Twin it! 3D for Europe's culture

3d twinAbstract. In this article, we propose a 3D mobile crowdsensing (3D-MCS) framework aimed at sustainable urban dital twins (UDTs). The framework comprises four key mechanisms:More accurate 3D reconstruction and maps; Faster time-to-market to develop your own mobile mapping device; Lower required sensor cost and flexibility of Lidar choice; Hher productivity
