The main objective of the Tracking Alignment Tool is to generate an Alignment Profile which captures the information about the relationship between the world coordinate from the tracking system to the world coordinate within SP.
Prerequisites
- At least one calibration screen or by using a more complex wall, a multiscreen in real life and in SP.
- A supported Tracking system data into SP
- Media input with the camera feed into SP.
- A camera object with a Lens Profile or an incoming camera tracking protocol which includes all intrinsic values.
Setup
If you have all the components ready as mentioned in the prerequisites section, you can set up the project to be ready for the Tracking Alignment.
- Under the camera object, add the map input for the tracking system and ensure that data is coming in correct for each of the components. (position, rotation, zoom, focus, etc)
- Under the camera object – Lens Profile, please link the correct Lens Profile object.
- Under the camera object – Tools, add a Calibration – Tracking Alignment.
There are different Calibration modes available depending on the situation with the tracking system and the setup.
| Name | Description |
|---|---|
| Tracking | This mode is mainly used for a camera that can be tracked as it moves to different locations in the venue |
| Nodal Origin | This mode is only used when lens needs to be swapped from the camera body and the nodal origin has been shifted slightly |
| Rotation Only | This mode is mainly used for a camera that is on a tripod / pedestal and would only be rotating on top of a fixed location |
| Pan Tilt Head | This mode is mainly used for Pan Tilt Head like PTZ cameras only. |
Once the correct mode is chosen for the setup that you have, can click on the “Image Calibration” button to open up the Image Calibration Wizard
Start Capturing
To capture an image click on the icon: 
Once images have been captured, you can click on the observation button to see what images have been saved.
Move the camera around within the desired tracking zone on all axis and capture more images.
If you are not happy with some of the images that have been captured, you can delete the image by highlighting the image and pressing “del”; or you can right click on an image and “disable the image”.
There are also options to “Reanalyze” images if you are reopening a previous project with captured images to relink the files, or the option to import images manually if these images were captured remotely.
Run Calibration
If sufficient images have been captured and you are happy with them, press the 
icon to run the calibration process.
After the calibration is completed, an Alignment Profile would be generated, applied to the camera, and the camera should be repositioned with SP to the appropriate location relative to the calibration screen.
You can open up the distortion viewer to double check if the alignment looks good or not.
If there is a region within the tracking zone that the alignment is not as good as you like, it is possible to capture more observations at this location and run the calibration again to improve the alignment.
