1. A method of calibrating multiple image capture devices of a vehicle, the method comprising the steps of: providing a plurality of image capture devices having different poses, at least one of the plurality of image capture devices being identified as a reference device; capturing an image of a patterned display exterior of the vehicle by the plurality of image capture devices, the patterned display including multiple landmarks of known positions, each image capture device capturing at least a portion of the patterned display; traversing the vehicle across the patterned display to capture images at various instances of time by the plurality of image capture devices; identifying, by a processor, common landmarks of the patterned display between each of the images captured by the plurality of image capture devices and the reference device; stitching images of the patterned display captured by each of the plurality of image devices using the identified common landmarks; and adjusting extrinsic parameters of each image capture device relative to the reference device based on the stitched images for calibrating the plurality of image capture devices.
