QueryGaussian: Scalable and Training-Free Open-Vocabulary 3D Instance Retrieval
QueryGaussian introduces a training-free framework for retrieving 3D instances from massive scenes using natural language prompts, achieving 70% GPU memory reduction and 180x faster inference compared to existing methods. The approach decouples semantic understanding from geometric representation through instance-level queries rather than scene-level embeddings, enabling practical deployment on consumer hardware for city-scale environments with millions of 3D primitives.
