Select these parameters to compute the orientation of the maximum and minimum radii of objects. The radii are obtained by tracing the object's outside boundary and measuring the distance between the Centroid and boundary points.
AngleRMax returns the angle at which the maximum radius is found.
AngleRMin returns the angle at which the minimum radius is found.
The direction of angle measurements depends on the Y-axis direction in the image calibration scale. If the Y-axis is pointed down (which is a default setting), the angles are measured from the positive X-axis clockwise. To measure the angles counterclockwise, reverse the direction of Y-axis. See Spatial Calibration for more details.
