A system (100) for identification of defects on a surface (210) of at least one portion of a body (200), said system (100) comprising an optical detection device (110) arranged to acquire data on the three-dimensional shape of the surface (210) and first moving means (120) arranged to drive the optical detection device (110). The system (100) also comprises at least one control unit arranged to localize the body (200) with respect to a predetermined reference system S, actuate the first moving means (120) to move the optical detection device (110) along a trajectory y defined with respect to the predetermined reference system S, receive the data on the three-dimensional shape of the surface (210) by the optical detection device (110), detect a possible defective area (215) on the surface (210) and define a three-dimensional geometry of the defective area (215). |
