3D Optoelectronic Method for the Steel Strip Flatness Measurement
A real time flatness measurement process is a fundamental issue in the regulation and quality control of the cold rolling steel strip manufacturing. A constant imperative of the quality requirements and the requests for the production efficiency are setting higher and higher standards for the systems used to measure flatness. This paper introduces the concept of the steel strip flatness and analyzes flatness measurement problems, in the particular near edges of the steel strip. Our work presents a solution using of 3D optoelectronic system that successfully overcomes the limitations of the traditional flatness measuring systems. By projecting the laser line and its detection on the camera image, we successfully obtain data, in real time, to compute the shape profile of the strip. A reconstructed strip profile is used for detection of a strip flatness defects and position of the steel strip edges, which is a common quantity for a flatness evaluation. A described 3D optoelectronic method is demonstrated using a custom made laboratory simulator aimed to simulate realistic strip defects.
