Claim 5:
6. A method for determining a depth map of a scene, the method comprising:
generating, at a time of flight sensor, a distance map of a scene, the time of flight sensor being configured to generate a corresponding distance histogram for each acquisition zone of the scene; and
acquiring, at a stereoscopic image acquisition device, two images of the scene from two different viewpoints;
identifying, at the stereoscopic image acquisition device, regions of a depth map to be generated from the two images that corresponds to the distance map;
generating, at the stereoscopic image acquisition device, a range of values of disparities, region by region, from extreme values of the distances of the corresponding histogram; and
extrapolating, at the stereoscopic image acquisition device, distances of the scene from the disparities between the two images, wherein, for each region, the extrapolating of the distances of the scene is performed based on the range of values of the disparities for a corresponding region.
