Abstract

Abstract:

In order to achieve rapid construction and visual characterization of 3D mine scenes, a fast generation method of 3D mine tunnel model based on opensource program was proposed considering the drawbacks of current method, such as great difficulty and poor operability. Firstly, based on collected mine shaft and lane attribute information, automatic import and standardized storage of data were realized with help of MySQL database. Then, geometric characteristics of connecting roadway were explored, different types of roadway, including conventional straight, inclined and vertical roadway, were deconstructed, and parameterized expression of 3D model was proposed. Then, Python and blender development platforms were used to generate 3D roadway system model. Finally, T type and Y type connecting roadways and typical development models were reconstructed rapidly to verify effectiveness of this method. The results show that the proposed parametric modeling method simplifies 3D modeling into "parameter + algorithm", thus achieving rapid construction of 3D tunnel model, and it also solves problems like distortion. Moreover, the developed system platform can realize rapid construction of mine virtual scenes based on key data.
