摘要： A method and device for performing the method of inspecting an object for the purpose of detecting defective surface regions of the object, comprising the steps of using a scanning device to survey a surface of the object to be inspected and generating two-dimensional image data and a measured surface profile in at least one cross-sectional plane through the object in each case; using a computer device to evaluate the two-dimensional image data in order to localize a potentially defective surface region; using the computer device to generate a calculated surface profile within the potentially defective surface region in the cross-sectional plane on the basis of the measured surface pro-file outside of the potentially defective surface region of the cross-sectional plane; using the computer device to compare the calculated and measured surface profiles within the potentially defective surface region, the localized surface region being assessed as actually defective if defined differentiating features are present.
