NAME ^

ptoclean - prune improbable control points

SYNOPSIS ^

ptoclean [options] --output better.pto notgood.pto

 Options:
  -o | --output     Filename of pruned project (can be the the same as the input)
  -n | --amount     Distance factor for pruning (default=2)
  -f | --fast       Don't run the optimiser for each image pair (similar to APClean)
  -v | --verbose    Report some statistics
  -h | --help       Outputs help documentation

DESCRIPTION ^

ptoclean takes a hugin .pto project and removes inconsistent control-points. 'Bad' points are determined by calculating the average error distance and standard deviation (Sigma), then removing any points with an error distance greater than the average by n * sigma. This pruning is performed on each pair of images in turn and then finally on the project as a whole.

Additionally the autooptimiser tool is run on each pair of images separately before each calculation, so there is no need for the project to be 'nearly aligned' beforehand.

NOTE: although optimisation plays a part in the pruning process, the output project is exactly the same as the input except with 'bad' points removed, you probably want to optimise the geometry of this project with hugin or autooptimiser afterward.

This tool is heavily inspired by APClean, a similar tool for PTGui project files by Fulvio Senore. If you want a similar behaviour to APClean without the optimisation steps, use the --fast option.
