• When the base unit and the mirror unit are ready, the Motor LED will stop flashing and remain green.

4.2 Installing and using the software

4.2.1 Step 6 – (Software installation)

If FARO Record is not already installed on your PC, insert the CD supplied with the scanner and follow the installation instructions on the screen.

4.2.2 Step 7 – Establishing an Ethernet connection to the scanner

Run FARO Record and click on the symbol

to select your scanner by a left-click on the scanner’s name. Open the context menu with a right-click to connect to the scanner.

The status icon will change to “Connected” after the connection has been established and the “start scan”-symbol ( ) will become activated ( ).

Fig.10 FARO Record – scanner selection

4.2.2.1 Connection problems

A connection can only established if the scanner and the operating PC have compatible IP addresses and compatible subnet masks. If they don't, this is indicated by the Net incompatibility icon . You can check the parameters on the operating PC using the command ipconfig in the windows command prompt.

Page 16

User’s manual FARO Laser Scanner LS 16

Fig.11 Checking IP address with ipconfig

If the operating PC has no valid IP address (like in Fig.11) you might have to assign a static IP address to the PC. If the operating PC is part of a LAN, ask your system administration to do this. Else you can configure the operating PC's IP address in Windows' Control Panel  Network Connections  Local Network Connection (LAN)



Properties  Internet Protocol (TCP/IP)  Properties, using the option "Use the

following IP address" and providing a valid IP address and subnet mask.

Fig.12 TCP/IP Properties

If the scanner selection dialog shows a net incompatibility you have to change the IP address of the scanner remotely. Select the command Set IP address form the scanner's context menu as shown in Fig.13.

Fig.13 Net incompatibility problems

Change the IP address of the scanner to an address that only differs from the operating PC's IP address by the last number. The subnet mask of PC and scanner should be identical. If you sometimes have the scanner connected to your LAN, ask your system administrator for a yet unused IP address.

Fig.14 Changing the Scanner's IP address

User’s manual FARO Laser Scanner LS 17

4.3 Starting a scan

4.3.1 Step 8 – Unlocking the laser

• Insert the key into the lock and turn it to the On position.

• The Laser LED will flash green while exchanging parameters with the

PC unit.

• A red light on the upper part of the scanner and the green Laser LED will indicate that the laser is unlocked and ready for scanning.

If you are in a distance less than the eye safety distance, wear your laser safety glasses now and take care that there are no people in the potentially dangerous area unless they are wearing laser safety glasses.

Remember that the scanner is turning and the mirror unit is rotating with a high speed. Ensure that the scanner can move freely and that no objects can touch the mirror unit.

4.3.2 Step 9 – Scanning

You can start your first scan either by clicking on the symbol

(Start Scan) in FARO Record, or by pressing the Start button on the scanner. The software might ask for a name and a place for saving the scan. After this, the scan starts and a progress bar will be displayed.

In the very first scan after the scanner has been switched on, the scanner starts turning counterclockwise for a brief moment. Then it stops and starts scanning in clockwise motion. All consecutive scans are then taken without the initial counterclockwise motion. On completion of the scan the scanner rotates counterclockwise back into its initial position.

The result of the scan will be displayed on the screen.

4.3.3 Step 10 – Shutting down the scanner

Lock the laser by turning the key to the Off position. Use the On/Off button on the scanner (pressing it for at least 5 seconds) or the FARO Record Software to shut down the scanner.

7 Color Option

With the color option, you can take scans in which each scan point has not only its 3D information, but also color value associated with it.

Fig.19 Scans with color

This is done by a combining the ordinary scanner with a digital camera. The digital camera is hooked onto the scanner and controlled by the scanner software.

When a color scan is taken, the scanner first performs a normal scan. Then it takes a turn to determine a balanced exposure setting. Finally in a third turn the digital pictures are taken.

7.1 Initial Setup of the camera

Before you can use the digital camera, you have to ready the camera. Have a look at the Nikon D200 quick start guide and perform the following steps:

• Charge the battery.

• Insert the battery.

• Choose a language and set the clock.

• Attach the lens.

• Insert the memory card.

• Format the memory card.

Be sure to do this at least 2 hours before you want to use the camera, as charging an exhausted battery takes some time.

7.2 Setup before scanning

The first time you want to use the camera for scanning, you have to change certain settings of the camera. It is recommended to check these settings each time before you use the camera again.

Please have a look at the Nikon D200 Quick Start Guide to see how to perform the following steps:

Page 30

User’s manual FARO Laser Scanner LS 30

• Set the shooting mode to S

• Select M mode

• Set image quality to RAW

• Set white balancing to K

• Rotate the focus-mode selector to M

Have a look at The Nikon Guide to Digital Photography with the D200 to perform the following:

• Set the USB option to PTP.

Page 31

User’s manual FARO Laser Scanner LS 31

The following steps have to be done each time before scanning:

• Select an appropriate white balance temperature. Auto white balance is not recommended, as your panoramic environment probably contains a lot of different light sources which would cause a different white balance on each picture. Make some test images to check the white balance setting.

• Turn the camera off and connect the USB cable to the camera.

Now prepare the scanner and hook up the camera:

• Put the camera mount on the mirror module of the scanner.

• Either use horizontal orientation of the camera or top orientation.

Page 32

User’s manual FARO Laser Scanner LS 32

• Adjust the focus manually to ∞ using the lens focusing ring.

• Connect the USB cable to the scanner.

• Turn the camera on.

7.3 Scanning with color

• Start FARO Record and connect to the scanner as usual.

• Open the camera tab of the scanner parameter dialog and adjust the camera

parameters according to chapter 6.3.1.9. Make sure that the correct camera mount and camera orientation is selected.

• If you are using the new non-parallax camera mount with the sliding mechanism, make sure that the camera is now in its parking position over the mirror module and the scanner is wound up.

Page 33

User’s manual FARO Laser Scanner LS 33

• The gear column may have some rotational degree of freedom. When tightening the fastener, please make sure that the gear column is at one of its end positions within this freedom.

• Start scanning by pressing The scanner will now first take an ordinary scan and will turn 180°. Then it will continue to turn to 360° and determine additional exposure settings. At the end of the full turn, it will calculate a balanced exposure setting.

• If you are using the new non-parallax camera mount with the sliding mechanism, you are now asked to move the camera into its operating position over the mirror itself, and to wind down the scanner. If you are using the new FARO carbon fibre tripod set as shown in the pictures wind down the scanner the whole distance of the gear column (20 centimeters). If you are using other tripods wind down the scanner for exactly 20 centimeters.

Page 34

User’s manual FARO Laser Scanner LS 34

Please make sure that the gear column is at the same end position in its rotational freedom as before.

• The scanner will now turn backwards and will stop several times to take a picture on each stop.

• The pictures are automatically transferred to the controlling computer and put into the scan file.

7.4 Applying the pictures to the scan

The scan points aren’t colorized automatically after the scan has been taken. This process has to be started manually.

The scanner based pictures are stored within the scan and can be seen in the structure view.

Fig.20 Scan with pictures

Select the command Apply Pictures in the context menu of the scan. This will first load the scan and all its pictures. Then it will remove any distortions from the pictures. Finally it will add the color information to the scan points. Please don’t forget to check the setting of Save modified scan points in the options and to save the scan afterwards, this is not done automatically.

If you want to treat every scan in your scan folder that way, you can select the command Apply Pictures in the context menu of the scan folder. In this case, the scans are saved automatically afterwards if you have the correct setting of Save modified scan points in the options.

8 Using FARO Record Mobile with a PDA

FARO Record mobile offers a web interface to control the scanner. In combination with WLAN and a PDA, this is a very comfortable way to operate the Laser Scanner LS. Please note that old scanners need a special software upgrade for FARO Record mobile.

As the scanner will now offer to different connection types (LAN and WLAN), a conflict may arise when both a laptop and a PDA are used at the time. In this case, the scanner is not operable with the PDA.

Please note: Although any web browser can be used on the PDA, some of them show problems with image manipulation like zooming. It is recommended to use Opera Mobile (

http://www.opera.com/) for smooth operation.

8.1 Setting up the WLAN connection

8.1.1 FARO LaserScanner LS

Attention: Use the blue data and power cable with the bend connector!

Plug the Fritz!WLAN USB stick into one of the USB ports of the scanner. Please note that you can only use the Fritz!WLAN USB stick to establish a WLAN connection to the scanner.

Fig.21 WLAN Stick in the USB port

The WLAN of the scanner is automatically configured to be in Adhoc mode with WEP encryption. The IP address and subnet mask of the WLAN connection are derived from the scanner’s ordinary LAN connection. In order to get the actual WLAN settings, you should use your laptop and the ordinary LAN connection. Start your favorite web browser on your laptop and connect to FARO Record mobile on the scanner by entering the LAN IP address. Make sure that no FARO Scene is currently connected to the scanner. You should now see the start page of FARO Record mobile.

Page 36

User’s manual FARO Laser Scanner LS 36

Fig.22 Start page of FARO Record mobile

Follow the link System Information, and you will see the WLAN connection settings.

Fig.23 System information of the scanner’s networks

You’ll need the WLAN IP address, the WLAN subnet mask, and the WEP key when setting up your PDA.

8.1.2 PDA

Please consult the user manual of your PDA on how to setup its WLAN connection. In general, in order to configure the WLAN connection, you have to open the

configuration dialog of the network adapters: Start  Settings  Network Cards

Page 37

User’s manual FARO Laser Scanner LS 37

Fig.24 Select WLAN adapter

Select the WLAN adapter, and enter a WLAN IP address and WLAN subnet mask. The WLAN IP address should be compatible with the one of the scanner (see chapter 8.1.1). If you like, you can take the WLAN IP address of the scanner and simply change the last number. For example, if the scanner has 172.16.15.97, you can enter 172.16.15.90 here. The WLAN subnet mask should be the same as the one of the Laser Scanner LS

Fig.25 WLAN IP address

On some PDA’s, you may have to explicitly switch on the WLAN connection (for example by clicking on the earth globe as seen in the lower right corner in the following figure). In addition, some PDA’s may require a reboot after the WLAN address has been changed. Most often, this reboot is performed by pressing a tiny button with a pencil.

Page 38

Fig.26 Switch WLAN connection on

It should then show you the available network of the scanner, to which you can connect to. You will then be asked for the security key, which you have retrieved before (see chapter 8.1.1).

8.2 Setting up Opera

When using Opera it is recommended to change some default settings of Opera as described below. Open Opera on your PDA, select Menu, then Display, and activate Desktop. It is also recommended to change the orientation to the Landscape. Please also notice the option Full Screen which you can activate to maximize the usable screen area for FARO Record mobile. To return from Full Screen hold the pen down on the screen until a context menu appears and click on Full Screen again.
