SLAM-GS3LAM
See the World in 3D and Know What Everything Is
Robotic platforms navigating complex environments — factory floors, forward operating bases, urban terrain — need to know not just where walls are but what those walls are made of, what is a door versus a barrier, what is equipment versus a person. Pure geometric SLAM gives structure without understanding; pure semantic models need structure to reason about. Combining both in real time on a mobile platform has been the bottleneck.

THE PROBLEM WE SOLVE
Robotic platforms navigating complex environments — factory floors, forward operating bases, urban terrain — need to know not just where walls are but what those walls are made of, what is a door versus a barrier, what is equipment versus a person. Pure geometric SLAM gives structure without understanding; pure semantic models need structure to reason about. Combining both in real time on a mobile platform has been the bottleneck.
Autonomous vehicles and robotic platforms gain spatial understanding that enables task-level reasoning: "navigate to the door marked entrance," "avoid the area classified as unstable terrain," "flag all human-class detections within 10m" — all from one map built on the fly.
WHAT SLAM-GS3LAM DELIVERS
SLAM-GS3LAM (codename: Tsukuyomi) implements GS3LAM (ACM MM 2024), which jointly optimizes camera pose estimation, photorealistic 3D Gaussian reconstruction, and semantic segmentation in a single fused pipeline. RGB, depth, semantic label, and camera intrinsic tensors feed a unified optimization loop; output is a camera pose and an incrementally updated semantic 3DGS map.
CAPABILITIES
- SLAM-GS3LAM (codename: Tsukuyomi) implements GS3LAM (ACM MM 2024), which jointly optimizes camera pose estimation, photorealistic 3D Gaussian reconstruction, and semantic segmentation in a single fused pipeline
- RGB, depth, semantic label, and camera intrinsic tensors feed a unified optimization loop; output is a camera pose and an incrementally updated semantic 3DGS map
- Every Gaussian in the scene carries a class label — queryable, filterable, exportable.
WHY THIS IS HARD
Building SLAM-GS3LAM requires solving multiple coupled problems:
- 01Robotic platforms navigating complex environments — factory floors, forward operating bases, urban terrain — need to know not just where walls are but what those walls are made of, what is a door versus a barrier, what is equipment versus a person
- 02Pure geometric SLAM gives structure without understanding; pure semantic models need structure to reason about
- 03SLAM-GS3LAM (codename: Tsukuyomi) implements GS3LAM (ACM MM 2024), which jointly optimizes camera pose estimation, photorealistic 3D Gaussian reconstruction, and semantic segmentation in a single fused pipeline
- 04RGB, depth, semantic label, and camera intrinsic tensors feed a unified optimization loop; output is a camera pose and an incrementally updated semantic 3DGS map
SLAM-GS3LAM solves these through careful architecture design and rigorous validation.
