A method for estimating the image depth map of a scene, includes the following steps: providing (E) an image, the focus of which depends on the depth and wavelength of the considered object points of the scene, using a longitudinal chromatic optical system; determining (E) a set of spectral images from the image provided by the longitudinal chromatic optical system; deconvoluting (E) the spectral images to provide estimated spectral images with field depth extension; and analyzing (E) a cost criterion depending on the estimated spectral images with field depth extension to provide an estimated depth map.

Determination of the image depth map of a scene

A method for calculating a depth map from an original matrix image, comprising the steps of: calculating a first matrix image corresponding to the original matrix image with a low resolution and in which the depth of field is similar to that of the original matrix image, calculating a second matrix image corresponding to the original matrix image with a low resolution, comprising a number of pixels similar to that of the first matrix image and in which the depth of field is greater than that of the original matrix image, implementing a DFD type three-dimensional reconstruction algorithm from the first and the second matrix images, outputting the depth map.
