Method for automatically searching for at least one textile pattern in a composite material reinforcement

A computer implemented method for automatically inspecting the textile geometry of a reinforcement of composite material including a plurality of textile patterns, each textile pattern comprising a plurality of reinforcing yarns arranged according to a textile topology, the method comprising:

• reconstructing the textile geometry of the reinforcement of the composite material, which comprises searching, using an artificial neural network trained, in a supervised manner, on a training database to detect the given textile pattern in a three-dimensional image of the reinforcement of composite material, for the given textile pattern in the three-dimensional image acquired, the training database including, for each training composite material of a plurality of training composite materials, a three-dimensional image of the reinforcement of the training composite material, and for each textile pattern to be detected, the textile topology of the textile pattern and the location of the textile pattern in the three-dimensional image, and comparing the reconstruction of the textile geometry of the reinforcement of composite material with a theoretical textile geometry.
