FocalFromFundamental does not handle the case when optical centers converge (no result is possible)
Open, NormalPublic

Description

Steps to reproduce:

  1. Create a fundamental matrix corresponding to two cameras with crossing viewing directions.
  2. Call focal from fundamental

An assert fails because it tries to compute the sqrt of a negative number. The function should return some kind of error, so that the caller can do
something accordingly.
