A vehicle restraint system has a vision-based occupant classification
system for control of airbag deployment during a crash scenario. The
classification system utilizes two imaging sensors which together create
a stream of paired images received and stored by an occupant
classification controller. A computer program product of the controller
utilizes the paired images to extract disparity/range features and
stereo-vision differential edge density features. Moreover, the
controller extracts wavelet features from one of the two paired images.
All three features or maps are classified amongst preferably seven
classifications by algorithms of the computer program product producing
class confidence data fed to a sensor fusion engine of the controller for
processing and output of an airbag control signal input into a restraint
controller of the vehicle restraint system.
