Abstract
The invention relates to a method for measuring a distance between an object of a scene and a Time-Of-Flight camera system, and providing a depth map of the object, the Time-Of-Flight camera system comprising an illumination unit, an imaging sensor having a matrix of pixels and image processing means, the method being characterized by the following steps: modifying in a discrete way the illumination of said illumination unit in order to illuminate elementary areas of the scene with different incident intensities, respectively, for distinguishing the direct incident light beams from the indirect incident light beams; receiving onto the pixels of the matrix of the sensor the beams reflected by said elementary areas and providing the image processing means with corresponding data; processing the said corresponding data for eliminating the influence of the indirect light beams in the depth map of the object.
