<p>Method of acquiring and processing images for the detection of the motion of at least one target in a scene, comprising the following steps: acquisition of primary maps (CP) of depth of the scene at successive time intervals by means of a source and of an infrared sensor; acquisition of primary images (IP) of the scene at successive time intervals by means of a camera (3); determination of secondary maps (CS) of depth by suppression of a reference background of the scene on each primary map; temporal synchronization of the secondary maps and primary images; superposition of the secondary maps and synchronized primary images so as to obtain secondary images (IS) comprising pixels integrating colour data and field depth data for the targets present in the scene outside of the reference background; comparison of the successive secondary images so as to detect the motion of the target or targets present in the scene.</p> |
