Abstract： The city′s 3D model is a bridge connecting physical space and digital space as a three-dimensional visual representation of urban physical entities, and it′s also a key foundation for the realization of urban digital twins. This paper studies the current digital 3D reconstruction technology and application of cities, and summarizes the multi-scale full-element modeling method of "sky, ground and room element". The challenges and trends of digital twin urban 3D reconstruction are analyzed.
