报告简介：

3D buildings at different levels of detail (LoDs) are required calculations, simulations and visualizations in various applications in line with the United Nation Sustainable Development Goals. In this talk, Prof. Fan will present the recent research findings at NTNU for the purpose of generating 3D building models from LoD1 to LoD3 from multi-sourced GIS data, including Airborne Laser Scanning point clouds, OpenStreetMap data, street view images, aerial images, and even open sourced 3D city models. The research experiences will be shared for both deep learning-based approaches and traditional methods by defining parameters and defining rules.
