Abstract
Visual inspection is still playing a major role in manufacturing process at product lines. However, the manufacturing process has rapidly become automated in factories. Therefore, automated visual inspection system is highly needed. In this paper, we propose a high-speed and real-time inspection system, which can take the place of visual inspection. The system uses the cylindrical lens for acquiring multidirectional reflected light of one line as an image. Furthermore, it makes the system easy to introduce into product lines. As one of its application, we applied to a scratch inspection, and the result is shown that the proposed system is efficient and effective.
