I have n points of interests (POIs).
I have a local coordinate system. For all these n POIs I know there position in this system, that is there x, y, z translation (local position) from origin of this system in metres.
I also know the lat, lng, z (global position) in WGS-84 of all these POIs.
How can I estimate the (lat, lng, z) of the origin of this local system by using the POIs?
If I understand correctly I need atleast 4 POIs to do this as I have 3 unknowns the translation and the orientation angle. Dont I?
