Adopting the sub-pixel edge extraction algorithm, the equipment can perform high-precision measurement of product dimensions and bending degree, identify various types of surface defects and verify hole position accuracy. Based on powerful algorithms and massive data models, it quickly and accurately judges the quality grade of wood panels. When defective products reach the rejection station, the system controls the rejection device to remove rejects from the production line. It can operate stably for 24 hours, achieving the goals of controllable quality and automated production.
