Abstract (en)
[origin: CA2825678A1] The present invention relates to a method and a device for inspecting an object (1) for the detection of defective surface regions of the object. By means of two-dimensional image data, potentially defective surface regions are located. There are measured surface profiles in at least one cross-sectional plane, which are compared with calculated surface profiles, the located surface region being assessed as actually defective if there is a significant difference. In particular, a coating of a turbine blade can be automatically inspected for TBC shrinkage.
