Automatic registration method for hybrid optical coordinate measuring technology

A method to create holistic data models of complex, partly multiscale, workpieces is presented and verified on cutting tools. Different optical sensor principles are applied and the registration strategy is developed to transform partial views taken with single sensors into one coordinate system. Focus of the work is the implementation of automatic registration procedures, based on correlation and segmentation. These novel approaches in coordinate measuring technology are tested and compared. The method is completed by fusing all datasets to one holistic data model, considering the geometry of the workpieces by applying a curvature based segmentation.
