1. Introduction
Thank you for choosing IT3D SCAN ONE 3D scanner!
Please read this manual before using IT3D SCAN ONE 3D scanner. Here are described
the procedures for preparing the scanner, installing the required drivers, calibration
procedure, scanning procedure, and tips for acquiring high-quality three-dimensional
object model.
Information may be amended from time to time. These changes will be inserted into the
new versions of the manual, or in the additional documents and publications.
▪Do not expose the scanner to liquids.
▪Do not use liquid cleaners or aerosol cleaners.
▪Do not store or use the scanner in dusty or humid environments.
▪Do not expose the scanner and its components to contamination, shock or
drops.
▪Do not connect power to a faulty wall outlet.
▪Do not aim the scanner at people and animals in order to avoid directing the
bright projectors light at the eyes.
▪Patterns and holes are provided for ventilation of the scanner to ensure its
reliable operation and to prevent overheating. Do not block or cover the
openings.

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.

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.

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.
