g.gui.photo2image — Corrects scanning distortions of a paper photo. imagery, aerial, photo, GUI Name of input imagery group Name of input raster map The name of the camera (generated in i.ortho.camera) The rectification order (no of Fiducial=4 -> order=1, no of Fiducial=8 -> order=2) The name of the output files extension (used in i.rectify) This module is based on g.gui.gcp, the GCP manager of GRASS GIS. It is part of i.ortho.photo suite. The aim of this module is to give absolute location values to the fiducial points present (in number of 4 or 8) in a scanned aerial photo. This is necessary as (manual) scanning introduces distortions, rotations and also may not be limited to scan the boundary of the photo itself. It is thus necessary to give to each fiducial the exact coordinates in mm as given by the aerial photographic instrument design, which is unique per camera. This module requires you to have made a group with your aerial photo (i.group), a camera description file (i.ortho.target) and use them to launch the module. Additional requirements are the order of rectification (1 if no of Fiducials is 4, 2 if no of Fiducials is 8) and an extension file (if not given, defaults to \$filename_ip2i_out) An example for Location imagery60: Figure: Screenshot of g.gui.photo2image wxGUI See also video tutorials on GRASS Wiki. i.ortho.photo, i.group, i.ortho.camera, i.ortho.target, i.rectify, m.transform, v.rectify Markus Metz Based on the Georectifier (GRASS 6.4.0) by Michael Barton $Date$ Available at: wxGUI GCP Manager for photo to image registration source code (history) Main index | GUI index | Topics index | Keywords index | Graphical index | Full index © 2003-2019 GRASS Development Team, GRASS GIS 7.8.1 Reference ManualKeywords
