A method and arrangement for measuring geometries of an object by means of a coordinate measuring machine

摘要

A method for measuring of substantially two-dimensional geometries or structures of an object with a coordinate measuring machine comprising an image-processing sensor using a the image-processing sensor comprehensive image processing to this sensor system with a connected image memory, wherein said image-processing sensor is adjusted relative to the object, in order either to a plurality of positions of a measuring range or distributed over the entire measuring range to receive partial images and the corresponding partial images in the image memory, to form a complete picture or total measuring image with equidistant pixels over the total image or total measuring image and then to be joined together, the overall or total measuring image to evaluate by means of at least one evaluation unit, for joining together the partial images and the evaluation of the composite fields the image-processing sensor -, - positions for the respective partial images with the image-processing sensor -, - positions for the respective partial images are compared and the fields to the overall picture or total measuring image by mathematical methods in a theoretical pixel pitch with the equidistant pixels, taking into account the difference between the, - and - positions of the image processing sensor are combined.
