Lens Profiling
Lens Profiling is the determination and documenting of the characteristics of a lens.
This section is a step-by-step guide for the physical and software setup that is necessary to enable profiling, and also the profiling process itself.
How Precise Should the Profiling Be?
For XR production with an LED wall, a very precise profiling of the lens and also the tracker is usually required. Such profiling might be a lengthy and highly iterative process that requires expertise of tracking systems and lenses in general. This is true especially for certain lenses which have complicated and non-linear multi-factor distortion behavior.
However, for green screen virtual studio, or standard augmented reality scenarios, even a quick and coarse profiling would be sufficient most of the time.
