Abstract:	Extrusion tube is a very popular product in the plastic industry produced by a extruder machine, for example, tubes used in washer machine or in reverse osmosis (RO) water purification system. To guarantee the quality of the tube produced for medical use, a surface defect detection system is needed. In this paper, we use a single camera combined with a telecentric lens and properly designed mirror set to achieve the complete coverage of the object surface for full defect detection. Based on the properly designed image acquisition equipment and image analysis techniques, the final system for extrusion tube defect detection can successfully detect defects of black spots, bumps, injury, etc., with a defect detection rate of about 95%, and the detection speed is up to 1578 mm/s. This speed of detection makes the detection system can be deployed on the production line without interfering the operation of the tube machinery.
