Calibration quality

The Calibration quality page contains setting for how to detect if the cameras needs to be calibrated. The check can be performed in two different ways.

• Residual settings
  This will test in the 3D tracker if the cameras have a Residual in the File information on the View menu that is higher than the residual check. The default value for the residual test is 3 mm. It also tests if there are too few of the captured 2D markers used by the 3D tracker, i.e. the number of Points. If a camera is considered to be uncalibrated, then there is a warning after the tracking of the file.

• Show calibration quality warnings when retracking too
  Use this setting if you want to check the calibration quality when you retrack a file.

• Time settings
  This test will only check how long a calibration is considered as new. The calibration will still be used in a measurement it is just a visual warning. When the time set with A calibration is new for has passed the triangle at the bottom right corner turns yellow . Then when the time A new calibration is recommended after has passed the triangle changes to orange .
