Abstract

The paper presents a granule appearance recognition system in the plastic production process. In the industry, granule product shape is one of the important quality index. Abnormal granule shape products are as waste products some times. But in the automatic process, it is too difficult to test the granule shape one by one, when the product quantity is great. The automatic recognition system we proposed is designed for distinguishing the normal granule or abnormal granule shape of plastic products in the process line and giving the percentages of them. The methods (8 chain code, automatic threshold selection...) we used realize the rapid granule shape test, therefore the good quality products are obtained.
