    摘要: The present disclosure relates to a method and device for evaluating a wooden board with an elongated direction. Data indicating fiber orientation over the surface of the board is acquired and for a number of board sub-portions a nominal local modulus of elasticity, MOE, is determined based on the fiber orientation data and a nominal material parameter. A nominal global MOE in the elongated direction for the wooden board as a whole is generated and compared with a secondary global MOE. Based on the fiber orientation data and this comparison an estimated local modulus of elasticity, MOE, in said elongated direction is generated for a number of board sub-portions. This data may be used e.g. for reliable strength grading of wooden boards.
