Abstract
A method and an apparatus are provided for contact-free optical displacement and/or vibration measurement of an object, in which the actual positions of the plurality of measurement points are selected and recorded. The display positions of the plurality of measurement points are displayed in the output unit based on a stored or video image of the object. Errors in congruency between the actual positions of the plurality of measurement points and the display positions of the plurality of measurement points are corrected.
