Zusammenfassung:Method, system and computer program for detecting defects in the needles of an automatic knitting machine (1), wherein: a digital camera (4) captures digital image frames (5) of a group (6) of working needles (3); an automatic image recognition is carried out to determine a first pattern jointly defined by the needles (3) and/or a second pattern defined by a length of yarn (7) interacting with the needles (3); at least one parameter is automatically derived from the first or second pattern; a deviation of said parameter from a predetermined reference is automatically calculated; and in function of said deviation, the presence of a defect in the group (6) of needles (3) is automatically determined.
