Shaping digital twins: exploring uav and web-based 3d modeling technologies for sustainable building simulation

The integration of Uncrewed Aerial Vehicles (UAVs) and web-based 3D modeling technologies is transforming urban planning and architectural design by enabling digital twin creation and public engagement. However, research often lacks detailed comparisons of these technologies in terms of accuracy, adaptability, and sustainability implications.

This study bridges this gap by comparing UAV-based and web-based 3D modeling using the New York State Inebriate Asylum as a case study. A UAV generated a high-resolution 3D model, while a web-based platform created an alternative digital representation. Both models were evaluated against laser measurement data for spatial precision, adaptability to complex features, and versatility.

Results show that the UAV-based model excels in spatial accuracy and adaptability, particularly for complex terrains and architectural details, overcoming issues like uneven surfaces and distorted walls. Web-based models offer superior accessibility and real-time collaboration, making them ideal for participatory planning.
