Method for correcting measuring errors caused by the lens distortion of an objective

摘要

A method for correcting the measuring errors caused by the lens distortion of an objective in a coordinate measuring machine is disclosed. For a plurality of different types of structures, the lens distortion caused by an objective is determined in an image field of the objective. The position of a type of structure is determined in the image field of the objective by a measuring window. The correction of the lens distortion required for the type of structure to be measured is retrieved from the database as a function of the type of structure to be measured.
