Refinement

Extracting sub pixel accurate center points of the calibration pattern in blurred and distorted raw images is not a trivial task. Therefore the CollectPattern command provides a refinement procedure to increase the accuracy of the point centers. The procedure tries to compensate for blur and perspective distortion in the point detection process.

Refinement will improve pattern detection accuracy especially when the camera lenses exhibit a significant amount of distortion, blur or both.

Format

Boolean

false

Do not use pattern point refinement.

true

Refine pattern point coordinates immediately during collection.

Note

For backwards compatibility, the old string parameter values “None” and “Immediate” instead of the boolean false and true are still supported.

Default

true

Note

When the Projector parameter is enabled, refinement is not supported and will automatically be set to false .
