reverse info of camera distance & angle from still frame?

[vonkuttenberg]

hello guys, is there any way how to count reversely from vanishing points & horizont a distance of the camera & camera angle (& lense)? i am going to shoot some greenscreen stuff for this picture ... thnx for info

i would like to know where to position the camera and what angle.

i am wondering about that when the vertical lines are straight up, that means that the camera is flatlings ahaed (0°), when they meet upwards mean that the angle is <0° (camera looking down) and vice versa >0°? but is there any way how to count more precisely?
