The 3D Helmert transformation is a frequently used method in geodesy to produce transformations between different cartesian coordinate systems:

Xt = transformed coordinate vector X = initial coordinate vector T = translation vector R = rotation matrix including rx, ry, rz rx, ry, rz = rotations around the coordinate axes s = scale factor ...
