PanoGS: Gaussian-based Panoptic Segmentation for 3D Open Vocabulary Scene Understanding

2 RayNeo OpenGaussian [45] OpenScene [30] Ours Ground Truth Figure 1. Open Vocabulary 3D Panoptic Scene Understanding. Visualization of open-vocabulary semantic segmentation (yellow boxes) and object query with text toilet (red boxes). Our PanoGS can achieve more accurate segmentation results and generate 3D instance-level results for open-vocabulary text queries, unlike previous methods that generate heatmaps between scene features and text queries.
