CA 2348363

A lumber grading system for providing a lumber cutting solution for a piece of lumber. Video acquisition circuits acquire complementary images of the sides of the piece of lumber taken by two cameras. A computer unit performs an image processing of the images and generates the lumber cutting solution for the piece of lumber based on preset grade determination parameters. The image processing involves a longitudinal division of the images of the piece of lumber into a number of consecutive zones based on predetermined lumber cutting positions, an attribution of respective grades to the zones based on an image analysis of the zones as a function of the preset grade determination parameters, and a solution search providing the lumber cutting solution as a function of the grades attributed to the zones. A communication circuit transmits the lumber cutting solution.
