Intrinsic camera calibration equipped with Scheimpflug optical device
Résumé
We present the problem of setting up an intrinsic camera calibration under Scheimpflug condition for an industrial application. We aim to calibrate the Scheimpflug camera using a roughly hand positioned calibration pattern with bundle adjustment technique. The assumptions used by classical calibration methodologies are not valid anymore for cameras undergoing Scheimpflug condition. Therefore, we slightly modify pin-hole model to estimate the Scheimpflug angles. The results are tested on real data sets captured from cameras limited by various industrial constraints, and in the presence of large distortions.
