Embodiment 1

[0040] Real scene 3D geological cataloging system, such as figure 1 Shown: including capture module, repeat module, processing module and catalog module.

[0041] The shooting module is used to shoot multiple roadway images along the advancing direction of the tunnel axis in a fixed shooting state, and send the roadway images to the processing module. The roadway images can be stored by the existing memory and then acquired by the processing module. The shooting module Photographic equipment available for mine photography.

[0042]The repeating module is fixedly installed on the shooting module, and the repeating module is used to collect the change information during the shooting process, and identify the repeating position and repeating rate between the captured images according to the changing information, and the repeating module judges whether the repeating position is the same as the preset position, judges Whether the repetition rate is within the preset range, when th...

Embodiment 2

[0053] The difference from Embodiment 1 is that the real-scene 3D geological cataloging system also includes a drawing module, which obtains the cataloged result map and generates a roadway profile according to the geological information, and the map generating module generates the roadway profile through the existing AutoCAD software.

[0054] It also includes a real-scene module. The real-scene module is used to sequentially generate a real-scene display model from the roadway images according to equal durations. The real-scene display model is realized through the existing three-dimensional roaming technology. When setting geology, the processing module adds the real scene display model to the roadway section.

[0055] The real scene three-dimensional geological cataloging method also includes the following contents:

[0056] Content five, obtain the cataloged result map through the map output module and generate the roadway section map according to the geological informati...

Abstract

The invention relates to the technical field of geological record, in particular to a real scene three-dimensional geological record method and system. The system comprises a shooting module, a repeating module, a processing module and a record module. The method comprises the following steps: making a shooting module shoot a plurality of roadway images in the tunnel axis advancing direction of a roadway; making a repeating module on the shooting module collect change information in the shooting advancing process, keeping an overlapping degree system among the multiple roadway images according to the change information, and sending a shooting prompt to the shooting module by the repeating module; acquiring roadway images through a processing module, sequentially adding sequence identifiers, and sending the roadway images added with the sequence identifiers to a recording module; and recording the roadway image through a record module to obtain a record result graph. According to the invention, errors of roadway record can be reduced.

Description

technical field [0001] The invention relates to the technical field of geological cataloging, in particular to a real-scene three-dimensional geological cataloging method and system. Background technique [0002] In the mining activities of the mine, it is necessary to excavate in advance to form a roadway with preset functions, such as serving a mining area or more than one mining face, equipment transportation and coal mine transportation. Due to the relatively high traffic frequency of the roadway, during the mining process, the inner wall of the roadway usually needs to be supported by safety nets or other device structures, because the spraying will affect the passers-by or moving objects, so as to protect the passers-by in the roadway or the safety of moving objects. During roadway excavation, when a geological change is found, such as a fault, a rough and simple record is usually made for the geological change. For example, the recording method for the geological cha...
