Helmert Transformation Procedure


Helmert Transformation Procedure
is intended for calculating Helmert transformation parameters by the least squares iteration routine. In the process of performing this operation Helmert Transformation Procedure gives an opportunity to interactively exclude the fault points on the stage of preliminary calculations, and after calculating residuals. Besides, a tolerant residual may be set, so all the points wth residuals exceeding the tolerance, will be excluded automatically.
Data may be entered directly into the table,or come from an ASCII file, with lines representing a point in two coordinate systems XYZ and UVW: The second way is realized in the Run and Offset procedure, where data must be presented in two ASCII files, one with points to be tansformed, an the second, containing some of the points from the first file but in the coordinate system, in to which the points from the first file are to be transformed.
