specific Embodiment approach
[0078] From the excavation engineering plan uploaded by the user to the standardized excavation engineering plan, as a specific implementation method, the following data processing process is carried out:
[0079] 1) Receive the excavation engineering plan and its coordinate range uploaded by the client;
[0080] 2) Using the graphical application platform—ODA (Teigha) to identify the entity information of dwg (the file format used by CAD) files, including layers, extended attributes, styles, etc.,
[0081] 3) Using the slice cache technology, use [layer, slice level, slice encoding [0,0], [0,1], ... [9,9]..., png image binary storage data] data structure to store ;
[0082] 4) Determine whether the content of the dwg file is uploaded for the first time. If it is the first upload, define the version number for the first time. If the content of the dwg file is updated and uploaded, enter the update data process and update the latest version number.
[0083] 5) Establish a mon...

[0084] The present invention also provides an implementation manner of quickly updating and providing a standardized plane engineering drawing in step S11, specifically including:
[0085] Select the layer and slice the theme map according to the level of the selected layer;
[0086] Obtain the layer code of the changed area and the information in the theme map;
[0087] Update and store the image code and its information in the theme map, and provide the updated planar engineering drawing.
[0088] The present invention can obtain the corresponding roadway 3D view through the maintenance and update of the plan view.
[0089] Carry out the topological representation and initialization of the roadway according to the normalized plan, including:
[0090] Use n discrete point sequences to represent the section of the roadway from the side of the ground: use parameters to describe the roadway section, such as circular arc dome, semicircle dome, three-center dome, trapezoidal dom...

Abstract
The invention discloses a visualization method for a mine holographic image. The method comprises the steps of collecting roadway data through a collaborative design platform; storing the acquired roadway gob data; formatting the stored roadway empty data, wherein the formatted roadway data comprises roadway information and lead point information; conducting wire smooth transition processing on the formatted roadway data; and performing three-dimensional rendering on the roadway data subjected to the smooth transition processing. Through the method and the device, the 3D model roadway and thetexture map can be automatically generated based on the engineeringplanar graph, so that three-dimensional display of the roadway can be realized based on the two-dimensional image and related information, and virtual realityroaming of a roadway scene is further realized.
Description
technical field [0001] The invention belongs to the technical field of mine engineeringinformatization, and in particular relates to a visualization method for a holographic picture of a mine. Background technique [0002] The production environment of coal mines is complex and changeable. In order to achieve safe production in coal mines, it is necessary to closely cooperate with departments such as coal mine surveying, one communication and three defenses, electromechanical, production, and monitoring. Coal mine production is also a dynamic and real-time changing process. With the mining of coal mines, various data are changing in real time. Therefore, it is necessary to update the real-time data of various departments in a timely manner and provide integrated data for the required topics, scenes or locations. [0003] Although there is a coal mine management system with a "one-map mode" disclosed in the prior art, which discloses the architecture of the management system...
