It's forbidden to use USB hub and connect cameras to one port!
The scanner can't send data correctly with only one USB!

Connecting the turn table
Before scanning on turn table it`s necessary to install table driver, to plug it in and to
connect the table with the computer via USB-cable.
Scanner may be equipped with different types of turn tables, with additional power
supply or without it, and depending on the controller, the name of the connected device
can be different, for example Silicon Labs, Arduino Uno, Rangevision Table and so on.
For the correct operation of Rаngevisiоn 3D scanner you will need to setup your
computer. This procedure is performed once before the first use of the scanner.

For checking efficiency of the table, turn it for a little angle. On the menu choose
Adjustment Table calibration. Enter the angle number and press Turn. The table must
rotate clockwise, viewed from above. If the table rotates in another direction, change
the parameter - Change the direction in configuration settings.
Apart from other modes, before using turn table for scanning it`s necessary to
evaluate its axis (to perform table calibration). It`s done in order that the scanner could
acquire positioning of table axis for automatical fragment registration. Additional
calibration of table is necessary, if during scanning the reciprocal positioning of the
table and the scanner changed.
In order to avoid problems with scanner functioning it`s necessary to switch off
screensaver and sleeping mode.
Click by the right mouse button on the desktop choose Personalization
Screensaver, switch off the screensaver and transition of the computer to sleeping

For normal operation, scanner requires warming up. If the cameras aren’t warmed
upenough, the program at startup will notify you about it.
After warming up the value of the current temperature of the cameras is showing in
the Toolbar.
Check that the right corresponds to the right camera image, and the left
camera - the left image. The right camera - one that is on your right, if you
stand to face scanning object.
If the cameras are swapped, change the state of the parameter Swap
cameras on the Camera tab in the configuration dialog box
Check the connection of cables, power supply, and then click Retry. If you are sure
that all the components of the scanner are connected correctly and the connection
error persists, click Skip to select your scanner settings manually. If necessary, contact
the technical support of your reseller. If the scanner is not connected intentially and
none of the components can be found, after clicking Skip ScanCenter will run
immediately without manual selection of equipment. In the future, you can select
hardware on Settings Configuration.
In the case if all the settings are correct, after starting the program, you should see
the image from the cameras in the main application window, and the projector will start
projecting cross.

Configuration Wizard
To configure Smart before scanning, launch Configuration wizard. It step by step
describes all actions, necessary to configure the scanner. In addition, please carefully
read this chapter.
12
Scanning zones
Before beginning the configuration, select the desired scan area (zone), depending
on the object scanned.
RаngeVisiоn Smart scanner can be
configured to 3 scaning zones. By
changing the distance between the
cameras and the follow-up calibration,
changes the size of the scanning zone.
For each scanner area a separate
calibration plate is used. Scan zone № 3
has higher surface detail, but obtaining
a model of a large object will require a
greater number of scanned fragments.
On scan zone № 1 one capture results a
model of a large fragment of the object
surface, but with lower detail. The
optimal choice of scaning zone is when
an object is placed in the scan area and
is comparable in size to the calibration
plate. Evaluate the size of the object and
select a suitable scanning zone.

Calibration field size
Take the necessary calibration to configure the scanner to the selected scan area.
Make sure that the scan area is included in the packaging of your scanner.
The exact size is written on the label on the reverse of the calibration plate. Enter
this value in the Configuration Wizard or select from the drop-down list of previously
entered values.

Initial setup of cameras
Disconnect USB cable from the cameras, and using a hex key loosen the screws of
cameras. Move the cameras, aligning the marks on their housing with the marks on
housing of the scanner. On the smallest scan zone №3 the cameras are as close as
possible, on scan zone №2 they correspond to the medium position, and scan zone №
1 - furthest. Please note, in order to set up the scanner to scan zone №1, first you must
perform the calibration for the zone №2, therefore, the initial position cameras should
be 2. After installation of cameras tighten cap screws and connect USB cables to the
cameras. In the figure below the position of cameras corresponds to the scan
zone №3.

Move the plate or the scanner so that the view of the plate from both cameras is
symmetrical, keeping the distance from the scanner to the plate unchanged. Turn on
the mode Lines and stripes and adjust the focus of the projector, so that the lines are
as sharp as possible. Set up the focus is by scrolling a wheel next to the projector lens.
As the cameras are not focused yet, the image may be blurred. Evaluate the
adjusted sharpness visually by the calibration plate.
Install the plate in such a way as to ensure that the blue markings on the view from
one of the cameras has matched with furthest marks on the calibration plate, as shown
in the figure below. When placing plate on the stand, pay attention that top part of the
plate has black triangles. Move the plate closer to or further away from the scanner,
until the image from the camera will not display that the vertical lines of grid cross the
furthest marks on the plate. On the figure the working distance is determined by the
right-hand camera. The distance from the scanner cameras to the plate shall be
maintained in this position during calibration and scanning (hereinafter - working
distance).

Take the calibration plate in accordance with the selected scanning zone: large for
scanning zones № 1,2, small for scanning zone № 3. Install the plate on the magnetic
stand in front of the scanner.

Calibration
16
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
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, Orientation (short calibration) and
Calibration of turn table (finding the table axis).
Full calibration is used if:
The lenses of the cameras need to be reconfigured (for example, if you change
the scanning area)
If you suspect that scanning accuracy got worse
After transporting the scanning complex
Orientation is used:
If you suspect that the camera moved due to unreliable mounting
If you want to check the accuracy of performed calibration
Before the work with the scanner (recommended)
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 rotary table)
Calibration of rotary table is described in the section Scanning on rotary table.
Run the Full calibration on the Settings tab.
When calibrating the scanner makes snapshots of the calibration plate in 11
different positions. Calibration field is pre-measured with high accuracy. Size of
calibration plate is specified in the table on the backside of each plate. This option
should be specified in advance before the first calibration in Edit plates.

Be careful when selecting the plate, specifying its size, and during calibration! When
the calibration is incorrect, there may be problems when scanning and you will receive
model with distorted size.
Specify the added plate in the list Select plate. When making a selection, settings of
Lenses will automatically be changed. RаngeVisiоn Smart always has focal length of
the lenses of 4.3 mm.
Calibration is performed without illumination with natural light, when you start the
calibration dialogue, the mode "Black light" is activated. Using the slider in the toolbar
increase the value of exposure of the cameras. If the image of the plate is still dark,
increase the brightness of the external lighting.
After this, click Capture. Camera will focus on the calibration plate. Visually inspect
the sharpness of the cameras after focusing.
If the cameras are focused, you will get a snapshot of the plate in the first position.
At the calibration during shooting both the scanner and the calibration plate must be
fixed relative to each other! To make snapshots in other positions, set the plate
according to the instructions in the program and a schematic representation. Do not
change the distance to calibration field, if this is not stated in the prompt (positions 10
and 11). To set the plate to the desired position, change the position and tilt of
magnetic stand, or the position of the scanner on a tripod.
After the last snapshot will be performed an analysis of the data for calibration.
17

Final precision is 0.** shows the calibration accuracy. Memorize the measured
value and close the calibration menu.
Short Calibration function (orientation) is used to test the accuracy of calibration.
This is a simplified version of full calibration, the calculation occurs after the one
capture of calibration plate in the initial position (at the working distance from the
scanner). Orientation is also used to configure to the scan area № 1.
After performing the Full calibration before the scan, perform Orientation. Measured
value of Final precision must be less than 0.1 pix. If the value has proved to be greater,
perform calibration again, taking care of warm-up of the cameras, the position of
calibration plate and the size of the plate specified in the program.
Example 1: A complete calibration result was final precision 0.095 pix, after
Orienting - 0.076 pix. Scanner calibration has been performed.
Example 2: A complete calibration result was final precision 0.124 pix, after
Orienting - 0.11 pix. Scanner calibration has not been performed, it is necessary to
calibrate again.
To calibrate for the scanning zone №1, first you must perform calibration for
scanning zone №2. Than you need to close ScanCenter, move cameras to positions for
scanning zone №1 (to do this you will have to temporarily disconnect USB cables) and
again launch ScanCenter.
Letting cameras to warm up, install calibration plate on the distance 65 - 70 cm
from the scanner and perform Orientation. Turn on Stripes and Lines and check the
projector focus.
18

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.
After calibration the calibration plate should be put inside the carrying case in order
to avoid the damage or contamination!

Scanning
Requirements for the scanned object
The scanner analyses structured light reflected from the surface of the object,
therefore, scanning should be carried out in premises without direct sunlight, as well as
free of dust and vibration. For the same reason scanning of the following objects is not
possible or is too difficult:
too dark and black objects
transparent objects
mirrors
flecking and glossy objects
fur
To work with such objects it is recommended to process them with special aerosol
products prior scanning, which leave a very thin coat of white powder on the object
after drying. HELLING Developer solution U89, Sherwin D-100.
There are also some difficulties when you are scanning objects with sharp edges,
deep grooves or holes, thin wall objects. Objects that contain large contrast areas (for
example, black lettering on white paper) can also cause problems. Geometrical
distortion may appear in places with strong contrast.
Scanning principle and methods
If you're shooting a single fragment (scan) - you get a three-dimensional model of
the object surface. To create a full object model you need to obtain surfaces of the
object, that together entirety replicate the form of the object, i.e. scan the object from
different angles.
Obtained fragments are combined in the special software by the surface geometry,
hence there is another requirement - the object must be rigid and do not change its
shape during the entire scanning procedure. Otherwise, the geometry of the same area
of the object surface of different scans may be different, and it will be impossible to
unite the pieces into a coherent whole.
In RangeVision 3D scanner there are 3 scan options available, which are different, in
the first place, by the fragment alignment method:
Scanning without markers
Scanning with markers (marks)
Scanning on the turn table (optional, not included in the standard kit)
