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 scond 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.

Abstract: A method of determining position and orientation of an object using a profilometer. A measurement body has a predetermined polyhedral basic form and a defined spatial relationship with the object. The profilometer captures rectilinear coordinates of at least three measurement points lying on a profile line defined by a profilometer scan-line. Using the coordinates and measurement body geometric values, rotations of the measurement body are calculated about a measurement body z-axis, an intermediate y-axis resulting from the z-axis rotation, and about a profilometer-defined x-axis. Next, three translation displacements of the measurement body relative to the three profilometer-defined axes are calculated using the coordinates, the geometric values of the measurement body, and the above-calculated rotations. The position and an orientation of the object is determined by then applying the defined spatial relationship of the measurement body to the object.
