Abstract

The invention relates to the technical field of automatic three-dimensional modeling, in particular to an automatic parameterized three-dimensional pipeline modeling method and system based on a GIS system. The method includes: obtaining original geophysical prospecting data, the original geophysical prospecting data including point data and line data of corresponding pipelines respectively stored according to pipeline types; performing validity and completeness detection on the original geophysical prospecting data to obtain validity and completeness detection Geophysical prospecting data; traverse all geophysical prospecting data to obtain the center point, and create the center point as the origin of the local coordinate system of the model; traverse the point data and line data of the pipeline in the geophysical prospecting data, use the center point as the origin to convert and draw the required coordinates and generate the A 3D pipeline model in a spatial reference system is required. The invention automatically generates a three-dimensional pipeline model in a required space reference system with minimal manual operations, realizes automatic connection between pipelines and pipe points, appendages, and feature points, fits the ground, and forms nearly real three-dimensional visualization model data of underground pipelines.

Description

technical field [0001] The invention relates to the technical field of automatic three-dimensional modeling, in particular to an automatic parameterized three-dimensional pipeline modeling method and system based on a building information model (BIM) and a geographic information system (GIS) system. Background technique [0002] In the geographic information system (GIS) project of three-dimensional comprehensive pipeline or professional pipeline, it involves the modeling of various types of pipelines such as electric power, telecommunications, water supply, drainage, heat, gas, etc., and the structures, There are many sizes, and different types of pipelines have slightly different definitions of some attributes such as caliber and buried depth, and the coordinates of their geophysical source data mostly use CGCS2000 (China Geodetic Coordinate System 2000) coordinates, and some geophysical units use offset local coordinates Tie. Using manual modeling will face many problems...
