12. Auto-Aligner

For the closest match of virtual graphics to real world camera the StarTracker o󰍒ers through-

lens calibration to tweak o󰍒sets that were set during the mapping and calibration processes.

You will need to have the ST sensor unit rigidly mounted on the studio camera, have performed

the mapping and O,X,Y map alignment and ST sensor calibration steps.

12.1 Auto-Aligner Operation

Before commencing with the Auto-Aligner makes sure you have measured and entered your TP

Right, TP Down and TP Forward accurately (see camera o󰍒sets).

The Auto-Alignment process will involve marking 3 known reference points in the studio and

gathering several observations of them by looking at them through the centre of the studio

camera lens. From this the system will automatically tweak the map and camera o󰍒sets to try to

give tracking data that best matches these viewpoints.

Note: This calibration process cannot tweak the “TP Forward” or “Roll O󰍎set” values,

as set in the O󰍎sets menu.

To start, measure and mark 3 points on the studio 󰍔oor whose 3D positions relative to the map

origin (0 position) you can measure accurately in X, Y and H (height). In the below image the red

marker is our zero point. Ideally the marked points should be in an area of the studio where the

talent will be later and where the cameras are mostly looking at.

If you have an Auto-Align kit, assemble it accordingly.

If you have an LED volume with 󰍔oor tiles you can use the tiles as reference. See image below:
