Providing new generations of airbags with reliable information about the vehicle inner space occupancy in order to minimize inappropriate inflation is a real challenge. Two techniques to rebuilt the 3D (Three-Dimensional) cockpit scene, are presented; beside the well-known stereoscopic vision principles, 3D reconstruction based on matricial sensor combined with an infrared structured light emitter is described. From the 3D points acquired by these sensors a 3D description of the seat area is built, pertinent attributes are extracted, and using a previously learnt data base, the current seat situation is identified amongst the learnt situations (empty seat, baby seat in normal or rear position, occupant, etc.). First promising results are depicted.
