Using MATLAB to scale an image. Searching for unknown dimensions based on known dimensions

Jordan Schroeder on 21 Mar 2022

I want to scale A and B (shown in a picture below) from a known dimension (base of tail light) from an image of an assembled car. The purpose is to get factory dimensions prior to welding my car together because I replaced both quarters, trunk pan, and trunk drop-offs. I replaced the frame rails. I made tubular ones in an effort to make them stronger. The installation of the tail panel will tie everything together. I want to make sure it's right.
