1. An image processing system for generating a display for a vehicle, the image processing system comprising:
at least one processor configured to execute program instructions, wherein the program instructions are configured to cause the at least one processor to:
receive images, respectively, from a plurality of cameras mounted on the vehicle, wherein the field of view of the plurality of cameras at least partially overlap, and wherein the field of view of at least one the plurality of cameras includes a region underneath the vehicle;
transforming the images to a common reference plane using a perspective transformation algorithm and based on intrinsic and extrinsic parameters of the plurality of cameras, to thereby obtain a projected image, wherein the projected image is projected to the common reference plane; and
generating the display based on the projected image, wherein the display includes a synthetic depiction of the vehicle including an outer profile and at least one range ring around the outer profile and wherein the display incudes an image area within the outer profile that is based on the projected image for the region underneath the vehicle,
wherein each of the at least one range ring is spaced and disposed at a set distance away from the synthetic depiction of the vehicle.
