Description

errorMap float* The error map for the calibration. The error map will be empty if the function did not calculate it when learning the calibration.
mapColumns int The number of columns in the error map.
mapRows int The number of rows in the error map.
userRoi ROI* Specifies the ROI the user provided when learning the calibration.
calibrationRoi ROI* Specifies the ROI that corresponds to the region of the image where the calibration information is accurate.
options LearnCalibrationOptions Specifies the calibration options the user provided when learning the calibration.
grid GridDescriptor Specifies the scaling constants for the image.
system CoordinateSystem Specifies the coordinate system for the real world coordinates.
range RangeFloat The range of the grayscale the function used to represent the circles in the grid image.
quality float The quality score of the learning process, which is a value between 0-1000. A quality of 1000 means that the function learned the feature points perfectly with the chosen algorithm. It does not necessarily reflect the absolute accuracy of the estimated calibration mapping, but instead reflects how well the calibration mapping adapts to the learned points.
