Research Paper
Core Innovation
This paper presents GPS-SLAM, which uniquely integrates colorized Signed Distance Fields with 3D Gaussians to enhance 3D scene reconstruction speed and quality. It reduces computational complexity by halving the number of Gaussians and cutting optimization iterations by 75%, achieving over 150 fps without sacrificing fidelity. This approach offers a significant speedup compared to prior Gaussian-based SLAM methods while maintaining comparable reconstruction accuracy.

Research Paper Overview
Gaussian-Plus-SDF SLAM: High-fidelity 3D Reconstruction at 150+ fps
Summary
This paper introduces GPS-SLAM, a real-time 3D reconstruction system that combines a colorized Signed Distance Field (SDF) with 3D Gaussians to achieve high-fidelity RGB-D scene modeling at over 150 fps. It drastically reduces computational load by halving Gaussian counts and cutting optimization iterations by 75%, enabling an order-of-magnitude speedup over existing Gaussian-based SLAM methods while maintaining comparable reconstruction quality.
