Method for registering the actual representation of an object to be measured with the desired representation of the object to be measured

摘要

It is proposed a measurement object with a predetermined description MS of the measurement object a process for the registration of the Istbeschreibung MI, said Istbeschreibung MI represents the actual geometrical dimensions, the actual position and the actual orientation of the measurement object and defined with the target description MS geometrical dimensions, a defined position and a defined orientation are set for the DUT. The elements of the Istbeschreibung Ml be detected, and the elements of the target MS description are given for example in the form of a CAD description. According to the invention a transformation T to the orientation of the measurement object is determined according to its nominal description in an iterative process. For this to MI and MS default values ​​are defined, which corresponds to a feature extraction from measurement data and CAD description. Then, corresponding elements from Ml and MS are either determined or calculated by determining the target values ​​to the default values. The targets extend the other set.
