Camera set

[Dumeowmeow]

How can we adjust the camera parameters so that the rendered object stays the same size as the original image?

I had not much luck with that, check my ticket here: #107

So the extrinsic parameters of the output 3D asset are completely nondeterministic?

[marcok]

there are no extrinsic parameters, because there is no camera in the output to start with.

If you put a camera in the scene and lets say move it 100 units in Z direction, then yes the Object is from a more or less random perspective. Mostly the Top Down is consistent of same objects.
How the model works, this is also to expect actually.
