We are trying to use Unreal Engine for computer vision experiments and for this we need to know focal length of the camera. The questions we have are,
- How do you computer focal length from field of view in Unreal Engine?
- Is FOV in Unreal Engine horizontal or vertical?
- Is this computation different for Camera component vs SceneCapture2D component?
- Note that SceneCapture2D doesn’t have aspect ratio. Does this mean we can set any aspect ratio we like?
