MCGS-SLAM

A Multi-Camera SLAM Framework Using Gaussian Splatting for High-Fidelity Mapping

SLAM System Pipeline

Our method performs real-time SLAM by fusing synchronized inputs from a multi-camera rig into a unified 3D Gaussian map. It first selects keyframes and estimates depth and normal maps for each camera, then jointly optimizes poses and depths via multi-camera bundle adjustment and scale-consistent depth alignment. Refined keyframes are fused into a dense Gaussian map using differentiable rasterization, interleaved with densification and pruning. An optional offline stage further refines camera trajectories and map quality. The system supports RGB inputs, enabling accurate tracking and photorealistic reconstruction.

Analysis of Single-Camera and Multi-Camera System

This experiment on the Waymo Open Dataset (Real World) demonstrates the effectiveness of our Multi-Camera Gaussian Splatting SLAM system. We evaluate the 3D mapping performance using three individual cameras, Front, Front-Left, and Front-Right, and compare these single-camera reconstructions against the Multi-Camera SLAM results.

The comparison highlights that the Multi-Camera SLAM leverages complementary viewpoints, providing more complete and geometrically consistent 3D reconstructions. In contrast, single-camera setups are prone to occlusions and limited fields of view, resulting in incomplete or distorted geometry. Our approach effectively fuses information from all three perspectives, achieving superior scene coverage and depth accuracy. sevdesk erfahrungen

Erfahrungen: Sevdesk

By day three, something clicked. She connected her bank account. Suddenly, sevdesk started automatically sorting her monthly Adobe subscription, her train tickets to Berlin, even that weird Shopify fee. The was 80% right—and the other 20% was easy to fix.

But she pushed through.

But the ? ā€œIt didn’t magically fix everything overnight,ā€ she says. ā€œBut it turned my shoebox of chaos into a clean, digital desk. And that gave me back my weekends.ā€

ā€œJust try it,ā€ she said. ā€œIt’s like a tiny accountant who lives in your computer.ā€

Then, a fellow designer mentioned .

Herr Schmidt called her. ā€œLena? I just downloaded your sevdesk export. This is… complete. For once.ā€ He almost sounded disappointed.

Today, Lena’s Sundays are for brunch and hiking. She opens sevdesk once a week for 20 minutes. The ? The mobile app can be slow when her internet is patchy. And she still doesn’t use the ā€œinventoryā€ feature—overkill for her.


Analysis of Single-Camera and Multi-Camera SLAM (Tracking)

In this section, we benchmark tracking accuracy across eight driving sequences from the Waymo dataset (Real World). MCGS-SLAM achieves the lowest average ATE, significantly outperforming single-camera methods.

We further evaluate tracking on four sequences from the Oxford Spires dataset (Real World). MCGS-SLAM consistently yields the best performance, demonstrating robust trajectory estimation in large-scale outdoor environments.
