Hi, generally I use a local reference frame which can be easily related to the geographic one. For instance if the model extension is of some hundredth of meters you can take your UTM coordinates and cut the first digits, those referring to kilometers, and leave just those referring to meters. In this way if UTM is E = 345678.123 N = 5978123.345 Z = 123.456, you get X = 678.123 Y = 123.345 Z = 123.456 in your local system, and you can always go back to the full UTM coords if you need. Changchang, does this make sense to you? And more important: I georeference with respect to this local system before generating the dense reconstruction, in order to get also the photo positiotion and orientation in the camera_v2.txt in the same system. Do you see any problem with this workflow?
