Align reconstructed surface on camera frame

[GRicciardi00]

Hello,
First of all, thank you for the fantastic work you're doing with this amazing application.
I attempted to reconstruct an object and now I want to align and possibly overlay it on the real object in the camera frame. My plan is to use the features extracted during the reconstruction and match them with new ones calculated in real-time from the current camera frame.
In my example, I'm using DSPSIFT for feature extraction. I would like to know how to access these features and would appreciate any tips or sources of inspiration for implementing my solution, preferably using Python.
