Introduction
This is the user manual of the Amberg Tunnel 2.0 - Tunnelscan module. It contains all infor-
mation about scan measurements, processing and analysis.
This manual builds on the manual Amberg Tunnel 2.0 - Base. General information about the
software, e.g. creation of projects, definition of headings, axes, construction stages, etc., can
be found in the manual Amberg Tunnel 2.0 - Base.
1 What is Amberg Tunnel 2.0 - Tunnelscan
Amberg Tunnel 2.0 - Tunnelscan contains the modules Amberg Tunnelscan Basic and Amberg
Tunnelscan Plus.
The module Amberg Tunnelscan Basic serves the management, analysis and reporting of
measured point cloud data from a tunnel project. Measurement data from various sources can
be imported, managed, analyzed and converted to reports. A tight integration with the field
software Amberg Navigator Tablet allows an automated data synchronisation.
On top of the functionality of Amberg Tunnelscan Basic, Amberg Tunnelscan Plus offers
more analysis types and advanced export functionality.
2 Scanner measurements in general
Doing scan measurements at the different construction stages of the tunnel documents the as-
built geometry, allows deviation checks and layer thickness calculation. Scan measurement
and evaluation is a repetitive task executed on each underground site on a daily basis.
Amberg Tunnelscan will support you to manage and analyse your measured scans in a seam-
less work flow. Minimizing the time from measuring the scan data to handing out the reports
to your customer improves your efficiency.

Chapter 1 General introduction
1.1 General work flow
The general work flow when working with Amberg Tunnel 2.0 - Tunnelscan consists of the
following steps:
1. Create a new project with the New project wizard. Please refer to the Amberg Tunnel 2.0
- Base manual for more details.
2. Input the design data of the project like tubes, sites, headings, axes, construction stages
with theoretical profiles and theoretical sections. Please refer to the Amberg Tunnel 2.0 -
Base manual for more details.
3. Import measurements to a construction stage through measurement data synchronisation
with Amberg Navigator or using import functionality in the Measured point clouds editor.
4. Create a analysis using the New point cloud analysis wizard.
5. Customize the Analysis settings to your needs.
6. Check the measured scan data and create graphical or tabular reports.
7. Import new measurements, analyse and create reports as the project continues.
1.2 Concepts
This chapter describes the most important concepts of Amberg Tunnel 2.0 - Tunnelscan. Fur-
ther basic concepts are explained in the chapter Concepts in the manual Amberg Tunnel 2.0
- Base.
1.2.1 Measurements and construction stages
In an Amberg Tunnel project, each heading has a Measurements node which handles vari-
ous types of measurement data. Measured point clouds are managed per construction stage,
allowing comparison between construction stages and easy filtering to keep the overview. In
the point clouds editor, all imported point clouds are stored, listed and displayed. The user can
check the imported point clouds and clean up the data if necessary.
1.2.2 Measurement source independence
Measurement data can be synchronized with Amberg Navigator Tablet enabling the user to
handle design data as well as measured data in Amberg Tunnel 2.0. For being independent
of the measurement source, also scan measurement data from other devices can be imported
with the flexible ASCII import wizard. Pointclouds available in other formats (e.g. ZFS, PTS,
FLS, PCD, LAS/LAZ) can be also imported to the Point clouds editor.
1.2.3 Analysis setup
When creating a new point cloud analysis, a wizard helps to configure the essential settings.
During this process, the user is asked to specify construction stages from which the design
data and the measurement data are used.

General introduction User manual
Page 8 of 68 © Amberg Technologies, 2018
1.2.3.1 Design data
The construction stage set as Reference construction stage in the settings is used to read the
design data from. The design data (theoretical profiles, theoretical sections, transverse slope,
block information) of this construction stage is used for all the calculations.
1.2.3.2 Line scan analyses
In a point cloud analysis of type Line scan, the user can select one or multiple construction
stages to analyse the measured point clouds.
1.2.3.3 Blasting round scan analyses
In an analysis of type Blasting round scan, the user can select one or multiple construction
stages to analyse the measured point clouds. The measured point clouds of different excava-
tion steps can be automatically merged together without any manually masking of the data.
Only the relevant parts of the scan will be used to create the model. The result will be a com-
plete measured model of the tunnel from different scans.
1.2.3.4 Layer thickness analyses
The user can select a construction stage as Original construction stage. The measured point
clouds of this construction stage will be used as original point cloud for deviation calculation.
Furthermore, the user can select a second construction stage as Comparison construction
stage. The measurements of this construction stage will be calculated against the one of the
original construction stage to derive deviation values.
1.2.3.5 Undulation analysis
The analysis type Undulation is made for a evenness control of the tunnel surface. The user
can select one or multiple construction stages to analyse the measured point clouds. The mea-
sured point clouds will be used for evenness calculation of the tunnel surface. This analysis
is used for quality cheeks of the shotcrete before the membrane system for waterproofing will
be applied in the tunnel.
1.2.4 Calculations
1.2.4.1 Deviation
The deviation value represents a distance to a 3D model. The distance is calculated on a
straight line perpendicular to the theoretical model of the reference construction stage. It starts
from the measured point and ends at the intersection with the theoretical model.
1.2.4.2 Under-/overprofile area
The under-/overprofile area is calculated by intersecting the current profile either with the the-
oretical profile (for analysis type measured vs. design) or with the profile of the original con-
struction stage (for analysis type measured vs. measured). All areas that are outside of the
profile, are summed up to a total over profile area value. All areas that are inside of the profile,
are summed up to a total underprofile area value.
1.2.4.3 Over- / under profile volume
The under-/overprofile volume is calculated by multiplying under-/overprofile area values of a
measured profile with the stationing difference to the next one.

User manual General introduction

1.2.4.4 Area classification report
This application allow to calculate the classification values for the point clouds (e.g. under- and
overprofile). These values define how many points of all measured points are within a defined
range e.g. how many points have an under profile value between 0.2 and 0.3m. This is only
a text report stored in TXT.
1.2.4.5 Area coverage report
This application allow to calculate the coverage percentage values for the point clouds. These
coverage values define how many points of all possible grid points are measured. This is only
e text report in TXT.
1.2.5 Create analysis once, reuse many times
To work efficiently with Amberg Tunnel 2.0 - Tunnelscan it is recommended to create analyses
for a certain purpose, customize them to your needs and reopen when new measurements
need to be evaluated or reports need to be delivered. Every time after new measurements have
been imported to the project, the analysis can be reopened. This will automatically recalculate
and update all diagrams to the new data. All settings remain unchanged to make sure the
generated reports stay consistent over time.

3.5.6 Point cloud filter
To filter a point cloud manually in the detail editor use the filter tools in the point cloud filter
dialog. Normally only points in a defined distance around the scanner should be used for the
analyses. The accuracy of closer points around the scanner center will have a higher absolute
coordinate accuracy the points far away. More than 80 percent of the scan points will be in
overlapping areas (e.G. Available in a other scans). That points can be also filtered to increase
the performance of the analyses significant. To use the analyses later in a full automatic way
it is recommenced to have only two different CS measurements in one scan (E.g. excavation
and shotcrete layer 1 or shotcrete layer 1 and shotcrete layer 2). Other CS in the same scan
can be copied to a other CS point cloud measurement folder.
There are two different filter types available.
The filter are also in the point cloud editor available without open every scan manually
Filtered points are deleted from the project and are not available for other analyses.
Distance filter The distance filter selects all measured points from the center of the
scanner up to a defined range. Input the distance value or move the
slider to the distance that should be used for filtering. Select if points
inside ore outside of the defined sphere should be filtered.
Plane Filter The plane filter selects points on defined HS/TM values. Input the dis-
tance value or move the slider to the distance that should be used for
filtering. Select if points inside ore outside of the defined planes should
be filtered.
