Question about the normsAll[c] during initialization

[Lurvelly]

Hi, Steffen

Thanks for your paper and code. But I have a question about the way to find the cam with most reconstructed points. It's easy to understand that the counter "nr_recon[c]" should bigger than the threshold "60", but why the middle norm "normsAll[c]" should bigger than 0.06 ? In my view, according to the bear1 cross product R*bear2 formula( bear1 x (Rbear2)), we can get a normal perpendicular to vector "bear1" and "Rbear2", and the norm of the normal is positive correlation with the area between two vector. So I think the norm smaller, the rotation "R" will be more accurately, isn't it?
