Method for calibrating an irradiation device () for additively manufacturing three-dimensional objects which irradiation device () comprises at least two irradiation units (), comprising: guiding one of the at least two energy beams () via the corresponding irradiation unit () to a determination region (), preferably a part of a build plane (), for generating a calibration pattern (); imaging at least one part of the determination region () to an on-axis determination unit () of the at least one other irradiation unit (); determining a position of the calibration pattern () in the determination region () on basis of the image of the at least one part of the determination region (); generating calibration information relating to a calibration status of at least one part of the irradiation device () based on the position of the calibration pattern ().
