Embodiment Construction

[0043] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0044] The solid modeling method of the three-core arch roadway provided by the present invention collects roadway feature point data according to the section, calculates the spatial position of the section and the actual width and height of the section according to the spatial coordinates of the feature points, and combines the actual width and height of the section with the standard parameters of the three-center arch The spatial coordinates of the interpolation points on the arched roof are solved to form a section of the roadway, and the connection between the sections forms an entity. More specifically, the present invention comprises the following steps:

Abstract

The invention discloses a new entity modeling method for a three-core arch roadway based on cross-section measured data. By collecting spatial data of feature points on a cross-section, the spatial position and actual size of the roadway section are calculated from the three-dimensional coordinates of the feature points. The size is fitted with the standard parameters of the three-core arch, and a series of roadway sections with actual excavation size and accurate expression of the arch shape are generated at specific spatial positions. Then use 3D modeling software to create entities between two sections, so as to realize the establishment of the overall roadway model, and effectively solve the problem of continuous updating of the roadway solid model. The generated roadway solid model can truly reflect the shape of the roadway, which can fully meet the requirements Mining design, mining equipment layout planning and other requirements.

Description

technical field [0001] The invention belongs to the technical field of computer three-dimensional modeling, and in particular relates to a three-arch roadway entity modeling method based on section measurement data. Background technique [0002] A roadway is a passage dug in a rock mass or a mine layer during underground mining, and is used for mining, transportation, ventilation, drainage, power supply, etc. In two-dimensional mode, the roadway is abstractly displayed as double lines, which can only represent the width and plane coordinates of the roadway, but cannot display the spatial position of the roadway, let alone fully display the spatial shape of the roadway. With the maturity of computer three-dimensional modeling technology and the requirements of visual management of mining production, it is necessary to model the tunneling roadway to truly reflect the actual size and real spatial position of the underground roadway project, which is used for mining design and m...
