Description
Technical field
The present invention relates to methods underground chamber geological object positioning and edited and recorded, and survey more particularly, to based on Handheld laser
The underground chamber geological record method of distance meter.
Background technique
Since underground chamber does not have GPS signal and mobile network, and the geological object of the underground chamber described is needed to have
Have greatly small, the smallest structural plane reaches Centimeter Level, it is desirable that precision is high.It is to use skin that traditional underground chamber, which positions and edits and records mode,
The equipment tools such as ruler, steel tape, circumferentor come measure cavern exposure geological object (stratigraphic boundary, structural plane, weathering
Line etc.) the geometrical characteristics such as position, development length, thickness, then manual machine plotting is drawn on papery centimetre paper, circumferentor institute
The structural plane occurrence information of acquisition is recorded on table or minute book, eventually passes back to interior, then pass through computer scanning vector quantization
Live graph, digitlization paper record carry out the application such as later period statistical analysis.This traditional method not only heavy workload, efficiency
It is low, and it is difficult to ensure the accuracy of measurement data.
With information-based development, emerge some can carry out digital collection to underground chamber geological object information at present
Software, equipment, summary be based primarily upon following four principle respectively: 1, ruler measure, by hand by coordinate it is defeated arrive acquisition system；2,
Photograph, image procossing principle；3, laser point cloud scanning technique principle；4, laser ranging positions.
1, ruler measures, manually enters coordinated manner: although being put in storage together with attribute information, realizing unified management, and energy
It is enough that display diagram is generated according to relative coordinate, reduce the workload of industry in the later period, but needs a node in tested cavern
The input relative coordinate of one node records the spread situation of geological object in cavern, for developing pair irregular, more than node
As node Input Process consumes a large amount of manpower and time.
2, photograph, image procossing principle: requirement of taking pictures has certain overlapping to cover entire cavern, be then return to it is indoor into
Row splicing, then describe corresponding geological object just on photo and can be carried out specific positioning, fixed pedestal is needed in operating process, is grasped
Make cumbersome, low efficiency, and is influenced to return to room with limitation in use by environment such as cavern's space size, dust
It is interior to pass through a large amount of data processing work, it can just see substantive Geological Achievements.
3, laser point cloud scanning technique principle: establishing tested hole wall physical model by scanning, although process is fast, after
Phase needs denoising, splicing, interpretation when utilizing, and increases interior work amount, requires staff's total quality high.
4, laser ranging positioning principle: currently used for a kind of laser ranging position indicator of underground geological structure ranging localization,
Its component is more, including host and locating rod two large divisions, and when operation is completed thick by running fix set square and stubborn bolt
It reconciles fine tuning, there is a large amount of geology exposure lines in cavern, one goes out naked wire and has several nodes, and the process of coarse adjustment and fine tuning is too cumbersome
And it is time-consuming, and what is measured is all most basic angle and relative distance, and practical height difference and horizontal distance will be according to surveys
The basic parameter conversion obtained can just obtain, and statistically analyze inefficiency.

The invention has the advantages that improving work efficiency, the time is both saved to a certain extent, reduces security risk,
The data inputting work in turn avoiding returning to interior industry, improves the accuracy of data.It can be checked at any time while acquiring information
Display diagram, check are edited and recorded as a result, convenient for error correction, avoid returning to the fiber crops for entering underground chamber verifying after indoor discovery mistake again
It is tired.It embodies are as follows:
1, by hand-held laser rangefinder and the system that the mobile phone of Android operation system constitutes is installed, realizes ground
Geological object each node coordinate in lower cavern is calculated, is edited and recorded, being directly put in storage automatically, therefore does not have to be recorded in other media to return to
Interior re-types, and avoids unnecessary hand and misses mistake.
2, hand-held laser rangefinder operating process is simple, only laser point need to be got to the point to be surveyed, do not have to frame pedestal,
The operation such as framing, adjustment, and avoid the defeated coordinate process of cumbersome hand.
3, it is directly associated with acquisition with geological property, is managed collectively, it is convenient to carry out information inquiry, statistical analysis, scene at any time
It can be directly viewable display diagram, industry processing workload in the later period is reduced to nothing, eliminates the picture vector quantization mistake of photographing principles
