Segfault on Kermit Data - Eigen Empty Matrix error during Seam Levelling

[soulslicer]

Hi all,

I have compiled the latest master with RESEARCH off and DEBUG on. I have downloaded the kermit dataset which I have attached here (https://drive.google.com/open?id=0B2OqM2rPr8gEeXdnaWFvdDR6N1E).

I ran the following command:

./texrecon scene::undistorted kermit_surface_clean.ply textured

However, I received this segfault response with an Eigen Empty Matrix Error:

I have included my own dataset as well (https://drive.google.com/open?id=0B2OqM2rPr8gEYlFqTVdQMmlvdDQ)

Same error:

Seems to be happening during the adjustments stage in the global seam levelling step

Wow..turns out my transform matrix was inverted.

My transform was RGB to World. The system seems to want World to RGB.
