Abstract: A method automatically detects defects during borescoping of an engine. A video borescope is inserted into the engine such that, engine blades can be moved successively through the image region of the borescope. A possible defect on an engine blade is identified by image recognition on the basis of a video borescope frame. The movement of the engine blades in the image region is detected by comparing successive frames. The possible defect is tracked by optical image recognition on the basis of the successive frames used for detecting the movement. In a condition where a trace of the possible defect on the video image corresponds to the detected movement in terms of direction and speed over a predefined length, the possible defect is identified as an actual defect.
