Used this pretty extensively, and followed their dev branches. FWIW if you want quality results the best option is Agisoft, on a GPU machine w/ some custom python to automate.
FWIW, ODM was slightly better quality than Photoscan in our tests. We only tested orthomosaics but ODM had less error to our ground control points (note we didn't feed the givens into these tests) and less aberrations.
