Multi‑camera SLAM Multi‑layer optimization LiDAR fusion SLAM‑grade localization

Vision–LiDAR SLAM with Multi‑Layer Optimization

We synchronize multi‑camera rigs with scanning LiDAR and IMUs to capture the environment, then solve localization and mapping through a SLAM‑centric pipeline. Local visual–inertial odometry is reinforced by LiDAR odometry; a multi‑layer optimizer (local → submap → global pose‑graph) fuses loop closures, GPS/INS anchors, and LiDAR ICP constraints to deliver centimeter‑grade, repeatable trajectories for analysis and decision‑making.

On top, our multi‑camera analytics extract assets, markings, and structures, quantify change, and export GIS‑ready layers.

How it works

  1. Sense: synchronized multi‑camera + LiDAR + IMU capture time‑aligned RGB, depth, and point clouds.
  2. Calibrate & time‑sync: intrinsics/extrinsics for all sensors; clock alignment for precise fusion.
  3. Front‑end odometry: visual–inertial odometry (VIO) + LiDAR odometry provide robust motion in all conditions.
  4. Build the graph: keyframes, loop‑closures, LiDAR ICP matches, and GPS/INS priors compose a factor graph.
  5. Multi‑layer optimization: local windows → submap alignment → global pose‑graph for drift‑resistant localization.
  6. Reconstruct & register: fuse frames and scans into dense, colorized 3D meshes and point clouds.
  7. Analyze: multi‑camera perception extracts assets, markings, clearances, and changes across runs.
  8. Deliver: GIS‑ready layers and CAD/BIM exports (GeoPackage, LAS/LAZ, WGS84/OSGB) with reproducible accuracy.

Why SLAM + LiDAR + Multi‑camera

Accurate localization
Multi‑layer optimization stabilizes trajectories with loop closures and GPS anchors.
Geometry in all light
LiDAR complements cameras at night, glare, or texture‑poor scenes.
Consistent structure
Submaps and global alignment reduce drift across long routes.
Rich environmental data
Multi‑camera views improve detection, classification, and change analysis.
Survey‑friendly outputs
Align to control; export to GIS and CAD/BIM with audit trails.
Operational scale
Edge + cloud pipelines process city‑scale datasets and repeat surveys.
