Abstract

The invention relates to a method for determining depth information of a scene facing a vehicle. Upon obtaining (500) a representative image of the scene, a light intensity map (501) is generated from a generation model, the light intensity map corresponding to a light pattern. The determined light intensity map is transmitted (502) to a light module for projection (503) of at least one pixelated light beam, according to the light pattern corresponding to the generated light intensity map, onto the scene facing the vehicle. Upon obtaining (504) at least one first representative image of the scene facing the vehicle, following the projection of at least one pixelated light beam according to the light pattern, the method comprises determining (505) depth information of the scene facing the vehicle from at least one first image obtained.
