Patent number: 10935366Abstract: A method and device for geometrically determining features of a workpiece, having an image processing sensor having a first beam path, the first beam path comprising at least one front optical unit facing the workpiece to be measured, and an optical splitter being mounted on the side of the front optical unit facing away from the workpiece. The optical splitter connects a second beam path to the image processing beam path, a common beam path being formed, and the second beam path being associated with a second optical sensor, the image processing sensor and the second sensor being designed to directly measure the surface of the workpiece. The front optical unit is formed as a sphere and/or has a longitudinal chromatic aberration.Type: GrantFiled: December 11, 2015Date of Patent: March 2, 2021Assignee: WERTH MESSTECHNIK GMBHInventors: Ralf Christoph, Ingomar Schmidt, Volker Wegner, Matthias Andräs, Ulrich Neuschaefer-Rube, Andreas Ettemeyer, Mehmet Demirel, Sabine Linz-Dittrich, Benjamin Hopp

Patent number: 9599456Abstract: The invention relates to a method and arrangement for determining structures and/or geometry of a workpiece in a coordinate measuring machine by means of a tactile-optical measuring method, wherein the position of a shaped probe element is determined in at least one direction by means of a first sensor using an optically lateral measuring method, and the position of the shaped probe element is determined in at least one second direction using at least one distance sensor. In order to allow the error-free detection of the shaped probe element using the sensors, the invention proposes that at least one flexible connector element is used in a mounting for fastening the shaped probe element, permeated by the beam path of the first sensor in the beam direction, wherein the connecting element is transparent and/or is disposed severely out of focus with respect to the first sensor.Type: GrantFiled: November 26, 2010Date of Patent: March 21, 2017Assignee: WERTH MESSTECHNIK GMBHInventors: Ralf Christoph, Matthias Andräes, Ingomar Schmidt, Markus Hechler, Benjamin Hopp
