摘要： A method for determining and verifying ply orientation of composite laminates includes performing a first scan of a prepared edge of a composite laminate using an off-axis inclined light source directing light at a first acute angle to a first area on the prepared edge to produce a first scanned image; rotating an orientation of the off-axis inclined light source relative to the prepared edge, such that the off-axis inclined light source directs light at a second acute angle symmetrically opposite the first acute angle; and performing a second scan of the prepared edge using the off-axis inclined light source directing light at the second acute angle to the first area on the prepared edge to produce a second scanned image. The method includes comparing the first and second scanned images to determine a ply orientation of each ply, and verifying the ply orientation against a baseline ply orientation.

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.

摘要： This invention provides accurate, high quality images for the identification of the surface characteristics of an object, that may be used as an input to suitable industrial process. It involves acquiring a first raw scan of a portion of a target object across a scan line in a scan zone with a first camera and simultaneously acquiring a second raw scan of the same portion of the target object across the scan line in the scan zone with a second camera. The raw scans are converted to digital and then processed with flattening coefficients derived from measurements of variations in illumination. The first and second cameras sets of flattened image data are then gridized to compensate for parallax, make them orthographic sets of image data that can be compared on a pixel-by-pixel basis with a known or measured geometric profile of the target. A selection of enhanced pixel value for a surface coordinate can then be made, based on both sets of data. The obscuring of surface features by specular reflection can thus be effectively eliminated.
