Title:
METHOD AND SYSTEM FOR SKELETONISING THE STRANDS OF A COMPOSITE MATERIAL PART IN A 3D IMAGE
Document Type and Number:
WIPO Patent Application WO/2021/197813
Kind Code:
A1
Abstract:
A method for skeletonising the strands of a composite material part in a 3D image (V) comprising a step of detecting oriented section centres of the strands and a link (EL) from each centre to the closest centre having the same orientation, the detection being carried out by means of at least one reference volume comprising an oriented centred strand pattern, the detection step comprising, for each reference volume: • a step of determining portions of the image (V), • a step of calculating a correlation score between the reference volume and each portion associated with the central voxel of each portion, so as to obtain a correlation score for each voxel of the image (V); and • a step of determining the strand centres corresponding to the voxels having a correlation score which corresponds to a local maximum.
