Patent attributes
Described herein are systems, methods, and computer readable media for capturing image data of one or more regions of a vehicle (e.g., a cargo area of an autonomous vehicle) at various particular times and assessing the image data to determine whether a past vehicle occupant has left behind one or more belongings of value in the vehicle. If it is determined that a former vehicle occupant has left behind an article of value, an audible message may be outputted from a speaker of the vehicle to inform the former occupant of the presence of the article in the vehicle or a notification may be sent to a mobile device of the former occupant. The audible message may be outputted, for example, while the former occupant is beyond a predetermined distance from the vehicle, but still within range of hearing the message.
