Aligning chunks

Each zone is processed separately in Metashape, in its own chunk (a set of photos processed on its own), and every model comes out of the process slightly distorted. These distortions make it hard to line the models up with each other.

The size has to be right too: a model that isn’t exactly to scale won’t line up with its neighbours. So I used targets to set measuring scales on each model and bring it to its exact real dimensions.

The distortion itself isn’t fully solved yet: see Banana effect.
