A vehicle interior monitoring system to identify, locate and monitor
occupants, including their parts, and other objects in the passenger
compartment and objects outside of a motor vehicle, such as an automobile
or truck, by illuminating the contents of the vehicle and objects outside
of the vehicle with electromagnetic, and specifically infrared, radiation
and using one or more lenses to focus images of the contents onto one or
more arrays of charge coupled devices (CCD arrays). Outputs from the CCD
arrays are analyzed by appropriate computational means employing trained
pattern recognition technologies, to classify, identify or locate the
contents or external objects. In general, the information obtained by the
identification and monitoring system is used to affect the operation of
some other system in the vehicle. When system is installed in the
passenger compartment of an automotive vehicle equipped with an airbag,
the system determines the position of the vehicle occupant relative to the
airbag and disables deployment of the airbag if the occupant is positioned
so that he/she is likely to be injured by the deployment of the airbag.
