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 1):
A device for capturing an image of a print of a body part, comprising an image-acquiring module having an optical field covering an acquisition zone through which the body part may move, a light source that produces a spatially uniform illumination of the body part and a sight-projecting module that projects a luminous sight onto said body part perpendicularly to a direction of movement of the body part, wherein:\n the luminous sight is a repetitive pattern of lower light intensity than the uniform illumination; and said device comprises circuitry adapted to: simultaneously activate the light source, the sight-projecting module and the image-acquiring module in order to allow an image of the imprint, called the acquired image, to be acquired; 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; generate 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 to subtract 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.
