nuScenes benchmarks.
Demonstrated effective zero-shot recognition of unconstrained object categories by directly matching 3D points to enriched textual concepts.
