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.
