NAME

6       ptoclean - prune improbable control points
7

SYNOPSIS

9       ptoclean [options] --output better.pto notgood.pto
10
11        Options:
12         -o | --output     Filename of pruned project (can be the the same as the input)
13         -n | --amount     Distance factor for pruning (default=2)
14         -f | --fast       Don't run the optimiser for each image pair (similar to APClean)
15         -v | --verbose    Report some statistics
16         -h | --help       Outputs help documentation

DESCRIPTION

19       ptoclean takes a hugin .pto project and removes inconsistent control-
20       points.  'Bad' points are determined by calculating the average error
21       distance and standard deviation (Sigma), then removing any points with
22       an error distance greater than the average by n * sigma.  This pruning
23       is performed on each pair of images in turn and then finally on the
24       project as a whole.
25
26       Additionally the autooptimiser tool is run on each pair of images
27       separately before each calculation, so there is no need for the project
28       to be 'nearly aligned' beforehand.
29
30       NOTE: although optimisation plays a part in the pruning process, the
31       output project is exactly the same as the input except with 'bad'
32       points removed, you probably want to optimise the geometry of this
33       project with hugin or autooptimiser afterward.
34
35       This tool is heavily inspired by APClean, a similar tool for PTGui
36       project files by Fulvio Senore.  If you want a similar behaviour to
37       APClean without the optimisation steps, use the --fast option.
