# How to determine the angle a camera has to be at to image a desired scene, given the camera parameters?

Reviewing old material I learned years ago, having a hard time rewrapping my head around the relationships in capturing images from a camera.

Imagine a scenario with the camera placed on the ground (potentially elevated at some angle). We have a sensor size of 3.6 by 4.8 mm, a resolution of 640 x 480 px, a 10 cm tall object that we want to be 50 px in the image. We have a focal length of 3 mm and the image is 1 m away.

How do we determine the angle that the camera has to be at to capture the image with these properties?
