Abstract

A method for producing and/or checking a part made of composite materials formed from one fabric having a surface whose texture exhibits a main orientation, including the following steps: obtaining a first image representing the texture of the fabric; determining an estimation relating to the main orientation of the texture, by determining for each pixel of the first image, an orientation of gradients relating to the luminance level of said pixel; determining an estimation of a global distribution of the orientations of gradients of the pixels of the first image; determining the main orientation as a function of the estimation of the global distribution of the orientations of gradients of the pixels of the first image; determining a deviation between the estimation relating to the main orientation and a setpoint value; and producing the part as a function of the deviation and/or emitting a check signal dependent on the deviation.

Dependent claims

A method for producing and/or controlling a part made of composite materials formed from at least one fabric having a surface whose texture has a main orientation, wherein it includes the following steps of:

obtaining a first image formed by a plurality of pixels and in which a luminance level can be determined for each pixel, representing the texture of the fabric;
determining an estimate relating to the main orientation of the texture:
during a first step, by determining, for each pixel of the first image, an orientation of gradients relating to the luminance level of said pixel;
during a second step, by determining an estimate of an overall distribution of the gradient orientations of the pixels of the first image;
during a third step, by determining the main orientation according to the estimate of the overall distribution of the gradient orientations of the pixels of the first image;
determining a deviation between the estimate relating to the main orientation and a setpoint value;
producing the part according to the deviation and/or emitting a control signal depending on the deviation.
