Automatic generation method of 3D model of subway station

Abstract

The invention relates to a metro station three-dimensional model automatic generation method. The method comprises the following steps of 1, obtaining station parameters and room parameters; 2, generating contours used for room arrangement according to the station parameters and the room parameters; 3, according to types and room priorities of station rooms and region priorities of different regions of the contours, performing the room arrangement in the different regions of the generated contours; 4, according to a room arrangement result in the step 3 and the station parameters, obtaining spatial information of a path used for pipeline arrangement, wherein the path is divided into multiple path segments, and the spatial information includes path segment information used for recording thepositions of the path segments; 5, obtaining end point information and pipeline size information of pipelines needed to be arranged; and 6, according to the information obtained in the steps 4 and 5,performing the pipeline arrangement, and according to the room and pipeline arrangement results, generating a metro station three-dimensional model.

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 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] In addition, after the station room layout is completed, it is necessary to continue to lay out a large number of various pipelines. The pipelines involved in each subway station range from a dozen to several hundred. Not only are there a large number, but also various types, involving v...

Problems solved by technology

[0004] 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

[0005] 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
