 It is highly recommended that you calibrate your images to reduce lens distortion. Doing so will increase the likelihood of finding quality matches between photos and reduce processing time. You can do this in Photoshop or `ImageMagick <http://www.imagemagick.org/Usage/lens/>`_. We also have some simple scripts to perform this task: https://github.com/OpenDroneMap/CameraCalibration . This suite of scripts will find camera matrix and distortion parameters with a set of checkerboard images, then use those parameters to remove distortion from photos.

 Docker Usage for undistorting images

 The ``undistort.py`` script depends on exiftool to copy exif metadata to the new images, so on Windows you may have to use Docker for the undistort step. Put the matrix.txt and distortion.txt in their own directory (eg. sample/config) and do the following:::
