Dumb question: could you not simply include an object in the scene that is of known dimensions and use that to calibrate scale?

- zo1 7y agoYes, you definitely could? Not sure for this piece of software specifically though. But for land-based photogrammetry in general, they usually use known control-points that have fixed 3d coordinates attached to them in order to calibrate their models. They also use that to effectively "tie" the resulting model to an actual location on the map.
