In order to provide a technology which is effective for easily and precisely detecting information about an object (C) seated in a vehicle seat (12), a detection system is developed for a vehicle. The detection system comprises a photographing means (110) for detecting a three-dimensional surface profile of a vehicle occupant (C) relating to a single view point, a digitizing means (130) for digitizing the three-dimensional surface profile thus detected, a seat cushion height detector (142), a seat back inclination detector (143), a seat slide position detector (144), a plane setting unit (145), a volume calculating unit (146), and a body size determination unit (147). The seat cushion height detector (142), the seat back inclination detector (143), and the seat slide position detector (144) detect information about condition of a vehicle seat. The plane setting unit (145) sets reference planes which define the profile of the far side, i.e. a side invisible from the single view point, based on the information about the seat condition of the vehicle seat. The volume calculating unit (146) and the body size determination unit (147) correct the digitized coordinates, which are digitized by the digitizing means (130), by the reference plane, which was set by said reference plane setting means (145), and derive the information about the vehicle occupant (C) from the digitized coordinates thus corrected. |
