摘要: A method is described for measuring workpieces, each having structural features that form test features for measurement. The method determines an unstable one and a stable one of the test features, based on expected violation or satisfaction, respectively, of a statistical control rule. The method measures workpieces such that the unstable test feature is measured more frequently than the stable test feature. The method ascertains whether the unstable test feature remains unstable and whether the stable test feature remains stable. The method measures additional workpieces if the unstable test feature remained unstable and the stable test feature remaining stable. The determining is repeated if the unstable test feature is no longer unstable, the stable test feature is no longer stable, or any other measurement feature changes, such as if a new batch of workpieces is to be measured, environmental conditions change, or measurement has proceeded longer than a predefined threshold.

摘要: An optical measuring system includes a calibration apparatus having at least one optical marker and a code. The optical measuring system includes a memory unit that stores a metadata record with calibration parameters that have physical state and change variables that are specific to the calibration apparatus. The calibration apparatus is configured to encrypt a link to the metadata record stored in the memory unit. The optical measuring system includes an optical sensor configured to capture image data containing the at least one optical marker and the code. The optical measuring system includes a control unit configured to evaluate the image data captured by the optical sensor, decrypt the code captured by the optical sensor, access the memory unit via the link, read the metadata record stored therein, and include the read calibration parameters and the at least one optical marker in the evaluation of the image data.

摘要: A method for correcting a detector configured to generate object radiographs and an arrangement to implement the method is provided. The method includes the steps of (a) providing the detector having setting values for a gain and offset correction, (b) capturing a plurality of object radiographs of a test object by the detector and generating a reconstructed three-dimensional representation of the test object based on of the object radiographs, (c) determining at least one quality value of the reconstructed three-dimensional representation, repeating the steps (b) and (c) at least once, wherein before the repetition, a parameter set is generated and a measurement sequence is implemented on the basis thereof, at least one setting value for a gain and offset correction of the detector being determined anew based on the measurement sequence; and (e) determining a preferred gain and offset correction based on overall determined quality values.

摘要: An event classification is trained by machine learning. An anomaly detection for detecting events in an image data set is thereby performed. Based on the performance of the anomaly detection, a model assumption of the event classification is determined. An image data set may include a plurality of images, and each image may include an array of pixels. Further, an image data set may include volume data and/or a time sequence of images and in this way represent a video sequence.

摘要: A method is described for determining a relative position of an axis of rotation of a rotary table of a coordinate measuring machine. The rotary table has or forms a reference element that is arranged eccentrically in relation to the axis of rotation. The method includes a measuring step including performing a rotary movement of the rotary table, and producing measuring points that encode a position of the reference element by a sensor of the coordinate measuring machine during the rotary movement. The method includes a determining step including determining the relative position of the axis of rotation of the rotary table based on the measuring points.

摘要: A method for creating a measurement protocol in a computer, such as the measurement computer of a coordinate-measuring machine or a computer remote therefrom, includes: providing data necessary for creating a measurement protocol generated on the basis of a measurement sequence by the coordinate-measuring machine; providing specification data specifying predefined conditions under which a measurement sequence should be performed and/or specifying predefined conditions under which examination features should be evaluated; checking the data necessary for creating a measurement protocol as to whether the predefined conditions under which the entire measurement sequence should be performed were met and/or as to whether the predefined conditions under which individual examination features to be examined should be evaluated were met, and; creating a measurement protocol in the form of an electronic document, in which compliance and/or non-compliance with the conditions in accordance with the specification data is documented in the measurement protocol.
