Abstract
Method and system for non-intrusive measurement of volume density of a specific phase in a part, comprising: processor producing a volume image of the part, the image being formed by a three-dimensional grid of voxels, the values of which indicate the disposition of the specific phase in the part, processor associating a binary coefficient with each voxel of the volume image, thus constructing an initial three-dimensional matrix representation of binary coefficients representing a presence or absence of the specific phase in zones of the part corresponding to the voxels, processor convoluting the initial matrix representation with a convolution matrix kernel corresponding to a predetermined reference volume, the convolution performed by effecting a composition of three (successive) monodimensional convolutions in three independent directions, thus forming a resultant matrix representation, each resultant coefficient of which represents a volume ratio (the density) of the specific phase in the reference volume.
