About this paper
Annika Thomas, Mason Peterson, Jonathan P. How
GaussLite introduces a system that uses natural-language task inputs to dynamically allocate 3D Gaussian Splatting representation capacity during online robotic mapping. This approach achieves higher rendering quality in task-relevant regions, with an average ROI PSNR improvement of +1.25 dB over SplaTAM on Replica and +1.70 dB on Campus datasets, while maintaining real-time performance and enabling efficient multi-agent map fusion.
Key insights
- Dynamically allocating 3DGS representation capacity based on natural language task specifications significantly improves map fidelity in task-relevant regions for real-time robotic mapping.
- By treating 3D scene representations as "task-conditioned cognitive maps," robots can achieve more efficient and purposeful world modeling aligned with their immediate objectives.
- Leveraging per-Gaussian optimization statistics (κ_i) enables efficient, high-quality fusion of task-specialized maps from multiple agents, minimizing communication overhead by exchanging only highly optimized, task-relevant Gaussians.
