Abstract

On the frames of the pedagogic project developed over last four years by the first author “Learning by research”, on this communication we will make a detailed presentation of one research work undertaken by the students on the classes of Image Processing of the Applied Physics undergraduate course of the Physics Department of the University of Minho.

The research work was developed on request from a textile industry company and consists on the automation of the process of defect detection on different kinds of fabrics. The type of defects ranges from broken or missing threads, over casting threads, color and pattern defects. The evaluation is also made on comparison with reference sample. The settled system acquires the fabric’s images under proper illumination, store and process’ them in order to sort out automatically the desired information. The assessment of the pedagogical benefits of this work made by the students them selves will be presented.
