Detailed Documentation

Bundle adjuster that expects affine transformation represented in homogeneous coordinates in R for each camera param. Implements camera parameters refinement algorithm which minimizes sum of the reprojection error squares.

It estimates all transformation parameters. Refinement mask is ignored.
