Abstract

Continuous classification of board firmness and knotting is provided from classification unit (116). Knot data and board thickness is provided from X-ray scanner (120) and board rigidity from natural frequency measurement unit (102) and camera system (114). Elasticity module is calculated from length of board, and is used to determine solidity.
