Claim One:
1. Method for calibrating a stage-camera system, comprising the steps of: providing a stage-camera system ( 12 , 14 , 16 , 28 , 29 ) with a stage ( 12 ) and a camera ( 28 ), wherein the stage ( 12 ) and the camera ( 28 ) are arranged relative to one another in a reference position (S 0 ), and at least one object (O 1 , O 2 ) is arranged on the stage ( 12 ) in a recording region ( 34 ) of the camera ( 28 ), recording a reference image (P 0 ) of the at least one object (O 1 , O 2 ) in the reference position (S 0 ), moving the stage-camera system ( 12 , 14 , 16 , 28 , 29 ) with at least one electric drive motor ( 14 , 16 ) such that the stage ( 12 ) and the camera ( 28 ) are arranged relative to one another in a calibration position (S 1 ), wherein the calibration position (S n ) is different from the reference position (S 0 ), and at least a portion of the at least one object (O 1 , O 2 ) is located in the recording region ( 34 ) of the camera ( 28 ) in the calibration position (S n ), recording a calibration image (P n ) of the at least one object (O 1 , O 2 ) in the calibration position (S n ), determining a travel distance (Δx 1 (n), Δy 1 (n)) from the reference position (S 0 ) to the calibration position (S n ) in a first coordinate system (K 1 ) with an electronic control device ( 29 ), registering the calibration image (P n ) with the reference image (P 0 ) based on the at least one object (O 1 , O 2 ) with the electronic control device ( 29 ), determining an object displacement distance (Δx 2 (n), Δy 2 (n)) in a second coordinate system (K 2 ) based on the registered calibration image (P n ) with the electronic control device ( 29 ), and determining a calibration measure (A) from the travel distance (Δx 1 (n), Δy 1 (n)) and the object displacement distance (Δx 2 (n), Δy 2 (n)) for calibrating the coordinate systems (K 1 , K 2 ) with the electronic control device ( 29 ).
