Three-Dimensional Optical Measurement with Locally Adapted Projection

Abstract:

This paper deals with the measurement and the detection of errors in the threedimensional geometry of high-strength structure components. Firstly different geometrical measuring systems and their usability for the measurement of high-strength structure components are discussed. An optimized solution is suggested, an adaptive projection method based on pattern projection is introduced. The technique takes care of the special properties of high-strength structure components within the production process. The measurement procedure is divided into two steps. Within the adaptation-step the luminescence and the resolution of the projected pattern is adapted on the measured object. The actual picture is taken and calculated in a second step in order to avoid vibrations. The paper concludes with a description of the data processing procedures necessary in order to evaluate the correctness of the measured structure and describes how a 100% geometrical quality control can be achieved using the described methods.
