Researchers have developed a novel Multi-Scale Gaussian-Language Map (GLMap) designed to improve embodied navigation and reasoning in virtual environments. This system integrates explicit geometry with multi-scale semantic information, including instance and region concepts, and links them to natural language descriptions. The GLMap utilizes 3D Gaussian representations for efficient storage and rendering, and a Gaussian Estimator for rapid map construction from point clouds. Experiments on ObjectNav, InstNav, and SQA tasks demonstrate its effectiveness in enhancing navigation and reasoning capabilities in a zero-shot manner. AI
