Usage

Usage

The general usage of listomvg is

 listomvg [options]

where the options are

 -i  string  image directory (mandatory)
 -o  string  output directory (mandatory)
 -m  string  mac address (mandatory)
 -d  string  mount point (mandatory) 
 -f  value   (optional) If you want to set a constant focal value for all images
 -p  1/0     (optional) Use (or not) principal point of calibration. Default is 1 
 -r  1/0     (optional) Compute lists.txt for global method with rigid rig. Default is 1
 -a  timestamp  (optional) Lower bound of timestamp to be used in 3D reconstruction.
 -b  timestamp  (optional) Upper bound of timestamp to be used in 3D reconstruction.

Examples

We suppose here that we are in an openMVG folder with contains only an image folder

  openMVG/
      images/
      channel.txt

and we want to create the file lists.txt, located at openMVG/matches which is related to the images that are in openMVG/images/folder. We also suppose that camera folder is mounted in directory /data/. Then, supposing that we are in the openMVG folder, the commands to generate files are the following

For lists.txt file using rig structure, principal point and focal of calibration,

 listomvg -i images/ -o matches/ -m AA-BB-CC-DD-EE-FF -d /data/

For lists.txt file with timestamp range and rig structure,

 listomvg -i images/ -o matches/ -m AA-BB-CC-DD-EE-FF -d /data/ -a 012345679_012345 -b 1234567890_012345

For lists.txt file with constant focal and principal point at the center of image,

 listomvg -i images/ -o matches/ -m AA-BB-CC-DD-EE-FF -d /data/ -f 2050 -p 0

For lists.txt file using principal point, focal of calibration and no rig structure,

  listomvg -i images/ -o matches/ -m AA-BB-CC-DD-EE-FF -d /data/ -r 0
