spatialnde
----------

The purpose of this package is to facilitate data projection from
imaging NDE modalities (such as thermography) onto surface
parameterizations of CAD models.

It leverages the OpenCV package to do much of the real work
such as camera distortion correction and pose estimation

It is intended as a prototype. The successor package spatialnde2
should generally be used in most cases.
