All,
I am looking into use of Structure from Motion systems (e.g. http://homes.cs.washington.edu/~ccwu/vsfm/) to turn old standard photographs into historical terrain surfaces, and possibly for geospatial 3d documentation of complex habitat structures.  Several of the available systems output XYZ coordinates in arbitrary coordinate systems.

I'm wondering if there are already any functions available in R to transform those arbitrary-coordinate point clouds into real-world coordinate systems such as UTM?

Furthermore, when constructing DTMs, I suspect that the SfM systems might have some slight curvature as an artifact of lens distortion, particularly when only a couple, very oblique images are available to work with (though my initial trials "look" quite good).  So functions with some warping capability (polynomial?) would be preferred.

Thanks,
---
