Title:
  calibrate_lens_gui: allow crossing lines to be detected?

Status in Hugin - Panorama Tools GUI:

Status in “hugin” package in Ubuntu:

Bug description:
  Is it possible to tweak the line-detection algorithm (possibly
  optionally) to recognise straight lines that form a grid?

  I took a series of photos of a building which I thought would be great
  for lens calibration, since it consists of pale panels with dark
  gridlines in between (much-reduced photo attached); however,
  calibrate_lens_gui breaks the detected lines where they cross each
  other, so none of the lines ends up very long, and it doesn't derive
  good calibration values.

  (This is with the version that comes with Ubuntu 12.04, which is based
  on 2011.4.0; I haven't tried the latest version, but I've found no
  indication that this has been worked on. Sorry if you have already
  done this.)
