Detailed Description

A dimension accuracy estimate for a specific working volume

Member Function Documentation

◆ dimensionAccuracy()

ZIVID_CORE_EXPORT float Zivid::Experimental::Calibration::AccuracyEstimate::dimensionAccuracy ( ) const

The estimated dimension accuracy obtained if the correction is applied

This number represents a 1-sigma (68% confidence) upper bound for dimension trueness error in the working volume (z=zMin() to z=zMax(), across the entire field of view). In other words, it represents the expected distribution of local dimension trueness measurements (see CameraVerification) that can be expected if measuring throughout the working volume.

The returned value is a fraction (relative trueness error). Multiply by 100 to get trueness in percent.

Note that the accuracy close to where the original data was captured is likely much better than what is implied by this number. This number is rather an accuracy estimate for the entire extrapolated working volume.

Returns
A 1-sigma (68% confidence) upper bound for trueness error in the working volume

◆ toString()

ZIVID_CORE_EXPORT std::string Zivid::Experimental::Calibration::AccuracyEstimate::toString ( ) const

Get string representation of the accuracy estimate

Returns
Accuracy estimate as string

◆ zMax()

ZIVID_CORE_EXPORT float Zivid::Experimental::Calibration::AccuracyEstimate::zMax ( ) const

The range of validity of the accuracy estimate (upper end)

Returns
Maximum z-value of working volume in millimeters

◆ zMin()

ZIVID_CORE_EXPORT float Zivid::Experimental::Calibration::AccuracyEstimate::zMin ( ) const

The range of validity of the accuracy estimate (lower end)

Returns
Minimum z-value of working volume in millimeters
