Abstract

The invention relates to a method for modeling an underground roadway three-dimensional scene by CAD (Computer Aided Design) drawings, which is used for reducing the modeling workload and improving the modeling efficiency and belongs to the fields of three-dimensional graphic modeling and software development. According to the technical scheme, the method comprises the following steps: firstly, converting a CAD drawing into a vector data format, and carrying out reading, storage, analysis and formatting processing on point data, line data and text data in the vector data format to obtain three-dimensional graph basic data; and then rendering the three-dimensional graph basic data by utilizing a graph engine to obtain a three-dimensional tunnel model, and finally constructing a graph editorto edit a three-dimensional scene. Manual drawing of an underground roadway by means of modeling software is avoided, and the purposes of reducing the modeling workload and improving the modeling speed are achieved.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method for modeling a three-dimensional scene of an underground roadway with a CAD drawing. Background technique [0002] The 3D modeling technology of underground roadway can be realized by manual drawing with 3D modeling software. It is widely used in the existing coal mine underground monitoring system, but it has long modeling time, heavy workload, and software that cannot be implemented in B / S architecture. system compatibility issues. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method for CAD drawings to model the three-dimensional scene of underground roadway, including: [0004] By reading the data in the CAD drawings, analyzing and distinguishing the types of data read, and formatting different types of data into the basic data of the three-dimensional graphics required for ...
