NVIDIA Expands Omniverse Blueprint for AI Factory Dital Twins

3d twinA dital twin is a virtual representation of a physical object, system, or environment. With up-to-date data bundled in one place, a dital twin evolves with the flow of information from sensors,Abstract. 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:
