Abstract:
1. A method for detecting the three-dimensional structure of a log, the log having a main direction of extension (D), the log having a lateral surface and two end surfaces, the lateral surface having irregularities, the lateral surface having a structure which is defined by a plurality of points, the lateral surface comprising a plurality of lateral surface portions ( 13 ), each lateral surface portion ( 13 ) having a structure which is defined by a group of said points; the method comprising the steps of: making the log ( the method being characterized in that wherein (a) each structure of a lateral surface portion ( 13 ) detected shares several points with at least one other structure of a lateral surface portion ( 13 ) detected, and/or (b) at least two additional detection steps are performed, each additional detection step comprising detecting one or both end surfaces of the log simultaneously with a corresponding detection step of the structure of a lateral surface portion ( 13 ), wherein several points are shared by the results of the at least two additional detection steps; and wherein the step of combining the locations is carried out in such a way that (a) the points shared by two different detected structures of lateral surface portions (
