NAME
       linefind	- Detect vertical features in images

SYNOPSIS
       linefind	[options] -o output.pto	input.pto

DESCRIPTION
       linefind	is a detector for vertical features in images. It tries	to
       find vertical lines using the same algorithm as Calibrate_lens_gui and
       assigns vertical	control	points to them.	The detection runs on the
       source images, if the input images are rectilinear images. In the other
       cases (e. g. fisheye images) the	input images are reprojected to	an
       equirectangular projection and the detection works on the reprojected
       images. It uses the roll	value, saved in	the pto	project	file, to
       determine what is "top" and "bottom". So	before running linefind	check
       that your roll values are correct (E. g.	when using images straight
       from the	camera,	use a roll value of 0 for landscape and	a value	of 90
       or 270 for portrait images. If your camera has an orientation sensor,
       Hugin can detect	this information automatically and sets	the roll value
       accordingly when	adding such images into	Hugin.

OPTIONS
       -o|--output output.pto
	   Output Hugin	PTO file. Default: '<filename>_line.pto'.

       -l|--lines num
	   The maximum number of lines added per image (default: 5) Attention:
	   Keep	in mind	that more vertical control points will dominate	the
	   optimisation	in favour of "normal" control points.

       -i|--image num
	   Image number(s) to process.	Normally linefind tries	to find
	   vertical lines in all images	of the project file. If	you want to
	   limit the detection to some selected	images,	you can	use this
	   parameter. Can be used multiple times.
