Method and Device for the Automatic Inspection of a Cable Spool |
摘要 |
Method for detecting and evaluating the protrusions that appear on cords coming from a twisting/rubberizing process, by the digital processing of the image of a layer of cord formed by a number of turns wound around the core of a spool (4), which method comprises the steps during which: A) the raw digital image of the surface of the layer of cord over one complete revolution of the spool is taken using a linear camera (1); B) the raw image is displayed flat so as to limit the influence of the variations in lighting and in the brightness of the wires; C) the flattened image is segmented so as to reveal the dark areas that contain protrusion areas; D) the segmented image is a processed using a series of morphological processing operations in order to separate and select the shapes likely to represent protrusions and areas likely to represent shadows; and E) an evaluation value is assigned to the final image obtained and the evaluation value is compared with a threshold value. |
