Brian Zheng developed advanced perception and deployment features for the WATonomous/wato_monorepo, focusing on robust 3D scene understanding and scalable system integration. He engineered LiDAR-based ground segmentation, multi-camera inference pipelines, and 2D/3D object detection using C++ and Python, leveraging ROS2, Docker, and TensorRT for deployment and runtime efficiency. His work included lifecycle-managed ROS2 nodes, containerized spatial association modules, and ByteTrack-based multi-object tracking, all integrated with automated CI/CD workflows. By emphasizing test coverage, parameter tuning, and streamlined build configurations, Brian improved reliability, maintainability, and deployment reproducibility, enabling faster iteration and more robust perception capabilities across the autonomous vehicle stack.
