Software and Drivers
Open the USB included in the IT3D SCAN ONE case and access the 02. Drivers IT3D
SCAN ONE folder to install the files "01. Turntable Driver - CH341" and "02. Cameras
Driver - Toupcam (UA310CB)". Both drivers are necessary for the correct operation of
the turntable and the cameras.
Next, open the folder 03. IT3D SCAN ScanCenter NG software. In this folder, run the
ScanCenterNG.exe file of the software by copying it to the desired directory on the
computer.
The IT3D SCAN ScanCenter NG software will start with the image below, and is
immediately ready for use.
Setting up your computer for work
For the correct operation of IT3D SCAN ONE 3D scanner you will need to setup your
computer. This procedure is performed once before the first use of the scanner.
Connecting projector
First, connect the USB cable to power up the projector and then connect it to the HDMI-
port of your video card. After connecting the projector, it should be displayed in the
system. If the computer has several video outputs, define the one to be used.
If the second monitor (projector) is not defined by the system, check the cable
connections and restart the computer. Also, try to connect the cable to your
computer when the projector is on, if it was off earlier.

1. Right click on the desktop, select Screen resolution.
2. Make sure that the projector has been successfully recognized by the system
and that both connected screens are displayed.
Configuring computer parameters
To avoid a recurrence of the problems during the scanner operation, you must turn off
the screensaver and sleep mode.
Go to Screen Saver Settings menu and turn off the screen saver, disable turning off the
display and putting the computer in sleep mode.

Scanner assembly
1. Install the scanning module onto the tripod.
2. Connect USB cable to your PC.
3. Connect HDMI cable to your PC.
4. When using the turntable, connect it to the power source, then connect the USB cable
to your PC.
3. Calibrating the scanner
You need to perform calibration in order to ensure the work of the scanner after the
adjustment of lenses. Specifically for this purpose we use the calibration plate, which
is pre-measured with high accuracy. Scanning software analyses the image of the
plate, obtained from the cameras and compares it with the mathematical model,
marked by the algorithm.
There are 3 types of calibration: Full calibration, automatic calibration, fast calibration
(orientation) and Calibration of turntable (finding the table axis).
Full and automatic calibrations are used:
•before work with the scanner.
•after transporting the scanner.
Fast calibration is used:
•if you suspect that the camera moved due to unreliable mounting.
•if you want to check the accuracy of performed calibration.

9
Calibration of rotary table is performed:
•in case of any change in the position of the rotary table to the scanner (when
scanning on the turntable).
Calibration of rotary table is described in the Scanning on the turntable section.
Calibration plate
Calibration plate is a special plate with markers, the distance between which is
measured with high accuracy. It is used for setting up a scanner and its calibration.
Full Calibration
The full calibration dialogue can be accessed from Calibration →Calibrate menu.
Calibration procedure:
1. In the drop-down list choose the correct calibration plate size, specified on the
back side of the plate, or add a new one.
Calibration should be performed in the same light, in which an object will be
scanned. If there is too much change of level in lighting conditions it is necessary
to recalibrate the system. It is not allowed to carry the calibration procedure on
direct sunlight.

10
It is possible that camera images in the software will be swapped or flipped from the
start. In this case, go to Hardware settings -> Cameras menu and use Rotate and Swap
cameras buttons to set the images in proper positions.
2. In accordance with the text prompt and symbol image install the calibration plate
in the desired position. The brightness of the images of calibration plate can be
adjusted with exposure slider. You should not allow very dark images or images
with excessive brightness areas. Press the Capture button. Original plate position
- the position at the working distance from the scanner (marking on the view from
cameras matches the markers on the plate), the cross is projected on the central
marker.
3. If the plate placement is incorrect, an error message will appear. Correct the
placement and repeat the step.
Make sure that the plate size specified in the software matches the actual plate
size written on its back side. Incorrect size may cause errors and geometric
distortions on meshes.
Camera image interpolation can be turned on and off in Hardware settings →
Cameras using Preview smoothing option. In some cases interpolation can make it
easier to determine if the image is sharp or not.
WARNING!

11
In case if not all marks are found on the image, you will also see the error message. It
may mean the following:
•Not all markers are visible on one of the snapshots.
•Not all markers are lit by the projector.
•Calibration plate is placed at large angle to the scanner.
•Plate is too close or too far from the scanner - the image is not sharp.
•The plate is damaged or dirty.
Correct all deficiencies and press Capture.
After all the necessary snapshots are taken, wait for the result of calibration procedure.
From now on the resulting accuracy of calibration will be specified on the home screen
in pixels. A good result is accuracy no worse (not higher) than 0.2 pix. If you get a higher
result, repeat the calibration, carefully checking the plates position and brightness. If it
is necessary, repeat calibration without blue light and filters.
Some advice on calibration:
•Do not change the distance from the center of the plate to the scanner when
turning the plate. The exception are only snapshots in positions 10 and 11.
•Do not rotate the plate at a very high angle. Ensure that all marks on the plate
are visible from both cameras, when you turn the table.
•Be careful with calibration plates! It is not permitted to contaminate or perform
any mechanical damage to the surface with the marks. After the use store the
plates in designated case.
•Before the calibration procedure ensure that cameras and cables are secure in
the designated position.
Calibration is carried out by the results of 11 snapshots. Carefully observe the
position of the plate during each capture! In some positions it will be necessary to
switch the bottom side of the plate.
Calibration result in pixels is not equal to scanner accuracy in millimetres!
WARNING!

12
Fast calibration (orientation)
The orientation can be started from the Calibration
window on the Start screen.
•Place the calibration plate at the working
distance to the scanner (the first calibration
position).
•Press the Capture button.
•Following the steps, make two more shots.
•After this, the accuracy of orientation will be
shown. It should be approximately equal to the
accuracy value of the last calibration.
If the accuracy during orienting starts to be very different from the original one, you
need to re-calibrate the equipment.
Example: The initial accuracy is 0.084, accuracy after orientation is 0.25. The value
exceeded 0.2, re-calibration is required.
When scanning large objects and moving the scanner frequently, the scanner
eventually may report that it cannot find markers. In such case you need to perform
fast calibration.
WARNING!
Orientation is carried out by the results of 3 snapshots. Orientation is done with the
same conditions as the last calibration. The corresponding controls in the dialog are
disabled.
After calibration or orientation, the calibration plate should be removed in order to
avoid the damage or contamination!
WARNING!

13
Automatic calibration
The automatic calibration can be started from the Calibration window on the Start
screen, but it is only accessible when turntable is connected and recognized by the
software.
Automatic calibration serves the same purpose as full calibration, but it is easier to
perform, because it uses turntable to shift the calibration plate between positions.
