ABSTRACT:
A vehicle occupant sensing system includes a plurality of image pickup devices arranged to capture a three-dimensional image in a region including at least a cover part of the front airbag system and an upper part of the front passenger seat, and a signal processing unit for processing image signals taken by the image pickup devices to determine a three-dimensional position of the captured image. The signal processing unit is configured to determine a three-dimensional position of a part of the captured image pertaining to the cover part and includes a storage section which stores in advance a reference three-dimensional position corresponding to an external configuration of the cover part, and a comparing section which compares the three-dimensional position of the image part pertaining to the cover part with the reference three-dimensional position to determine if there is an object placed on the cover part.
