Method for applying paints to surfaces in a controlled, position-dependent manner

A method for applying paints or varnishes to large surfaces by means of a displaceable, paint applying tool, which is controlled in a position-dependent manner and contains a displaceable part of a real-time position measuring system that is used to measure its position and which relies on positionally fixed reference marks, characterized in that the position of a reference mark of the real-time position measuring system is determined by employing the real-time position measuring system or another position measuring system that relies on the reference marks,

• by introducing a number of reference marks in fixed position relative to the surface and by positioning the displaceable part of the real-time position measuring system or the displaceable part of the other position measuring system at several points of the surface, and by measuring for the individual points distance and/or angular position between the displaceable part of the position measuring system employed and reference marks by means of the position measuring system employed, and by determining therefrom the position of the a reference mark,
• and/or by determining the position of a point relative to the surface by means of the real-time position measuring system or the other position measuring system by relying on marks of known position, by introducing a reference mark at this position, and by assigning the measured position to the reference mark.
