Description

Technical Field

[0001] The present invention relates to the field of digital twin technology, and in particular to a static digital baseboard data acquisition device and a static digital baseboard construction method. Background Art

[0002] As the core foundation of the digital twin platform, the static digital baseboard provides the initial space and static data of the twin model. On this basis, the digital twin platform realizes more complex digital scene management through dynamic data loading, model calculation and interactive functions. The two work together to build a modern and intelligent digital system.

[0003] However, the existing digital baseboards still have some shortcomings in data collection and construction methods. For example, in traditional technologies, digital baseboard construction often relies on scattered equipment, such as separate aerial photography drones and air monitoring equipment.
