The present invention provides an imaging device. The imaging device includes a coil array including a plurality of coils, and a control module coupled to the coil array. The control module includes an eddy current measurement unit and an imaging unit. The eddy current measurement unit is configured to drive the plurality of coils to perform an eddy current sensing measurement and acquire a plurality of eddy current sensing results. The imaging unit is configured to form an eddy current sensing image according to the plurality of eddy current sensing results.

A method for identifying indications in an object via non-destructive testing using inspection equipment comprising a probe is described. The method includes: recording test data corresponding to a signal measurement acquired by the probe; processing the test data using a first analysis machine learning algorithm trained to output a list of detected landmarks; processing the list of detected landmarks to identify regions in the object based on the landmarks; processing the test data and the identified regions using a second analysis machine learning algorithm to output a list of detected indications; processing the list of indications to automatically classify each indication according to one of a plurality of predefined indication types; and outputting the classified indications in a report specifying positions of the classified indications in the object. A corresponding system and non-transitory computer-readable medium are also described.
