Abstract

Flatness of surface is of great importance in industrial products such as steel sheets. In many cases, the quality of the final product is directly linked to the flatness of its components. One possible defect in the production of hot strip mill steel sheets is the straightness defect which results in flatness asymmetries in the steel sheets, causing a certain curvature on its edges. This defect is more likely to occur at the final stages of the hot strip mill. The deformation may cause stoppages in the rolling process and damage to the machinery. Detection and measurement of these asymmetries can be fed back to the previous stages of the rolling process for proper adjustment of the roller's speed to avoid further defects. Nowadays, a family of methods for surface detection, called TOPOMETRY, is available for measurement of surface flatness asymmetries. In this paper, a method is proposed based on Interferometric Fringe Projection (IFP) which performs the FLATNESS MEASUREMENT. The proposed method has the advantage of simplicity and can, hence, be used in real-time applications.
