TcpScancyr for Tunnels

Demonstration Guide for

Minimum System Requirements

Operating System Windows XP / Vista / 7 in 32 and 64 bits

Peripherals Mouse, CD-ROM Drive

Graphic Card Minimum resolution 1024x768 pixels, compatible with OpenGL

Disk 10 Gb free space

Memory Minimum recommended 2 Gb

Installation of Sample Files

Uncompress Data.zip file in folder TcpScancyr Projects to your disk drive. To perform

the tutorial we will use the following files in the Tunnel folder:

File Name Format Description

demo*.xyz Text Point cloud

Alignment.xml LandXML Horizontal and vertical alignment

Template.dxf DXF Tunnel template design

Control.txt Text Template control points

Project Definition

The files used for this sample were gathered from a tunnel for a suburban train in San

Sebastián (Spain). The data have been filtered in length (400 m) and density (50 %) for

the sake of ease.

1. Run File > New. Assign as project file Project1 and press OK.

2

2. To define horizontal and vertical alignment, run File > Import > Import LandXML

Alignment, and choose file Alignment.xml.

3. Each file can have more than one alignment. Now confirm the selection of alignment

named EPP and press OK.

4. In table of contents, open Project1, select Horizontal Alignment, and view the

analytical definition of horizontal alignment. Activate View tab in order to show the

graphic view.


3

5. Repeat if desired the same process with Vertical Alignment. Apply x10 as Vertical

Factor.

6. Run Points > Manage. Press Open button, select as file type Points file (*.txt,

*.pun, *.xyz) format and choose all files from demo-1.xyz to demo-8.xyz. Press

OK to import and analyze the points (about 3 minutes in a Intel Quad Core with 4 Gb

of RAM).

7. Go again to Points > Manage to examine definition of points loaded: about twelve

million points in eight scan sessions.

8. Run Points > Symbology, select option Intensity with gray palette and press OK.

9. Run File > Save as and save project in folder Topcon1 as Tunnel1.pro.

Points Management

1. In table of contents, expand Points cloud and select some of the scan sessions or

All to view the whole point cloud.

2. Experiment with view controls: Zoom window, Zoom extension, Pan, orbit, zoom

in real time with mouse wheel, etc. Then try buttons Top view, Front view and

Right view.

3. Now Press Orthogonal/Perspective button and move the station slider to go

forward and backward along the alignment.


5

4. In Orthogonal mode, run Points > Filters and activate Angle tab. Experiment

moving the sliders Station, Angle and Radius and close the window.


6

Cross Sections

1. Run Cross Sections > Calculate Cross Sections. Create a new cross section file

named Tunnel1.trb. Enter values for Initial Station, then enable Manual Center

and enter Gradient Distance and Bandwidth values as shown in the figure and

press OK to start calculation.

2. In the table of contents, expand Cross Sections > Tunnel1 and select Station

3+230. If needed increment point size pressing Increment button.


7

3. Now press Select by Polyline icon, and draw a polygon so that the points that

belong to the ventilation pipe be selected. Press right button, then Select and

Delete Selection. Now you can see that filtered points are marked and cross

section has been recalculated.

4. Move cursor in orbit mode so that points can be seen in 3D. Activate View tab and

assign in Points cloud edit box a value of 5 to see a bandwidth of 2,5 meters at

both sides of cross section.


8

5. The cleaning process can be repeated by using the different filtering tools, not only

for each profile, but for longer segments. For instance repeat the process to clean

points of total station and tripod at station 3+237.

6. Now we will open a project with points filtered. Save current project and then run

File > Open, and choose file Tunnel2.pro in folder Tunnel2. In the table of

contents, expand Cross Sections > Tunnel2 and navigate through cross sections

computed from a clean point cloud.


9

Template Definition

1. Run Tunnel > Define Templates. Input 2.0 in Bench Height field and press OK.

2. Run File > Import > Import DXF, and choose file template.dxf from Tunnel

folder.

3. Press icon Copy with reference point and select polyline which define the

template. To specify precisely origin point, press icon Final Point and select

application point of vertical alignment.


10

4. Activate Template1:Layer1 tab, and press Edit > Paste or CTRL-V.

5. Now we will define control points needed to compute real alignment. Activate

Control Points tab and press button Open. Select file control.txt from Tunnel

folder.

6. Run File > Save Definition, OK and then File > Quit.


11

7. Activate tab Profile in the Profile window. Press Compare button and then Ok in

the next dialog.

8. In the layers control hide layers Points and Filtered Points. Activate tab View and

enable Dimensions, Inside and Outside options. Navigate through stations to view

the infra and over-excavated areas.

9. Run Cross Sections > Export to DXF. Press OK and set the options as shown in

the next dialog. Press OK again.


12

10. Using come CAD software, open DXF file generated and view cross sections running

Zoom Extension command. You can use CAD’s layer control to show or hide specific

layers.


13

Reports

1. Run Tools > Areas Report and select Templates as Report Type, and then

activate Top Heading and Bench options. Press OK.

2. The reports for complete excavation, advance and destroy are shown. Pressing

Export button can be exported to text, Excel or HTML files.

3. Run Tools > Alignment Deviation Report. Select Control Points as Method and

press OK to start calculation (about 3 minutes).


14

4. The report is shown giving horizontal and vertical differences for each station. Also is

created a new layer Real alignment that is drawn over the horizontal and vertical

alignment views.


15

Inspection Map

1. Run Tools > Inspection Map. Enter parameters as shown in the figure and press

OK.


16

Tunnel Route

1. Run Tunnel > Route and maximize window. Hide layers Cross Sections, Cross

Sections with texture and Template1:Layer1. Enter as Station 3200, press

Enter and then Play.

2. Optionally run File > Export, select compression Codec and quality and generate a

video file in AVI format.
