THREE-DIMENSIONAL RECONSTRUCTION PROCESS WITH AID OF A PLENOPTIC CAMERA

摘要

The present invention relates to a three-dimensional reconstruction process of a surface of interest (200). with the aid of a plenoptic camera (100) comprising the following steps: - determining the three-dimensional coordinates of a series of points in the object field of the plenoptic camera, said sampling points (pj); - determination of calibration data,associating to each sampling point (pj) at least two pixels (pk) of the matrix optical sensor; - definition of a reconstruction grid,of which each point is associated with one or more sampling points (pj); - acquisition (401) of at least one image of the surface of interest with the aid of the plenoptic camera (100); - from the calibration data and surface image of interest,calculation (402), for each point of the reconstruction grid, of the value of a dissimilarity index (cn), function of one or more dispersion (s), each dispersion being representative of a gap between the intensity values ​​taken, in the image of the surface of interest, by the pixels associated with one of the corresponding sampling points (pj); - determination (403) of a three-dimensional distribution of the points of the reconstruction grid,each coated with its dissimilarity index (cn) value; - three-dimensional reconstruction (404) of the surface of interest.
