摘要

The present invention relates to a process for the calibration of an imaging sensor of at least one sensor camera with the use of a temporally coded pattern target, wherein the temporally coded pattern target on a flat image display is displayed, on the flat image display a pattern sequence and displayed by the at least one sensor camera as a sequence of images is received, wherein in the case of a fixed position of the flat image display in the space or in each case for at least two different positions of the flat image display in the space an association between the pixels of the temporally coded pattern target and detected image points of the camera images is carried out, wherein by means of mutually corresponding points on the calibration is performed, wherein a gamma - correction is carried out in the case of the prior to the display of the temporally coded pattern target in an arbitrary position and / or in any position of the flat image displays, together with the lifting of the pattern sequence by the at least one sensor camera a gamma - curve of the flat image display is corrected and received.
