Public bug reported:
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.)
