Abstract: An automated optical inspection (AOI) system designed to continuously inspect the width and dual edges of a stainless steel strip is presented in this paper. The study follows this design from its initial conception to its installation, calibration and integration on a production line. The inspection process is based on real time image processing, which measures the strip width, while detects defects and anomalies that could appear at the perimeter of the strip. This is done by processing the acquired images using two linear cameras. Next, the geometrical model and required adjustment are presented. This virtual instrument has been installed for quality control purposes in an annealing and pickling line of a stainless steel factory.
