Abstract: The disclosure relates to a method for reconstruction of a three-dimensional image of an object. A first image is acquired of the object lit by a luminous flux having, in a region including the object, a luminous intensity dependant on the distance, with a light source emitting the luminous flux. A second image is acquired of the object lit by a luminous flux having, in a region including the object, a constant luminous intensity. For each pixel of a three-dimensional image, a relative distance of a point of the object is determined as a function of the intensity of a pixel corresponding to the point of the object in each of the acquired images.
