Paper Abstract

A self-calibrating 3D measurement system using structured- light illumination with a digital-light projection unit (DMD) will be reported, which ensures a high number of object points, quick data acquisition, and a simultaneous determination of coordinates and system parameters (self calibration), making the system completely insensitive to environmental changes. Furthermore, there is no necessity of any marker on the object surface and a subsequent matching of the single views is not required to obtain a full-body measurement. For this reason, the object under test is successively illuminated with two grating sequences perpendicular to each other from different directions resulting in surplus phase values for each measurement point. On the basis of this phase value one can calculate the orientation parameters as well as the 3D-coordinates online. Two different measurement set-ups will be reported, which have the ability to measure the entire surface (full-body measurement).
