Abstract
A method for acquiring images of a first surface of a human body using a image capturing device including a variable focus optics, the method including acquisitions of a plurality of images using the image capturing device, the acquisitions being carried out by varying the focal length of the variable focus optics according to a control law; constructing a sharp image of a portion of the surface of the human body from the plurality of images acquired of the surface, and estimating the depth map of the local geometry of the first surface.

A method for acquiring images of a first surface of a human body using an image capturing device comprising a variable focus optics, said method comprising:
- acquiring a plurality of images using the image capturing device along a processing trajectory on the surface of a human body;
- successively acquired images comprising among themselves a coverage rate of a portion of the surface of the human body;
- said acquisitions being made in a plurality of positions with respect to the surface of the human body and by varying a focal length of the variable focus optics according to a control law taking account of a measured or estimated distance between the variable focus optics and a first point of the processing trajectory, and
- constructing a sharp image of a portion of the surface of the human body from the plurality of images acquired of said surface including at least two images successively acquired by the image capturing device in two different acquisition positions with respect to the surface of the human body and comprising a coverage rate among them.
