5.3 FUSION calibrator – Calibration View
When all FUSION processing system units are added to the project in the Device View, 
switch FUSION Calibrator to “Calibration View”. This is done by clicking the “Calibration 
View” button in the top-left corner. Clicking the same button in Calibration View mode will 
bring you back to Device View. See Figure 5-10.

5.3.2 Selecting/deselecting FUSION processing units
The FUSION Navigator is a window used to select multi image processing system units in a 
project, Figure 5-12. In this window, FUSION units can be selected or deselected either by 
clicking on them or using the assigned short cut key combination.

5.3.3 Using the Calibration Panel Toolbar (CPT)
The calibration panel has a set of tools on the left hand side of the wi\
ndow. This toolbar can 
be shown with or without help texts, Figure 5-14. Calibration Panel Toolbar, without and with 
help texts.

The Calibration Panel Toolbar has these main functions:
•	Zoom. Scale the work area in the calibration panel.
•	Image Orientation. Change the orientation of the calibration panel to ma\
tch the physical orientation of the projector. 
•	Set Colors. Set the color for background, lines, control points and internal test patterns, see Figure 5-15.

•	Bezier Fixed Length/Angle. Specify the bezier guide point behaviour. Off allow adjust-ment of both length and angle. Fixed length allows the user to change an\
gle, but not the length. Fixed 1/3 length will fix the length to 1/3 when the control point is moved. Fixed angle allow the user to change the length while the angle is fixed.

6 Geometry correction
Image Geometry Correction (often referred to as Image Warping) is the process of digitally 
manipulating image data so that the image’s projection precisely matches a specific 
projection surface or shape. Image Geometry Correction compensates for the distortion 
created by off-axis projection or screen placement or non-flat screen surfaces by applying a 
compensating inverse distortion to the image in the digital domain. Usua\
lly, Image Geometry 
Correction is applied...

6.2 Warping user interface
To apply warping to an image, select “Warp” from the left hand toolbar. The window in Figure 
6-1 will appear.
 
Figure 6-1.  Warping algorithm setup
Algorithms can be added or removed. If the perspective transform is added first, Mesh Warp 
Transform can be used in addition. If Mesh Warp Transform or Mesh Warp Bezier is added 
first, a combination of algorithms is not allowed.
In this window, grid size is also configured. For the control...

6.3 Scaling filters
Regardless of the warping algorithms selected, a scaling filter will be app\
lied. Scaling filters 
are configured using the Algorithm Setup window. Select the tab “Filter”, Figure 6-2, and 
select your desired filter. Four different scaling filters are supported: 
•	Lanczos, B-spline, C-spline, Linear

6.3.1 Lanczos filter
The Lanczos filter is using a 4x4 kernel. This filter is recommended for use with images that 
contains large amounts of...

6.4 Working with the perspective algorithm
To start working with the perspective algorithm, click the “Warp” icon, add the perspective 
algorithm and set grid size to 1x1. To map the geometry to the surface being projected on by 
dragging the control points with the mouse. Figure 6-3 shows basic usage of the Perspective 
algorithm.
