Three-dimensional roadway modeling system and method

Abstract

The invention provides a three-dimensional roadway modeling system and method, and relates to the technical field of information. The three-dimensional roadway modeling system comprises a roadway segmentation module, a calibration point setting module, a laser scanner, a sub-segment data processing module and a three-dimensional model calculation module. The roadway segmentation module is used for dividing a roadway into a plurality of subunit sections, and any two adjacent subunit sections are provided with overlapped sections. The calibration point setting module is used for setting a plurality of calibration points on the overlapping section; the laser scanner is used for performing three-dimensional laser scanning on the subunit sections to obtain three-dimensional point cloud data; the sub-segment data processing module is used for receiving the three-dimensional point cloud data of the sub-unit segment and establishing a sub-segment model according to the three-dimensional point cloud data of the sub-unit segment; and the three-dimensional model calculation module is used for judging whether any two sub-section models are adjacent sub-unit sections according to the calibration points on any two sub-section models, and splicing the plurality of sub-section models to establish a roadway three-dimensional model. The accurate roadway model can be established, and the roadway space condition can be accurately reflected.

Description

Technical field [0001] The present invention relates to the field of intelligent information technology, particularly, to a system and method for modeling a three-dimensional tunnel. Background technique [0002] Between the roadway surface and the ore is drilled out of the various paths of ore used, ventilation, drainage, and the pedestrian is necessary to prepare a variety of mining engineering freshly excavated ore and other metallurgical equipment. These pathways, collectively referred to as gateway. With the wave of information technology continue to expand mining and in-depth, the depth and breadth of information on mine construction is growing. Digital Mine, intelligent mine construction requires the exploitation of the object of mines, mining engineering, mining environment, mining behavior information simple, fast and efficient visualization and dynamically updated to be consistent with the production practice, to provide support for digital exploitation or intelligent m...

Problems solved by technology

There are relatively few modeling techniques for mine ramps. At present, manual methods are mostly used for modeling or two-dimensional plane drawings, which is inefficient and cannot meet the needs of rapid engineering visualization.
