LINEFIND(1) HUGIN LINEFIND(1)NAMElinefind - Detect vertical features in images
SYNOPSISlinefind [options] -o output.pto input.pto
DESCRIPTIONlinefind 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.
