Installation and Setup
Installation and Setup
This guide takes you through using VIOSO autoalignment software with an IDS camera for aligning a
flat screen projection, exporting alignment data as MPCDI and importing it into Delta. Whilst the
worked example here is a flat-screen, VIOSO autoalignment is available for any projection.
Requirements
7thSense software: DeltaServer / DeltaGUI 2.6
VIOSO software: Setup_VIOSO_Integrate_x64.exe
IDS camera with driver v4.82.2: uEye64_48202_WHQL.exe
Power over Ethernet (PoE) injector
Camera Mounting
Mount the IDS camera on a sturdy tripod.
For a dome, the (fisheye) lens needs to be facing normal to the pole of the dome, close to the dome
spring line, so that it can see the whole display – but as little more as possible.
Unwanted light should be minimised to achieve best light contrast, and kept constant.
Note that the tripod thread was on the top of the camera used for this guide, so the image is flipped.
Connect the camera to the PoE injector and the PoE injector to the network and power.
Installation on Control PC
1. Install VIOSO Calibrator.
2. Install IDS camera driver (uEye).
3. Install DeltaGUI.
IDS Camera Driver Configuration
1. Run IDS Camera Manager.

Installation and Setup
2. Select the NIC that is connected to the same network as the PoE camera.
3. Select the camera from the Camera list.
4. Select Automatic ETH Configuration.
5. Close the software.
IDS Camera Driver Testing
1. Test the picture by running uEye Cockpit.
2. Select Optimal colours.
3. Click on the play icon with the camera in the top-right corner (under the ‘File’ menu).
Note that the image may be rotated 180 degrees if the camera is mounted inverted, which can be
fixed by clicking on the wrench icon, selecting the Size tab, and mirroring the Left/right and
Up/down under the Format section.
4. Adjust the zoom and iris settings by loosening the screw locks counter-/anti-clockwise,
positioning them appropriately using the camera feed for preview, and tightening to lock them
into place.
5. Close all windows when testing is complete.
VIOSO Integrate
A. Select Displays and Camera
1. Launch VIOSO Integrate from the desktop.
2. On opening, you may see a prompt stating ‘Overlap detected’. Click Yes.
3. Select Calibrate to begin.

4. Select single client calibration and then you should see a window like this:
5. Select ‘display split’.

6. Set the number of vertical parts/horizontal parts to match the Eyefinity or Mosaic group and
apply:

7. Select all displays for the calibration and the screen type for Setup method:
8. Set the projector arrangement to match the arrangement on screen.
9. Set any Extended Options as desired, or use defaults.

11. Adjust the camera zoom under the Format menu to zoom into the screen shape, which reduces
processing time:

12. Draw a mask around the screen area. Single click to set the first point, double click to end a line
making sure to overlap your lines:

13. Fill the unwanted region of the image with the paint bucket tool and optionally save the mask:
14. Select Next

B. Geometric Correction
1. If asked which set of geometric correction data source to use, select Method: ‘Perform new scan’.

2. If the initial result does not yield bright green circles, press back to adjust the noise filter,
otherwise, proceed to step 5, ‘Adjust geometry scan inspection options’.

15

3. Adjust the threshold and thickness until you have thin, distinct lines across your entire projected
surface and click Next.

4. Adjust the sliders to change the circle size and spacing until you have distinct green circles, then
select Next.

5. Adjust geometry scan inspection options.
a. You can control extrapolation and geometry fitting.
b. If you change something, press recalibrate and check on screen.
c. Press ‘Show Info’ to get extended information about measurements.
d. You can adjust strictness on outliers.
e. Select ‘Full Polynomial’ (standard extrapolation method / preferred) if all points are on a
simple geometry, like sphere or cylinder.
f. Select ‘Partial Polynomial’ (alternative extrapolation method / use geometry does not match
in overlaps – adds unwanted waviness on corners) for arbitrary shapes (but still the shape
needs to be continuous [no corners]).
g. Number of points that must be extrapolated (-1 = whole display). Check if needed area is
covered by projection.

h. Change ‘Surface curvature’ for extreme screens.
i. Check ‘Intense overshooting of projector’ if a big part of the projection is not displayed on the
screen.
j. Uncheck ‘Optimization of mesh’ if the shape does not match the real screen.
k. You can use cropping masks to cut parts of the projectors and change blending zones.
l. Load your own test image.
m. Save calibration for further use or for debugging send to VIOSO.
6. Once the calibration is complete for the first display, click Next and repeat stage 3. Geometric
Correction for remaining displays.
7. Adjust the points – adding more as necessary – to define your screen bounds.
C. Export MPCDI Data
1. In the Calibrator software, select File > Export Mapping.
2. Select the target display (not the individual displays) and your desired format from the dropdown.
3. Tick ‘Individual split export’.
4. Tick ‘Virtual content rects’ in case you want to let VIOSO do the slicing; you’ll find a ~_def.txt
containing optimal content size and scanouts.
5. Set your file name. To change the folder, use the ‘Browse’ button.
6. Click ‘Export’.
Load Mapping into Delta Media Server
Delta incorporates VIOSO autoalignment data as MPCDI (Multiple Projection Common Data
Interchange v.2, 2013). This common standard for exchange of channel blends and warps and
projector positional data as defined by VESA (see VESA Standards).

19

Load Mapping into Delta Media Server
On Delta Media servers, MPCDI files are stored in the standard folder for Delta: C:
\AutoAlignment\MPCDI.
Copy the alignment data to this folder. The size of these files and the corresponding load that they
add to Delta is a function of their resolution.
Note the file-naming standard, using the prefixes AlphaMap~ for the blend images, and
GeometryWarpFile~ for the warps. The matching suffixes after a hyphen (in this example, g 1 to g 4)
is what you will see in DeltaGUI. These are the MPCDI regions (Delta: channels). You need to know
how these regions correspond to your Delta channel numbers so that you can match them up.
