Compute object distance in Image

HI,

I would know if any Matlab function allows me to compute the planar distance of an object from the camera.

In practice I want to replicate a navigation stadimeter, I want to estimate the distance of a ship from my camera.

As input to the function I can give:

• camera matrix (intrinsic, estrinsic, field of view,...)
• ship height

The problem would be trivial if the ship was exactly in the center of the image but my goal is to estimate the ships distance even in they are not centered (i.e. the camera is moving for waves).

Thanks

If you find a solution, please let me know as well.

How about imdistline ?
