Publication number: 20100182425Abstract: A vehicle interior state recognition device comprises an illuminating means for illuminating infrared rays into a vehicle compartment, an image pick-up means for picking up an image inside the vehicle compartment into which the infrared rays are illuminated by the illuminating means, and a recognizing means for recognizing specified information based on the image picked up by the image pick-up means. Objects of the image picked up by the image pick-up means include a seat which is movable relative to a vehicle body and a passenger seated in the seat, and the recognizing means determines a size of the passenger by comparing contour of the seat with contour of the passenger on the image picked up. Accordingly, the body size of the passenger seated in the seat can be determined accurately.Type: ApplicationFiled: November 20, 2009Publication date: July 22, 2010Applicant: MAZDA MOTOR CORPORATIONInventors: Masafumi SAKAKIDA, Toshihiko TOMITA, Mitsutoshi YAMANISHI, Keiko YAMANE, Tsukasa HARADA, Kazuhito HAYASHI
