Calibration fails

  • Make sure that all reference marks from at least one calibration pyramid (or calibration array) are included in the measurement data. The irregular patterns of the calibration marks at the four corners contain a code for determining the spatial position of the calibration structure and must therefore be fully captured.
  • Ensure that the resolution is sufficient to capture the calibration marks. The resolution of your measuring device must be high enough to clearly represent the circular reference marks in the measurement data set. As a general rule, under optimal measurement conditions, a resolution of 512 × 512 measurement points is sufficient for a single pyramid; for the entire array, the resolution should be 1024 × 1024. If the resolution is insufficient for detecting the reference marks, please increase the resolution.
  • Use the scale bar below the display window to check whether the magnification is approximately correct. Marker-based calibration requires an approximate lateral scale calibration (approx. 5%).
  • You may need to adjust the settings for detecting and measuring the calibration marks. For more information, see here: Adjusting the Parameters for Marker Measurement.
