lets say I have a photo that has a picture on a wall and a book upright on the desk. now i know the size of both of these objects. I want to find the distance between two of them on the photo, I was wondering if there were any guides or any good explanations on how to do this?
I plan to use this for a project app that slightly knows the location of an object(in a setroom) in an image by knowing the distance between object A(onthewall) and object B(somewhere randomly in the room) and the distance between object A and the camera.
sorry if the tags are quite right will fix them if you comment on it thanks for any advice
