A calibration method for a measuring system, wherein the measuring system is designed to determine a positioning of an object (12, 22, 32) that is to be positioned in a defined fashion, and comprises at least - a first recording apparatus (1, 1a) with ∘ a first camera (2, 2a) for capturing a first image within a first field of view (8, 8a) and ∘ a first angle measuring unit (4, 4a) for very precisely determining a first angular alignment of the first camera (2, 2a), wherein the following steps are performed within the scope of the calibration method: - carrying out calibration measurements of a calibration measurement cycle comprising the capture of calibration measurement data, wherein the calibration measurement cycle has at least such a number and variety of calibration measurements that calibration parameters can be determined on the basis of the captured calibration measurement data, said calibration parameters at least relating to position and orientation of the first recording apparatus (1, 1a) in a defined coordinate system, and - establishing the calibration parameters on the basis of the calibration measurement data, characterized in that - the calibration measurement cycle is subdivided into a plurality, more particularly a number of partial cycles (TZ1, TZ2, TZ3, TZ4, TZ5, TZ6, TZi), with one or more of the calibration measurements being associated with each of these, and, - while maintaining a known cycle (Ta), the partial cycles (TZ1, TZ2, TZ3, TZ4, TZ5, TZ6, TZi) each take place in time windows determined by the cycle such that the calibration measurement cycle is distributed over a plurality, more particularly a number of time windows. - a first recording apparatus (1, 1a) with ∘ a first camera (2, 2a) for capturing a first image within a first field of view (8, 8a) and ∘ a first angle measuring unit (4, 4a) for very precisely determining a first angular alignment of the first camera (2, 2a), wherein the following steps are performed within the scope of the calibration method: ∘ a first camera (2, 2a) for capturing a first image within a first field of view (8, 8a) and ∘ a first angle measuring unit (4, 4a) for very precisely determining a first angular alignment of the first camera (2, 2a), - carrying out calibration measurements of a calibration measurement cycle comprising the capture of calibration measurement data, wherein the calibration measurement cycle has at least such a number and variety of calibration measurements that calibration parameters can be determined on the basis of the captured calibration measurement data, said calibration parameters at least relating to position and orientation of the first recording apparatus (1, 1a) in a defined coordinate system, and - establishing the calibration parameters on the basis of the calibration measurement data, characterized in that - the calibration measurement cycle is subdivided into a plurality, more particularly a number of partial cycles (TZ1, TZ2, TZ3, TZ4, TZ5, TZ6, TZi), with one or more of the calibration measurements being associated with each of these, and, - while maintaining a known cycle (Ta), the partial cycles (TZ1, TZ2, TZ3, TZ4, TZ5, TZ6, TZi) each take place in time windows determined by the cycle such that the calibration measurement cycle is distributed over a plurality, more particularly a number of time windows.
