3D Reconstruction with uncalibrated cameras

I'm working on my degree thesis, regarding Dense Stereo 3D Reconstruction.
As of now, I've written a GUI that lets the user select two images (left and right stereo pair) and rectify them by manually inserting corresponding points. Since I'm working with very old stereo photos, I don't know anything about the camera specs, and I have to assume that the photographer used different cameras during his work. This means that the Rectifying algorithm I used is an uncalibrated one.
The rectified images are then used to calculate a disparity map using OpenCV stereoBM (or different algorithms).
Now, I need to find a way to reconstruct a 3D scene using the disparity map I got. I don't think I can use reconstructScene, because, as I've said, I have no camera parameters.
Do you guys have any advice on what to do?
Thanks in advance for your answers.

Do you have any additional information in the scene, e.g., parallel lines, parallel planes, etc...?
