CloudAnalyzer: Browser-based LiDAR SLAM map correction and Lanelet2 editing in Rust + WASM
rsasaki0109 · x · 2026-10-02
Developer rsasaki0109 open-sourced CloudAnalyzer, a browser-based LiDAR toolchain for SLAM map correction, point-cloud analysis, and editable Lanelet2 vector-map drafting.
Key points:
- Built with Rust compiled to WebAssembly, running locally on all cores — no install, and data never leaves your machine
- Opens ROS bags or drive poses/scans; supports manual loop closing (demonstrated on the University of Michigan NCLT dataset, aligning the same place seen twice a kilometer apart via ICP), removing passing cars, and comparing against previous maps or ground truth
- Includes a plugin system, CI action, and benchmarks
The author is also experimenting with using agentic AI to generate vector maps.
