The Thresholding tab allows you to set the limits beyond which data will be discarded (leaving ‘holes’ in the plot). Raising a
threshold will always allow more data.
• Prediction margin: discards points that are inconsistent with neighbors. This is the most useful threshold for
limiting false matches.
• Projection error: discards matches which seem unrealistic with regards to the calibration.
• Confidence interval: discards matches which have a high uncertainty due to defocus, highlights, pattern
degradation, etc. This option can be very useful for discarding data around cracks that grow during the test.
The Stereo margin option applies only to the left-right match
• Matchability: discards matches which have poor contrast.
