Automatic generation method of 3D architectural model of subway station

Abstract

The invention relates to a method for automatically generating a three-dimensional building model of a subway station, comprising the following steps: step 1, obtaining station parameters and room parameters; step 2, generating outlines for arranging rooms according to the station parameters and room parameters; step 3, according to The type and room priority of the station room, and the area priority of different areas of the outline, and arrange the rooms in different areas within the generated outline; step 4, generate a three-dimensional building model of the subway station according to the result of the arrangement of the rooms . The invention has the following beneficial effects: the room layout is fast and efficient; the design method is easy to learn and has strong adaptability; the design scheme is more reasonable and the design quality is guaranteed through algorithm optimization.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of construction engineering, in particular to a method for automatically generating a three-dimensional building model of a subway station. Background technique [0002] At present, in the construction of rail transit facilities (such as subway stations), 2D CAD technology is mostly used in the planning and design process of subway construction, mainly based on two-dimensional drawing planning and design. Designers draw lines and blocks, and constantly Considering various factors and conditions, and constantly revising, gradually complete the plane and three-dimensional design of the subway station. [0003] The above-mentioned process leads to the following problems: it takes a long time for the designer to modify the design later; the special design manually made by the designer has a high probability of error; during the review of the pipeline relocation design, it is difficult to...

Problems solved by technology

[0003] The above-mentioned process leads to the following problems: it takes a long time for the designer to modify the design later; the special design manually made by the designer has a high probability of error; during the review of the pipeline relocation design, it is difficult to modify and demonstrate the modification suggestions put forward by the participants on the spot , which increases the difficulty of review and reduces the efficiency of review, and it is not easy to find problems and prone to design defects

[0004] In short, the existing subway station workflow can easily lead to difficult identification of project points and difficulty in information coordination, which greatly increases the risk of project construction

These traditional planning and design techniques have been difficult to meet the needs of modern subway construction
