The invention relates to a method for estimation of information representative of a height. In order to minimize the required calculation time, the method comprises steps for:
- selection of a first point from among a plurality of points of a normal map, a normal being associated with each of the points of said plurality, a reference height being associated with said first point,
- estimation of a height difference between the first point and a second point of the normal map different from the first point (P1) according to the normal (302) associated with the second point (P2) and the distance (3011) separating the first point (P1) from the second point (P2) in the normal map. |
