Abstract
Method and system for calibrating a camera (12) in the working chamber (10) of a production machine. A calibration object (24) inside the working chamber (10) of the machine is brought to different positions and its picture is taken by the camera (12). The position parameters of the calibration object (24) are assigned to the corresponding pictures taken by the camera (12). The parameters of the camera (12) can be determined on the basis of the thus determined data. According to the invention, the different positions of the calibration object (24) inside the working chamber (10) are determined using the measurement system of the machine in order to obtain particularly precise parameters of the camera (12), the parameters of the camera (12) being determined taking into account the data from the measurement system of the machine.
