Abstract
A device for detecting the presence of abnormalities in a reel includes an image capturing module for capturing images of the reel including at least one camera, a displacer for displacing the reel in a field of view of the at least one camera, an analyzer for analyzing the images captured by the at least one camera and detecting the presence of abnormalities. The image capturing module including an upper capturer and lower capturer, the upper capturer fixed on a movable support arranged for being movable with respect to lower capturer, the upper capturer and/or the lower capturer including at least one three dimension camera arranged for providing a three dimension image of the reel.
Claims16
A device configured to detect the presence of abnormalities on an external surface of a reel, the device comprising:
- an image capturing module configured to capture images of the reel, the image capturing module comprising at least one camera;
- a displacer configured to displace the reel in a field of view of the at least one camera;
- an analyzer configured to analyze the images captured by the at least one camera and to detect the presence of abnormalities, wherein the abnormalities are configured to define failures on the external surface of the reel including misaligned core of the reel, reel core dimensions default, crushed reel core, reel width variation, reel diameter variation, irregular reel side, reel telescoping effect, waving of the reel, and color contamination of the reel;
- wherein the image capturing module comprises an upper capturer configured to capture images of an upper face of the reel, and a lower capturer configured to capture images of the lower face of the reel, the upper capturer fixed on a movable support arranged for being vertically movable with respect to the lower capturer between a first vertical position and a second vertical position where the upper capturer is closer to the reel than when the movable support is in the first position, the upper capturer comprising at least one first camera that includes at least one three dimension (3D) camera arranged to provide a three dimension (3D) image of the reel and the lower capturer comprising at least one second camera;
- and
- a computing arrangement configured to compute at least one parameter of the detected abnormality, including at least one dimension of the abnormality, wherein the computing arrangement is configured to determine if the reel should be rejected based upon the abnormality.
