Abstract

The embodiment of the invention relates to the technical field of urban modeling. In particular, the invention relates to an urban model construction method and device. According to the method, a roadnetwork model of a target city is generated based on a satellite map; on one hand, entity modeling of a set building can be carried out in a road network model based on set landmark area data in a modeling instruction and obtained entity model parameters; on the other hand, white model modeling can be carried out in the road network model based on the satellite map, the modeling cost is effectively reduced on the premise that the city model precision is guaranteed, and therefore flexible modeling of the target city can be achieved.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of urban modeling, and in particular, relate to a method and device for constructing an urban model. Background technique

[0002] The rapid development of information technologies such as the Internet, the Internet of Things, and cloud computing has spawned big data beyond any previous era. Since the data itself is not readable, data visualization technology has become particularly important. Among them, the construction of city models and data visualization technology complement each other. City models enable people to monitor and manage cities more intuitively and efficiently. Combining big data with city models can help people understand the information behind big data and complete human Communication and exchange with "data".

[0003] It can be seen that the construction of urban models has far-reaching significance. However, the existing urban model construction methods are less...
