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. fish-
     eye images) the input images are reprojected to an equirectangular projec-
     tion 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 "bot-
     tom". 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 opti-
	 misation 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 de-
	 tection to some selected images, you can use this parameter. Can be
	 used multiple times.
