Human posture estimation using voxel data for "smart" airbag systems: issues and framework

This paper examines the feasibility of a multi-camera voxel based occupant posture estimation system. Several new considerations are made to allow this tested human body modeling system to work reliably in the passenger seat of a vehicle, including camera position, segmentation, and body modeling with voxel reconstructions all from a constrained 4 camera setup. To describe occupant posture, a partial human body model consisting of a head and torso is proposed. The accuracy of the estimation of this model is compared against ground-truth.
