Abstract

Due to recent developments in sheet-bulk metal forming processes,
holistic measuring systems are required which provide reliable results
for the measurement of all relevant formed part features. The presented
multi scale multisensor approach, which combines several fringe
projection sensors of different measuring resolutions and ranges,
accomplishes the requirements of the new production technology.
Calibration of the single measurement systems to a global coordinate
system is realized with a specially developed calibration object. A
high-precision hexapod positions the calibration object and the
workpiece within the measuring range. The result is a holistic
dimensional measurement for characteristics whose size exceeds the
measuring range of a single sensor. It is also shown that the distance
of the measurement sensor to the suface of the measurement object is
relevant for the uncertainty of the obtained point cloud. By positioning
the workpiece in the focus of camera of the fringe projection system,
the standard deviation of the measured point cloud can be significantly
reduced.
