AUTOMATIC INSPECTION APPARATUS AND METHOD FOR DETECTION OF ANOMALIES IN A 3-DIMENSIONAL TRANSLUCENT OBJECT

摘要

An automated inspection apparatus for simultaneously detecting surface anomalies, embedded anomalies, and semi-transparent edge anomalies in a 3D translucent object, e.g. fish fillet, has a scanhead assembly including conveyor means 140 for moving the object 100 to a scan area, a first source 30 for providing frontal illumination of the object at the scan a second light source 40 for providing back illumination of the object light area, at the scan area, a camera 20 arranged to simultaneously capture front and back illumination image data, a computer processing unit operatively connected to the camera, and a light blocking member 50 formed of a transparent material 58 and of a signal isolation means 60, preferably video paint, for blocking, direct light emitted from the second light source 40, the light block member 50 being arranged coaxially with the camera 20 and the second light source 40.
