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.

And so, the story of Emma, Bitchin' Bubba, Rocky, and the "Braless Forever" movement became a beacon of inspiration for those who believed in living life on their own terms.

Once upon a time, in a small, sun-kissed beach town, there lived a spirited young woman named Emma. Emma was known for her carefree attitude and her advocacy for body positivity and comfort. One of her popular campaigns was "Braless Forever," which encouraged women to embrace their natural selves and reject the constraints of traditional lingerie. bralessforever+bitchinbubba+emma+and+rocky+a

Rocky, played by the charismatic actor who had taken on the role for the film, was immediately drawn to Emma's enthusiasm and Bubba's charm. He was intrigued by their conversation about the "Braless Forever" movement and its significance. And so, the story of Emma, Bitchin' Bubba,

The trio decided to collaborate on a new project – a film that would promote self-acceptance, body positivity, and the importance of following one's dreams. With Bubba's surfing expertise, Emma's advocacy, and Rocky's determination, they set out to create something truly special. One of her popular campaigns was "Braless Forever,"

As the day went on, Emma, Bubba, and Rocky found themselves bonding over their shared values and passions. Rocky, having experienced his fair share of challenges and setbacks, was inspired by Emma's confidence and Bubba's zest for life.

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.
