Abstract
A protective warning system for a vehicle is provided. A device comprises: a long-range camera and a stereoscopic camera positioned in a housing to image external objects in a rear-facing direction when the housing is mounted to a vehicle. A controller detects, using images from the long-range camera, an external object in the rear-facing direction and processes stereoscopic images from the stereoscopic camera to determine when the external object is located within a first zone or a second zone extending in the rear-facing direction, the second zone being closer to the stereoscopic camera than the first zone. In response to determining that the external object is located within the first zone or the second zone, the controller controls the one or more notification devices to provide one or more first or second notifications associated with a first or second urgency level.
