Detailed Description

The 3-d offset and scale parameters of rational cameras typically must be adjusted to compensate for errors in geographic alignment.

This algorithm adjusts these parameters to give the smallest projection error. That is, the error between the true image location and the projected 3-d world point corresponding to that location.
