Hi! let's say i have a 2d image of a place. I'd like to obtain the camera position that give that perspective, so that i can render 3d object over it.
Here's an example of this:

Is there a math approach ? For example i give the (2d coors, 3d coords) couples and it tells me the campera pos/rot ?

Thanks!
