Abstract
Disclosed is a method intended to validate that an element is covered with a true skin and implemented by a validation device including a light source at at least one wavelength, a sensor, an analysis module and a decision-taking module. The method may include: placing a surface of the element in front of the light source and the sensor; illuminating, by the light source, the surface of the element; capturing, by the sensor, for each wavelength, an image of the positioned element that encompasses an illuminated zone of the element directly illuminated by the light beam and a peripheral zone (“the diffusion zone of the element,” which is peripheral to the illuminated zone); analyzing the illuminated zone and the diffusion zone of the captured image; and deciding, by the decision-taking module, whether the element is covered with a true skin according to the results of the analysis.
