A digital-analog separation method for a city information model

Abstract

The application provides a digital-analog separation method for a city information model, relates to the field of building informatization, and comprises the following steps: S1, establishing a system and a reference; S2, topological correlation; S3, multi-source data space-time synchronization and grid correlation; S4, space-time constraint standardization analysis; S5, target grid generation; S6, three-dimensional visualization output; and S7, statistical result output. The method can realize logical decoupling and dynamic recombination of a geometric model and business data, solves problems such as model bloating, poor reusability, low statistical efficiency and data island caused by strong coupling of a BIM model, and realizes the leap of building digital twinning from'single-scene customization' to 'full-life-cycle reuse'.
