Classification system and method using relative orientations of a vehicle occupant
First Claim
1. A method of using a visual image acquired by a sensor to classify a vehicle occupant in a vehicle safety restraint application, the method comprising:
- generating an initial classification of the vehicle occupant;
identifying a relative orientation of the vehicle occupant in relation to a predefined reference; and
generating a weighted classification of the vehicle occupant based on said initial classification and said relative orientation.

Abstract
The present invention relates in general to systems and methods for classifying target information acquired with a sensor. In particular, the systems and methods relate to integrating relative orientations of the target information into evidential reasoning heuristics that are used to classify the target information. An exemplary system for classifying target information includes: an initial classification subsystem for determining an initial classification of the target information; a tracking subsystem for identifying a relative orientation of the target information in relation to a predefined reference; and a weighted classification determination subsystem for generating a classification of the target information based on said initial classification and said relative orientation.

15. A method of implementing an occupant classifier for use in a vehicle safety restraint application, comprising:
-
configuring a tracker to use a visual image to identify a relative orientation of a vehicle occupant in relation to a predefined reference;
implementing a weighted classification heuristic configured to generate a weighted classification of the vehicle occupant based on historical classification attributes that are configured to be influenced by said relative orientation and an initial classification of the vehicle occupant;
defining a group as a disablement decision; and
configuring the vehicle safety restraint application to preclude deployment of a safety restraint device when said weighted classification indicates that the vehicle occupant is classified as said group. - View Dependent Claims (16, 17)
