RTGS: Real-Time 3D Gaussian Splatting SLAM via Multi-Level Redundancy Reduction

A real-time Gaussian Splatting implementation for SLAM systems, building upon the excellent work of MonoGS and Photo-SLAM.

📦 Installation

1. Clone the repository

git clone https://github.com/Nemo0412/MonoRTGS.git
cd MonoRTGS

2. Setup the environment

Environment Note

• environment.yml is for x86 architecture.
• environment_arch.yml is for arm64 architecture (e.g., ONX).

conda env create -f environment.yml
conda activate MonoRTGS

3. Downloading Datasets

The following scripts will automatically download datasets into the ./data folder.

TUM-RGBD Dataset

bash scripts/download_tum.sh

Replica Dataset

bash scripts/download_replica.sh

🚀 Usage

SLAM Runner Script

This project includes convenient scripts to run both the original version (MonoGS) and RTGS version:

Python Script

python3 run_slam.py <version> <config>

Bash Script

./run_slam.sh <version> <config>

Examples

# Run original version
python3 run_slam.py original tum/fr3_office
./run_slam.sh original tum/fr3_office

# Run RTGS version
python3 run_slam.py RTGS tum/fr3_office
./run_slam.sh RTGS tum/fr3_office

Supported Datasets
