The revised version discusses two primary 3D reconstruction methods: vision and LiDAR. Vision relies on triangulation with a limited range, affected by lighting conditions, whereas LiDAR offers broader applicability, particularly in complex environments. The system, integrating LiDAR with a mobile trolley and PYNQ-Z2 platform, employs advanced algorithms for precise point cloud registration and real-time 3D modeling, supporting diverse applications like UAV navigation and cultural heritage preservation.
