Abstract

A vehicle includes a vehicle body defining a cargo area, a display mounted to the vehicle, a first video camera and an image processor. The first video camera is fixedly mounted to the vehicle at a first fixed location in a prescribed orientation relative to the vehicle to capture a video image of the cargo area. The image processor is operatively coupled to the first video camera and the display to process the video image captured by the first video camera and to stream a simulated video overhead view including at least a portion of the cargo area on the display.
