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.

The Catch:

DAZN does not offer a standalone "F1 only" package. You usually need the DAZN Total package, which bundles football (LaLiga, Champions League), MotoGP, and other sports. Prices in Spain range from €29.99 to €44.99 per month depending on promotions and contract length. Many fans share accounts or subscribe only during the European leg of the season.

The Spanish Grand Prix is a staple of the F1 calendar. Whether you are streaming it on your smart TV, tablet, or phone, make sure your internet connection is stable so you don't miss the lights going out.

2026 season

The landscape of Formula 1 streaming in for the is defined by exclusive rights and a shift toward centralized digital platforms. While Spain remains a "DAZN territory," the broader streaming market is evolving, particularly with the 2026 introduction of Apple TV as a primary F1 home in other major markets like the U.S..

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.
