Abstract: PURPOSE: A method for applying an occupant classification system and type grade to an occupant image is provided to perform timely and exact grade decision and to minimize resources for the classification system with increased efficiency. CONSTITUTION: A method for applying an occupant classification system and an occupant type grade(48) to an occupant image determines whether a collision occurs, whether an airbag is deployed, and what the desirable strength of an airbag deployment is based on occupant characteristics obtained from a segmented image(38) of the occupant. Using interacting multiple model filters, the method infers three-dimensional characteristics from a two-dimensional image and predicts the location, velocity, and the acceleration of the occupant. The filters are used with respect to all measurements to incorporate past predictions and measurements into the most recent estimates and predictions to eliminate the noise associated with any particular measurement. The system predicts the position and shape of the occupant at a faster rate than the rate at which a sensor collects data. Occupant characteristics are compared to corresponding predetermined data associated with various occupant modes, including the mode of crashing, to determine if the collision occurs.
