WiMi Hologram Cloud, a Hologram Augmented Reality Technology provider, announced the construction of a holographic intelligent network system that integrates 6G and artificial intelligence technologies to promote holographic digital sensing, complete quantitative aggregation, refined control, smart execution, and integrated services in urban governance. The system can collect multi-source and multi-dimensional data, such as urban traffic and public safety. The system builds a unified digital twin-city model. It applies forward 3D modeling, 3D tilt photography, and point cloud holographic scanning to improve CIM spatial holographic information of roads and underground pipeline networks and BIM of important buildings.
