Paper Abstract

In this paper we propose a step-by-step design procedure for image acquisition arrangement planning. An example design for a steel sheet inspection application is presented to illustrate the different phases of the procedure. In the example, the inspection aspects of three different defect types, a dent, a scratch and rough local coating are handled. This design procedure is as follows. Firstly, some important optical parameters of the surfaces to be inspected are measured, for example, scattering, surface roughness, spectrum and polarization properties. Secondly, the optical behavior of the surface is modelled, e.g., by using reflectance models. The third step is to specify the components of the imaging system and to simulate the whole imaging process in a computer by using optical analysis tools. Finally, the simulation results and the real world are compared and the usefulness of the computer based design is evaluated.
