Abstract

The ever-increasing demand for quality goods call for more and more efficient inspection systems in order to reduce the amount of scrap. Especially for natural products like wooden boards it is necessary to have an early classification and fault detection in order to manufacture an optimal product. An optimal solution was found using the, at that time, newly developed SBIP/L (Single Board Image Processor for Line Cameras). The problem was to inspect the boards from all four sides with an image processing system and detect and classify the faults on the lateral surfaces. This year RMV E&S presented a new system based on the SBIP/L combined with a color line camera from DALSA thus significantly enlarging the range of its wood inspection systems. This system allows the detection of color faults on wood (e.g. blue stains). Of course, the color fault analysis can be used for the inspection of other continuous materials as well.
