Method and device of achieving three-dimensional modeling of wisdom building

Abstract

The invention is suitable for the technical field of wisdom buildings and geographic information science and provides a method and a device of achieving three-dimensional modeling of a wisdom building. The method of achieving 3D modeling of the wisdom building comprises that constructing a data model which is corresponding to the wisdom, carrying out a 3D modeling of a building example, generating the 3D modeling of the building example, confirming an object region of the building example, extracting parameters of a reverberation time of an acoustic environment influencing the object region, calculating the parameters of the reverberation time of the acoustic environment of the object region under each frequency, at last, forming a reverberation time analytical curve according to the parameters of the reverberation time of the acoustic environment under each frequency, comparing the reverberation time analytical curve with a best acoustic environment reverberation time, obtaining an acoustic environment reverberation time analysis result and updating the 3D modeling of the building example according to the analysis result. Due to the fact that a mathematical model simulation and a mathematical model analysis of the acoustic environment reverberation time is carried out on a result of all kinds of objects optimizing in a real building in order to choose best objects combination and therefore constructing requirements of the wisdom building is met.

Description

technical field [0001] The invention belongs to the technical fields of smart buildings and geographic information science, and in particular relates to a method and a device for realizing three-dimensional modeling of smart buildings. Background technique [0002] Smart buildings refer to building as a platform, with construction equipment, office automation and communication network systems, integrating structure, system, service, management and the optimal combination between them, providing people with a safe, efficient, comfortable and convenient building surroundings. Its construction process is divided into three processes: design, construction, and installation. Among them, the design stage is the basis of these three processes of smart building construction. The design drawings and analysis results of this stage are the general guidance and general basis for the construction of smart buildings. [0003] The simulation and analysis of the acoustic environment in bui...
