Measurement and data processing uncertainly issues in optical, full-field measurement techniques

In the paper we discuss some metrological issues connected with measurement and data processing procedures of optical, full-field techniques applied for 3D objects investigation. The methodology presented is focused on determination of final uncertainty of results based on knowledge about uncertainties introduced by each contributing module. It is shown that in complex system the measurement uncertainly should be determined experimentally on the base of comparison of measurement results and certified model data, while the processing uncertainties determination may be based on numerical experiments (comparison with virtual model). The exemplary uncertainly determination paths for true 3D shape measurements of biological and technical objects are presented.
