Abstract
Analysis of the vehicle occupant posture is a key problem in designing "smart airbag" systems. Vision based technology could enable the use of precise information about the occupant's size, position, and posture in making airbag deployment decisions. In this paper, experiments are presented in estimation of the body posture of a sitting person using a motion capture system that performs analysis of voxel data. The report will show that this system is capable of extracting posture of the body and the head with good accuracy.
