Abstract:
A method for capturing and measuring translation and/or rotation of a component moving relative to a reference system includes providing a marker on the component and providing a measurement system having a camera arranged in the reference system. The marker has at least three points which do not lie on a straight line on an upper side of the marker and the camera has an evaluation unit and memory that stores a geometry of the upper side including the at least three points. The camera is aligned with the at least three points and a first image of the marker located in a first portion is captured and stored and a second image of the marker in a second position that is different than the first position is stored. Also, translation and/or rotation of the component in three-dimensional space between the first position and the second position is calculated.
