1. A system that facilitates determination of the true inter-camera distance (TICD) between cameras mounted on separate portions of an articulated vehicle, comprising: a first camera; a second camera; and a processor configured to: receive from the first camera a first image frame comprising a first image of a reference object; receive from the second camera a second image frame comprising a second image of the reference object; overlay the first and second images thereby generating a composite image of the reference object; shift the first and second images until they are aligned; and calculate the TICD between the first and second cameras as a function of the distances by which first and second images are shifted during alignment, such that 
 TICD=(speed ratio*shift1)−(shift2)/(speed ratio−1) where shift1 is the amount by which the reference point or object in the image is shifted at a first speed, shift2 is the amount by which the reference point or object in the second image is shifted at a second speed, and speed ratio is the ratio of the second speed to the first speed.
