The invention is a
system and method that detects
seat belt-related features using an
image sensor. Reflective materials are optionally applied onto or embedded into the
seat belt webbing, buckle,
nest and
handle to reflect patterns from
infrared illumination to the
image sensor.
Software compounds these findings to result an overall ‘Belted’ and ‘Unbelted’ detection output. A temporal model
software assists in stabilizing the decision in unsure situations by adding past images' decisions into the current decision. ‘Twisted belt’ and ‘
Seat belt buckled behind back / seat’ situations can be also detected to notify the driver about unsafe occupant situations in the vehicle. The detection is applicable to safety belt detection for the driver seat, front passenger seat, back or any additional seats in vehicles.
