Self-calibration of Scheimpflug cameras: an easy protocol

The problem of the self-calibration of Scheimpflug cameras is addressed. The approach aims to calibrate by handpositioning a roughly-known calibration pattern, thanks to a bundle adjustment technique. The purpose of this paper is to design an easy protocol accordingly. A simple motion of the calibration target is introduced and a minimal number of recordings are obtained from the simulated data. The precision required for the calibration pattern is also discussed. Finally, the suggested protocol is tested in real conditions, especially in the stereo particle image velocimetry configuration.
