The calibration of the system takes place with a calibration grid held in front of the camera. mvIMPACT analyses this grid and calculates the transformation data automatically. The adjustment of the distortions can be achieved with an image transformation. After this transformation the user receives a corrected image which can be used with existing algorithms to get calibrated measurement results.

The calibration module also provides functions for coordinate transformations. The modules mvIMPACT Blob and mvIMPACT Measure use the coordinate transformation functions automatically to get calibrated measurement results.

In contrast to the general trend, increasing application complexity does not mean a loss of usability. The mvIMPACT Calibration module features easy handling during the identification of distortions.
