Confidence boost for automotive occupant classifications
First Claim
1. A method of classifying an occupant of a motor vehicle, said method comprising the steps of:
- processing a plurality of image frames to detect an occupant;
categorizing the occupant into one of a plurality of static categories, each of the static categories including at least one class indicative of at least one of an occupant type and a position in the vehicle; and
classifying the occupant into the at least one class, wherein the step of classifying includes determining a spatial confidence having a consistency over a predetermined period of time, and observing the consistency of the spatial confidence over the predetermined period of time to establish a temporal confidence.

Abstract
The present invention relates to systems for determining the position and the type of an occupant in a vehicle. More specifically, the present invention provides an occupant position and type classification system including an occupant detection module, a processor in communication with the occupant detection module, and memory accessible by the processor and storing program instructions executable by the processor to perform the steps of categorizing the occupant into one of a plurality of static categories, each of the static categories including at least one class indicative of the occupant'"'"'s type or position in the vehicle, and classifying the occupant into one of the classes.

8. An occupant position classification system, said system comprising:
-
means for capturing a plural of image frames; a processor in communication with said means for capturing the image frames; and memory accessible by said processor and storing program instructions executable by said processor to perform method steps, the method steps comprising; processing the plurality of image frames to detect an occupant; categorizing the occupant into one of a plurality of static categories, each of the static categories including at least one class indicative of at least one of an occupant type and a position in the vehicle; classifying the occupant into the at least one class; determining a spatial confidence distribution pattern of each of the plurality of image frames; and determining a temporal distribution pattern of each of the plurality of image frames over a predetermined number of consecutive image frames, wherein the program instructions are executable by said processor to perform a step of defining a confidence condition, the confidence condition indicating a desired accuracy in the classification of the occupant into the at least one class. - View Dependent Claims (9, 10, 11, 12)
