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.

As the virtual captain lifted the trophy to the roar of a digitized crowd, Marco realized why he still played this version. In the world of modern gaming, where things are often "live services," this tiny .rar file was a reminder that some classics are kept alive not by big studios, but by the fans who refuse to let the ceremony end.

Marco, a longtime fan of Pro Evolution Soccer 2013 , clicked "Extract Here." He wasn’t looking for updated rosters or HD grass; he wanted the soul of the game back—the moment where the sweat and tactical grit of a 38-game season culminated in silver trophies and raining confetti.

The digital crowd held its breath as the progress bar for finally hit 100%. For a game released over a decade ago, finding a working mod that added authentic trophy celebrations and post-match festivities was like discovering a relic. As the virtual captain lifted the trophy to

The match was a tense 1-0 victory. When the final whistle blew, the mod came to life. Instead of the generic, repetitive cuts, the screen faded into a cinematic masterpiece. Players fell to their knees, the "Champions" banner was hoisted by stadium staff, and his captain stepped onto a custom-built podium. The digital crowd held its breath as the

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.
