Gaussian SLAM

Overview

Gaussian SLAM is a cutting-edge method for reconstructing photorealistic 3D scenes from RGBD data streams. As the first neural RGBD SLAM approach capable of delivering real-world scene reconstruction with high visual fidelity, it represents a significant advancement in the field. By utilizing 3D Gaussians as the core element for scene representation, Gaussian SLAM effectively addresses the limitations inherent in traditional methods. Our research reveals that conventional 3D Gaussians face challenges when applied to monocular settings: they struggle to capture precise geometric information and are difficult to optimize sequentially under single-view supervision.

To overcome these obstacles, we have extended traditional 3D Gaussians to encode geometric data more effectively. This innovation is paired with a novel scene representation framework and an optimized method for its growth and refinement. As a result, Gaussian SLAM emerges as a robust system capable of reconstructing and rendering real-world datasets efficiently while maintaining high performance.

Our experiments demonstrate the effectiveness of this approach across various synthetic and real-world datasets, consistently outperforming existing state-of-the-art SLAM methods. Furthermore, we showcase that the generated 3D scene representation can be rendered in real-time using Gaussian splatting techniques, making it highly suitable for practical applications.
