Door monitoring system and method

Abstract

A door monitoring system may include an image sensor that generates signals indicative of a field of view of the image sensors. The field of view may include an environment with a doorway region including at least a portion of a floor in proximity to a door of a vehicle. The system may also include a control circuit that obtains image data indicative of an image of the environment and identifies one or more background regions in the image. The control circuit further identifies a zone of interest, including at least a portion of the doorway region, in the image, and determines an amount of overlap of the one or more background regions with the zone of interest. The control circuit then determines the presence of an anomaly in the image based on the amount of overlap of the one or more background regions with the zone of interest.
