When Does a CCD Camera Have to Be Calibrated?
During the calibration of the CCD camera, a linearization of the measuring range is carried out. In doing so, the measuring deviations that are caused by the optic properties of the zoom lens are automatically compensated.
With high demands to the measuring accuracy, a CCD camera must be calibrated during / after the following work:
- For the first start-up of the CCD camera
- After cleaning a dirty camera lens
