2D to 3D Camera Angle Compare

I have a couple 2D images of a 3D environment and would like to be able to check them for consistency. I am not sure that I have placed all the objects in the same location. What I would like to do is find a way to compare the images from different camera angles and check to see if they are consistent. Help, insight, or next steps would be much appreciated.

Sorry if this is a little off topic or basic, but I could really use some help.

Well, I can’t help you much, but I think the field you’re interested in is computer vision. Intel’s OpenCV (for Computer Vision) is an api designed to help you. Maybe you can check it out.
