is not synced properly to the virtual set, you may see: - only one graphic image rather than two
overlapping graphics
one graphic image become “solid” for a moment
graphics “swap places” or move around
unstable 󰍔ickering or brief jumps in the graphics
This shows there is a problem in the genlock or synchronisation rather than a tracking quality
problem.
16.3 Mismatching Graphics
General Causes:
Incorrect or unwanted o󰍎sets in the StarTracker or virtual set software.:
Camera-centric o󰍒sets (modify the camera position)
Map-centric o󰍒sets (modify the map position)
Object-centric o󰍒sets (modify the position of a rendered object)
Lens:
Lens󰍓le - distortion, centre o󰍒sets, nodal o󰍒sets, 󰍓eld of view
Encoders (gearwheels loose or not meshing properly)
Direction of encoders (can be reversed in StarTracker (Data –> Lens Data)
If you zoom in and your graphics get smaller Zoom direction needs to be reversed
If you zoom out and your graphics get bigger Zoom direction needs to be reversed
Focus is harder to identify. Because of lens breathing (changing of FoV when focusing) you
can use the same method as with Zoom, watching the graphics get smaller or bigger in
correspondents to the background video when changing the focus. If it doesn’t match,
Focus direction needs to be reversed.
Lens limits (ranges) not set or incorrect
Macro-mode switch inadvertently toggled
Non-o󰍒set tracking issues - Local map position or height error (i.e., only in certain places)
Scaling of map not quite correct - Real-world mismatches Curved studio 󰍔oor assumed to be
󰍔at, especially where O,X,Y was dropped Loose screws or sensor mounting bracket unmounted
and remounted
Generic through-camera tool 1. Choose a reference point you know the coordinates of to
look at, e.g., the origin: - In O󰍒sets→ Verify click on “Ref pt” so it says “Centre”, then enter the
