Building a Real-to-Sim pipeline for autonomous agricultural robotics — from raw LiDAR/Camera/IMU sensor data to simulation-ready Digital Twins in NVIDIA Isaac Sim from a single sensor pass.

FAST-LIVO2 SLAM → 3D Gaussian Splatting (3DGRUT) → USDZ / NuRec → NVIDIA Isaac Sim + PhysX

→ Research topic overview

Automated generation of high-fidelity Digital Twin simulation environments for autonomous agricultural robots.

• Multimodal sensor calibration: LiDAR/Camera/IMU, targetless, PTP/PPS synchronisation (Ouster, Allied Vision, Microstrain)
• FAST-LIVO2 LiDAR-Inertial-Visual SLAM for accurate pose estimation and point cloud generation
• Neural rendering via 3DGRUT with USDZ export and PhysX integration into NVIDIA Isaac Sim
• PSNR ≥ 27 dB reconstruction quality, further optimised via LVBA-based framework
• Dual simulator integration: ROS2-native Gazebo sensor plugin + NVIDIA Isaac Sim via NuRec

Open-source benchtop visual inspection system fusing laser line profiling and hyperspectral imaging to generate synthetic 3D plant training models for ML applications in precision agriculture.

• Dual Gocator 2350A laser line profilers + Resonon Pika L hyperspectral camera (281 channels, 400–1000 nm)
• 2.1 nm spectral resolution and 0.019 mm Z-resolution — exceeds state of the art at the time.
• PSO-based pixel-accurate sensor alignment; Poisson surface reconstruction; .ply / .obj export
• Implemented in Python with ROS sensor drivers and Open3D
