Abstract
A method and an apparatus for determining a plurality of spatial coordinates on a measurement object using a working head having an image sensor for recording images of the measurement object. A first image of a first feature of the object with the working head in a first working position is recorded. First spatial coordinates representing a spatial position of the first feature are determined using first position information of the working head supplied by an encoder arrangement. The working head is then moved relative to the object to a second working position, where a second image of the object is recorded. Using the first and the second images, second position information which represents a spatial offset of the working head relative to the object is determined. Spatial coordinates for a second feature of the measurement object are determined on the basis of the second position information.
