PROFILE
Waterloo Steph
Over four months, Stephen Huang contributed to the WATonomous/wato_monorepo by developing and integrating advanced features for autonomous vehicle software. He implemented traffic sign visualization in the HD Map pipeline, introducing a dedicated C++ class and updating build scripts to enhance situational awareness. Stephen also built a new localization node to preprocess GPS, IMU, and wheel odometry data for EKF-based pose estimation, streamlining system integration with ROS2 and CMake. Additionally, he unified Dockerfiles for the World Modeling component, improving CI reliability and onboarding. His work included supporting Nuscenes OSM maps, updating YAML configurations, and ensuring robust end-to-end map loading.

Oct 1, 2025October 2025: Delivered Nuscenes OSM maps support in the HD Map for WATonomous/wato_monorepo. Implemented configuration updates and C++ loading changes to ingest Nuscenes map data (origins and bounds), and extended docker-compose to mount map data volumes. Completed end-to-end verification of the map loading path with a focused test and committed the changes.

Apr 1, 2025April 2025 (WATonomous/wato_monorepo) focused on enhancing HD Map visualization by delivering Traffic Sign Visualization. A dedicated TrafficSignRegElem class was implemented and integrated into the regulatory element system. Configuration and build scripts were updated to support the new feature, enabling the HD Map pipeline to process and display traffic sign information. This work improves map accuracy, situational awareness, and lays groundwork for future rule-based behaviors.
