- Helmert_transformation abstract "The Helmert transformation (named after Friedrich Robert Helmert, 1843–1917; also called a seven-parameter transformation) is a transformation method within a three-dimensional space. It is frequently used in geodesy to produce distortion-free transformations from one datum to another using: where XT is the transformed vector X is the initial vectorThe parameters are:— translation vector. Contains the three translations along the coordinate axes— scale factor, which is unitless, and as it is usually expressed in ppm, it must be divided by 1,000,000.— rotation matrix. Consists of three axes (small rotations around the coordinate axes) , , . The rotation matrix is an orthogonal matrix. The rotation is given in radians.Thus, the Helmert transformation is a similarity transformation.".
