Abstract: This invention relates to a method for non-destructive inspection of a log (1) to identify inner zones of sapwood (14) of the log (1) that have not been attacked by fungi that cause bluestain in the wood. The method comprises a first step of carrying out a tomographic scan of the log (1) to be inspected using X-ray beams that pass through the log (1) and a second step of obtaining a three-dimensional representation of the log (1) that is representative of the local moisture content of the log, the local moisture content being correlated with attenuation of the X-ray beams through the log. The method comprises the step of processing the three-dimensional representation of the log (1) to identify inner regions (145) of the log (1), in which the local moisture content is greater than or equal to a moisture threshold value for a spatial extent greater than an extent threshold. The moisture threshold value corresponds, for trees of the same species as the log (1), to a sapwood (14) with local moisture content such that it excludes the growth of fungi that cause bluestain in the wood. Each inner region (145) identified in this way is classed as a sapwood (14) zone free of bluestain. This invention also relates to a procedure for obtaining one or more wooden products from a log (1), as well as an apparatus for carrying out a non-destructive inspection of a log (1).

Abstract: This invention relates to an apparatus (1) for carrying out a non-destructive inspection on a wooden board (9) or a similar object. The apparatus (1) comprises a movement system (3) comprising at least two chains or belts (32) that are at a distance from one another and substantially parallel to each other. The chains or belts (32) are slidable parallel to a movement path (30) and are and intended to support the wooden board (9). The apparatus (1) also comprises a non-destructive inspection station (2) that is positioned on the movement path (30), for carrying out a non-destructive inspection on the wooden board (9) that is supported by the chains or belts (32). The non-destructive inspection station (2) comprises at least one operating component (22) that is positioned on the same side as the chains or belts (32) and emits or receives a signal or an image, with an emission or reception field (220) that faces towards a region between two chains or belts (32). Each chain or belt (32) comprises an elongate flexible body (320) and at least one rest element (36) that is positioned on the elongate flexible body (320). The at least one rest element (36) projects upwards from the elongate flexible body (320) and has a top face (361) with a width (L36) that is less than the width (L32) of the elongate flexible body (320). The top faces (361) are intended to provide a surface on which the wooden board (9) can rest, so that the wooden board is kept at a distance from the elongate flexible body (320) of each chain or belt (32).

Abstract: A computer-implemented method to provide a cutting pattern for a tree log to obtain wooden boards including a step of obtaining a three-dimensional model containing information about features of a structure of the log and/or about defects of the log. A step of computer-processing of the three-dimensional model, to determine the cutting pattern by optimisation of an objective function, comprises the use of a value map to compute the value of a virtual board having a minor face with set orientation and set dimensions, at a cross-section of the three-dimensional model. The value map, which correlates to the information about the features and/or the defects of the log, assigns to each point of the cross-section a value of a virtual board having its minor face centred at that point and having the set orientation and set dimensions.

Abstract: Inspection of industrial products entails the “Model Based Design” paradigm with an apparatus associated with a digital clone of the real acquisition system. The digital clone reproduces in a virtual environment the features of said system and of the product affected by anomalies to be inspected.
By generating virtual images of the product through simulations on said digital clone and processing virtual images through a vision system including a novel data fusion module, it is possible to define the optimal architecture and parameterization of the real acquisition system that maximize the likelihood of identifying anomalies in products even in conditions that are difficult or expensive to replicate in the real world.
This reduces time in designing and set-up as well as costs of an inspection apparatus. Furthermore it enables to reconfigure the apparatus to products and/or anomalies other than those for which it was initially designed.

Abstract: A method and a related apparatus for performing a tomographic examination of an object (2) which advances through an examination area (6), wherein the examination area (6) is irradiated with x-rays transversally to a motion trajectory of the object (2) and the residual intensity of the x-rays which have crossed the object (2) is repeatedly detected to obtain, for each detection, an electronic two-dimensional pixel map, the two-dimensional maps thus obtained being processed by a computer to obtain a three-dimensional tomographic reconstruction of the object (2); wherein, during the advancement, the object (2) is made or let rotate, at least partly uncontrolled, in such a way that the object (2) rotates around one or more rotation axes which are transversal both to the motion trajectory and to the propagation directions of the x-rays crossing it; and wherein a computer also determines the spatial position in which the object (2) is located relative to the one or more emitters (4) and/or the one or more detectors (5) at the instant when each two-dimensional map is detected, and factors this in the tomographic reconstruction.
