City scene parameterization modeling system

Abstract

The invention relates to a city scene parameterization modeling system. The city scene parameterization modeling system is divided into a plurality of function modules according to parameterization and modeling separation system architecture design thinking and requirements for optimizing division of labor, and comprises a parameter management module, a service network module and an automatic modeling module, wherein a parameter set is guided into the parameter management module from a service network, the parameter management module performs centralized management and editing on the parameter set, the service network module provides functions of style library inquiry and editing, item original document uploading, item status and progress inquiry and three dimensional model downloading, and the automatic modeling module uses a file format conversion tool and a CGA rule library to automatically and rapidly generate a three dimensional model. The city scene parameterization modeling system separates parameter management from parameterization modeling, links the parameter management and the parameterization modeling through the web, enables a user to only need performing simple parameter management operation in a familiar AutoCAD (automatic computer aided design) software platform, automatically completes complex parameterization modeling processes through the automatic modeling module located at a service end, and thereby reduces a technical threshold for the user.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, and relates to a parametric modeling system of an urban scene. Background technique [0002] Digital city represents the development direction of urban informatization and is an important means to promote the informatization of the whole country. Since entering the 21st century, the digital city has developed rapidly and has become one of the most potential strategic high-tech fields. In various application systems of digital cities, 3D city models are gradually replacing 2D city maps, becoming the basis for many fields such as urban planning, urban management, public safety, heritage protection, traffic navigation, tourism and vacation, military defense, film and television entertainment, etc. Geospatial information representation. The construction of traditional 3D city models mainly relies on commercialized computer-aided design software, and adopts a large number of manual int...

AI Technical Summary

Problems solved by technology

However, this type of technology has a high technical threshold, mainly in the following aspects: it is modeled by formal or structured grammatical rules, so users must master a specific computer language and have certain programming capabilities; the types of urban features Rich and diverse, it is necessary to establish a huge grammar rule base to approach the complex spatial form of the real world; it is difficult to connect with traditional two-dimensional city model data, and it is inconvenient to edit

These problems have seriously restricted the application of parametric technology in the field of urban 3D modeling, and hindered the conversion of existing 2D city maps to 3D city models.
