Get RMSE
Description
Retrieves the Root Mean Square Error (RMSE) if redundant control points were provided when creating the transformation object
Usage
getRMSE(object)
Arguments
object |
Object of the class SimilarityTransformation or AffineTransformation |
Details
RMSE is determined only if Least Squares is applied, i.e., if more than the required control points were provided. The RMSE is useful when comparing two transformations. It measures the general deviation of transformed source coordinates with respect to target coordinates of control points. It has the same units as the coordinates, usually meters.
Value
A number representing the RMSE
