Installing software and drivers
Connect USB disk with RangeVision logo to your PC and launch RangeVision ScanCenter setup

6
Following the tips, choose the language, type and the path of installation. After copying the files
install drivers and graphic libraries, which are necessary for correct functioning of RangeVision 3D scanner.
After the setup on the desktop should appear RangeVision programs: ScanCenter, ScanMerge and IDS
Camera Manager.
Setting up your computer for the work with the scanner
For correct functioning of 3D scanner it is necessary to adjust your computer. This procedure is executed
once before the first use of the scanner.
Connecting projector
After connection the projector will be displayed in the system.
If the computer has several video output you should define the needed one.

7
Note
If the second monitor (projector) wasn`t recognized by the system –check cable
connection and restart the computer.
You can also connect the cable to computer with switched on projector if it was off.
●After clicking by the right button on the desktop, choose screen resolution
●Choose in the list –Screen , or by clicking number 2, 2nd monitor.
●Choose Extend these screens choose in the popup Several screens.
UAC Setting
For more comfortable work with scanning program it`s advisable to change account settings.
For this purpose enter Control panel- User accounts- Change user accounts control settings.
Put the slider maximally down and save the changes.

8
Connecting cameras
After installing camera drivers at the desktop of your computer there should appear IDS camera
Manager. Do not connect cameras before installing drivers! Connect cameras to USB-ports of the computer
and launch IDS Camera Manager.
The application will show connected cameras and their state. Both cameras must be available. If
one of the cameras is busy, check any third-party software that can make use of it, for example, Skype.
Switch off the programs, using web-cameras and check the accessibility of cameras to IDS.
Go to the menu "Additional functions" and put check-mark in front of "Idle state": Disable. As it`s
shown on the picture.

9
Configuring computer parameters
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 mode
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.

10
Enter Device Manager in control panel properties and remember the name of COM-port, used by the
table. After starting ScanCenter (look below) in scanner configuration settings (Adjustment –Configuration –
Rotary table) write the port number in the field Device number. Choose the model of the table - TS-12 (
since 01.2016) or Default
If the table wasn`t successfully connected, during scanning the error will occur. Check the connection of
the turn table, driver setup and correctness of COM-port number in
scanner configuration settings.
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.

11
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.
Scanner settings
Setup Wizard
To configure Smart before scanning, launch Setup wizard. It step by step describes all actions,
necessary to configure the scanner. In addition, please carefully read this chapter.

12
Select the scanning zone, which best suits for scanning your object, and perform all actions, described
in each step of the Wizard.
Scanning zones
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.
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.

13
Start RаngeVisiоn SсаnCenter
Run Rangevision ScanCenter. You may need administrator rights to do this. Turned on projector and
cameras must be connected in advance.
At the first start you will encounter a window, where you have to select the configuration settings of
the scanner. After starting the program this menu item is available in Adjustment –Configuration.
In the tab Projector select Acer smart. On the cameras tab you should select model XS (determined
automatically).
If all settings are correct, after starting the program will appear a window with a warning regarding the
warm-up cameras. Caution! Warming-up cameras is required for the stable operation of the scanner.
Otherwise, errors can occur during the scanning and calibration procedures.
The warm-up time depends on the temperature in the room, the approximate working temperature of
cameras is about 50°C. After warm-up you should see an image from the cameras. The current
temperature of the cameras after the warm-up is displayed in the Toolbar.
Check the correctness of cameras positioning, for example, by covering one of them with your hand. If
the image from one camera belongs to the other one or is reversed, go to the Adjustment - Configuration -
Cameras tab and select Swap cameras.

14
Calibration
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. The
approximate distance to fields is specified in the table.
Scanning zone, №

Distance, cm
65-70
37-40
15-18
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).
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. Setting up is carried by scrolling a wheel
next to the projector lens.

15
As the cameras are not focused yet, the image may be blurred. Evaluate the adjusted sharpness visually
by the calibration plate.
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
back side 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.

16
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.
Orientation
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
●Developer solution ПС-33
There are also some difficulties when you are scanning objects with sharp edges, deep grooves or holes,
thin wall objects. Problems can also be caused by objects that contain large contrast areas (for example,
black lettering on white paper). 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
