The method of determination of a depth map of a scene comprises generation of a distance map of the scene obtained by time of flight measurements, acquisition of two images of the scene from two different viewpoints, and stereoscopic processing of the two images taking into account the distance map. The generation of the distance map includes generation of distance histograms acquisition zone by acquisition zone of the scene, and the stereoscopic processing includes, for each region of the depth map corresponding to an acquisition zone, elementary processing taking into account the corresponding histogram.

A method for acquiring tracking points belonging to a trajectory of a target object in motion, includes: emitting a radiation towards the target object; receiving a reflection of the radiation from the target object in respective fields of view of each detection zone of a network of detection zones; processing the reflection by determining distances separating the target object from an origin point by measuring a time of flight of the radiation in each detection zone; determining a degree of coverage of each detection zone; and estimating, based on the distances and on the degree of coverage of each detection zone, a position of a tracking point corresponding to a position of an extremity of the target object inside a respective detection zone chosen in a direction of motion of the target object.
