The FPFMS® system uses a CCD camera to continuously collect images of OSB strands that are being conveyed on a flat belt or are dropping in a "waterfall" formation from an elevated chute. These images are then processed through a series of filters and algorithims which calculate the number of edge pixels that are present within each image.
Previous FPInnovations research has shown that actual OSB fines level is strongly correlated with number of edge pixels present. By continuous monitoring, the FPFMS® system can, therefore, minimize losses by identifying excessively high fines levels sooner than conventional methods and reduces the time-consuming task of manual OSB strand shaking.
