摘要： The invention relates to a method for characterising a part made of a woven composite material, wherein said method includes calculating (200) autocorrelation values of a three-dimensional image in an observation window of the volume of the part, for a plurality of spatial vectors used as an autocorrelation interval, followed by detecting (400, 410) at least one local extremum of the autocorrelation value in a main weaving direction in order to determine an average distance between adjacent parallel threads in the observation window. X-ray tomography is preferably used to image the material.

摘要： The invention relates to a method of non-destructive checking of a component for aeronautics, the method comprising the following steps of acquiring a volume by tomographic imaging, of generating by computer simulation a surface corresponding to the component to be analysed, of registering the volume and the surface (by optimizing a similarity criterion defined by a function taking into account the correlation between normal vectors of a field of normal vectors of the surface displaced by transformation and a gradient of a gradient field of the volume, said optimization being performed as a function of transformations for determining the optimal transformation which maximizes the similarity criterion, of storing the optimal transformation, of establishing the correspondence between the surface and the volume obtained with the aid of the optimal transformation.

摘要： The invention concerns a method and a system for non-intrusively measuring the volume density of a specific phase in a part, comprising: - processing means (9) for producing a three-dimensional image (17) of said part (11), said image being formed by a three-dimensional grid of voxels of which the values indicate the arrangement of said specific phase in said part, - processing means (9) for associating a binary coefficient with each voxel of said three-dimensional image, thus constructing an initial three-dimensional matrix representation of binary coefficients, said binary coefficients being representative of a presence or absence of said specific phase in areas of said part corresponding to the voxels, - processing means (9) for convolving said initial matrix representation with a matrix convolution kernel corresponding to a predefined reference volume, said convolution being performed by implementing a composition of three (successive) one-dimensional convolutions in three separate directions, thus forming a resulting matrix representation of which each resulting coefficient represents a volume level (density) of said specific phase in said reference volume.
