Bemerkung zur Veröffentlichung Abstract Light field cameras play an increasingly important

role in computer vision and optical metrology. However, due

to their complex design, their calibration is very difficult and

usually precisely adapted to the respective light field camera

type. We present a method that extracts a light field from

an arbitrary light field imaging system without knowing and

without modelling the internal optical elements. We calibrate

the camera using a generic calibration procedure, transform

the obtained set of rays into an equivalent light field representation

and finally, reconstruct a rectified light field from the

irregularly sampled data. Experimental results validate the

method and demonstrate that the geometrical structure of the

light field is preserved by an adequate rectification.
