Congratulations on your purchase of the latest
professional 3D scanner Calibry!
The device uses the latest developments in structured
light scanning and even enables the capture of complex
surfaces.
This guide provides information on how to install and
use Calibry software, how to operate the scanner, and
recommendations for the scanning process itself.
When using the device, keep in mind that the 3Dscanner
is a high-precision optical device that requires careful
attention. Careful use and compliance with the rules of
use will ensure a long life for the scanner.

Connect the scanner to a computer with the Calibry Nest
software installed.
•Strictly follow the connection sequence. Make all connections when
the power supply unit is disconnected. Connect the power supply unit
when all other connections have been made. Otherwise, the equipment
may be damaged, and this case will not be covered under the warranty.
When the scanner is powered on, it turns on automatically.
•When you rst connect the scanner to the computer, we recommend
that you connect the computer to the Internet. In this case, the software
will automatically download the scanner calibration le, and the scanner
will be ready for use. Otherwise, you can manually download the calibra-
tion le. The calibration le can be requested from the supplier of the
scanner.

carried out will be placed
on the main screen. The
scans are sorted by crea-

The preview mode allows you to select the correct scan angle, to determine
the optimal distance, to assess the nature of the surface, to set up the scan pa-
rameters, and to determine the adequacy of the number of markers applied.
In the preview mode, additional buttons appear on the screen allowing
you to adjust the scan settings.

ture, respectively. Depending on the mode selected data visualization on

Texture frames rate
This parameter determines the rate of recording frames by the texture
camera, necessary for building a textured model. For example, if the value
of this parameter is 10, then every 10th frame taken during shooting is
used to scan texture.
Recommended value for shooting with texture 20.
Decrease the setting value to increase the number of texture frames in the
project. In some cases, this can improve texturing.
Increase the setting value to decrease the number of texture frames in the
project. In some cases, this can improve texturing as well. And in any case,
this will reduce the project volume and post-processing time.
The parameter does not affect tracking by markers and texture.

Screen frames rate
This parameter determines the frame update rates on the scanner screen
during preview and scan modes. Increase the setting value to improve the
picture quality displayed on the scanner screen. If increasing the value slows
down the scanning, decrease it back.

Texture brightness
This parameter determines the frame texture brightness.
If you change the value of this parameter, the image from the texture cam-
era is displayed on the scanner screen, so you can visually assess the texture
quality in advance.
Set the parameter value so that the texture is displayed in the best quali-
ty. Before scanning, in preview mode analyze the texture image in different
parts of the scanned surface. In case of glare, the corresponding surface are-
as will be tinted in red.

Set this parameter to one of the following values.
To select the maximum, average or minimum projector capacity, respec-
tively.
As a rule, the maximum capacity mode is used to scan dark objects. The
minimum capacity mode is recommended for scanning shiny objects. The
default mode is average capacity.
Set this parameter to one of the following values.
To select the maximum, average or minimum texture ash capacity, respec-

The setting is available in geometry tracking mode only.

Scanning in geometry tracking mode
Scanner
operation
During scanning, it is important to keep the
optimal distance between the scanner and
the object being scanned. For convenience,
and depending on the distance, the scanned
surface is tinted with a certain colour. The colour
from the middle part of the spectrum (green)
indicates that the scanning distance is close to
optimal. If the scanning distance is too small, the
object is tinted with the colours from the lower
part of the spectrum (yellow – orange − red). If
the scanning distance is too large, the object
is tinted with the colours from the upper part
of the spectrum (light blue – blue − purple). It
is recommended that as much of the object as
possible is tinted with the green colour during
scanning.

Scanning in marker tracking mode
Scanner
operation
When scanning by markers, it is important
that each frame shot contains at least 3 mark-
ers (this is a critical value), optimally at least
5 markers. The indicator changing the colour
depending on the xed number of markers in
the last frame helps to control the number of
markers:
• If it is 4 or less, the indicator is red (critically)
• If it is 5, the indicator is yellow (warning)
• If it is more than 5, the indicator is green
(good)
If there are not enough markers in the frame
(less than three), the scanning will automatically
stop, and the scanner will return to the preview
mode. Then you should nd a more comforta-
ble position to scan and start again.
Number of markers in
the frame
Scan in marker tracking mode if the object does not have characteristic fea-
tures of geometry or texture, as well as if these features make up a periodical-
ly repeating pattern.
Sometimes, the object you are scanning is small enough that it ts comfortably into a single
frame. In this case, you can place the markers around the object (on the table or the oor),
instead of adding them directly onto the object.

Scan in texture tracking mode if the object has characteristic texture features,
while scanning in geometry or marker tracking mode is not possible.
When scanning in texture tracking mode, a textured image is displayed on
the scanner screen. To maintain the correct scanning distance, use the scale
on the left. If the correct distance to the object is not maintained during scan-
ning, the image on the screen will «crumble». Red areas on the scanned surface
indicate glare. If they appear, decrease the value of the Texture Brightness pa-
rameter and / or change the scanning angle.

Calibration of the scanner
Scanner
operation
The Calibry scanner is an accurate measuring tool that is factory calibrated.
In order to ensure high scanning accuracy, Calibry has the option of custom
calibration.
A simple test is sufcient to detect if the scanner needs to be calibrated. In
geometry tracking mode, try to «look» at a at object, such as a oor or a wall,
by means of the scanner. The atness should be seen without «holes» and
distortions.
However, even with the correct restoration of the atness, it is recommended
to calibrate the scanner from time to time. The frequency of calibration de-
pends on the intensity of use of the scanner. For daily use, it is recommended
to calibrate the scanner twice a week.

Calibration of the scanner
Scanner
operation
To prepare for calibration, assemble the calibration stand.
For easy assembly, it is recommended to screw the top panel of the stand
to the scanner in advance.
Place the scanner about 50 cm away from the calibration stand.
