Abstract (en)

[origin: WO2022253925A1] The invention relates to a method for capturing images of a first surface (12) of a human body using an imaging device (20) comprising a lens (40) with variable focal length, said method comprising the steps of: - capturing a plurality of images using the imaging device (20), said capturing being carried out by varying the focal length (df) of the lens (40) with variable focal length according to a control law; - constructing a sharp image of a portion of the surface (12) of the human body from the plurality of captured images of said surface (12); and - estimating the depth map of the local geometry of the first surface (12).
