Abstract:
A device for capturing imprints of a body part on-the-fly, including a stand which includes a region of free space through which a user may pass a body part. When in this zone, the body part is simultaneously illuminated by a light source that produces a uniform illumination of the body part and a sight-projecting module that projects a sight onto the body part, and an image of the body part thus illuminated is acquired by the image-acquiring module. The capturing device is able to model the variations in light intensity of the projection of the sight on the body part by determining parameters of a preset parametric mathematical model, and generate a synthetic image of said projection on the basis of said model and using parameters determined beforehand. The synthetic image is then subtracted from the acquired image in order to obtain a sight-free image of the body part.

Claim (Index 7):
An authenticating or identifying method, comprising:\n obtaining an image, called the acquired image, resulting from simultaneous activation of a light source, of a sight-projecting module and of an image-acquiring module in a device for capturing an image of a imprint of a body part, said image-acquiring module having an optical field covering an acquisition zone through which the body part may move, the light source producing a spatially uniform illumination on the body part and the sight-projecting module projecting a luminous sight onto said body part perpendicularly to a direction of movement of the body part, the luminous sight being a repetitive pattern of lower light intensity than the uniform illumination; modelling the variations in light intensity of the projection of the sight on the body part by determining parameters of a preset parametric mathematical model; generating an image of the projection of the sight on the body part, called the synthetic image, on the basis of said model and using the parameters determined beforehand, and subtracting the synthetic image from the acquired image in order to obtain a sight-free image of the body part, said sight-free image of the body part being able to be used to carry out an identification or an authentication.
