METHOD FOR CONSTRUCTING A DEPTH MAP OF A SCENE AND / OR A COMPLETELY FOCUSED IMAGE

摘要

The invention relates to a method of generating, by means of a processing device (109), a depth map and / or a fully focused image of a scene (105), from a series images of the scene taken under the same angle of view but with separate focus, this method comprising the following steps: a) for each pixel position in the series of images, search for an extremum of the pixel value in the series of images; and b1) assigning to said pixel position a rank-dependent depth value, in the series of images, of the image in which the extremum has been identified in step a) so as to construct a depth map of the scene, and / or b2) assigning to said pixel position the value of the extremum identified in step a) so as to construct a fully focused image of the scene.
