Abstract: 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.

Abstract: Method, having detecting from a first histogram signal delivered by a sensor device, successive sets of targets at respective successive instants, determining for a current set of current detected targets, a current histogram output, the current histogram output having for each current detected target of the current set, a current group of parameters stored in a memory including a confidence indicator, performing a matching operation between the current set of detected targets and previous sets of detected targets stored in the memory, and performing a filtering operation of at least one parameter of the current group of parameters of at least some of the current detected targets of the current set, on the basis of the result of the matching operation, the filtering operation being weighted on the basis of at least the confidence indicators of current and previous sets of detected targets.
