摘要： A method of defining deviations from a desired position of pixel sites in an image recording matrix by defining the 3-D data of a planar or slightly curved surface. To the extent necessary the results are smoothed, and the measuring points, utilizing the 3-D data, are projected back the sensors of the image recording matrix for determining the difference between the two points projected onto the sensors and associated with a 3-D measuring point. After selectively shifting the surface relative to the 3-D measuring system, prior method steps are repeated until the desired accuracy in the definition of the deviation has been has been attained.

摘要： According to the invention, a method for detecting and measuring local shape deviations in flat, curved, or domed surfaces of a test object, wherein three-dimensional measurement data (D) of the surfaces are evaluated by means of an evaluating apparatus, is designed and further developed, with regard to nondestructive testing of test objects with objective and easy-to-interpret assessment results, in such a way that the evaluating apparatus uses at least one virtual filter element as a concave filter for detecting concave sub-areas in flat or convex surfaces and/or as a convex filter for detecting convex sub-areas in flat or concave surfaces, that the filter element determines magnitudes of the shape deviations, and that said magnitudes are output by means of an outputting apparatus as measured values. The invention specifies a device for performing a corresponding method.
