1. A method for augmenting a rearview display for a vehicle having a gate moveable between a closed configuration and an opened configuration, the method comprising:
collecting dynamic pixel images of an area behind the vehicle using a camera connected mounted on the gate of the vehicle, wherein the gate is a tailgate or liftgate, wherein the camera has a first perspective when the gate is in the closed configuration; and wherein the camera has a second perspective when the gate is in the opened configuration;
generating, via a processor, a projected path of the gate based on the first perspective when the gate is in the closed configuration;
receiving, via the processor, an input indicating the gate is in the opened configuration from a gate configuration sensor;
receiving, via the processor, a known location and pitch angle of the camera when the gate is in the opened configuration;
cropping, via the processor, the dynamic pixel images based on the known location and pitch angle of the camera to create a cropped image;
generating the projected path of the gate based on the second perspective when the gate is in the opened configuration; and
in response to a command, displaying a first graphical overlay to the dynamic pixel images on a display screen, via the processor, when the gate is in the closed configuration, wherein the first graphical overlay depicts an outline of the gate in the opened configuration, and displaying the first graphical overlay to the cropped image on the display screen, via the processor, when the gate is in the opened configuration.
