Description

PlenoptiSign is an open-source app for geometry estimation of a light field captured by a Standard Plenoptic Camera (SPC). This software treats a pair of light field rays as a system of linear functions whose solution yields ray intersections indicating distances to refocused object planes or virtual camera positions of perspective views (so-called sub-aperture images).

Command-line interface

  • Installation:

    For ease of use, you can install with pip:

    • $ pip install plenoptisign

    Alternatively, installation is possible from source via:

    1. download the source using $ git clone https://github.com/hahnec/plenoptisign.git
    2. go to the root directory $ cd plenoptisign
    3. install with $ python setup.py install from the root directory
  • Usage:

    Run $ plenoptisign from the command line with optional arguments:

    • -g, --gui: open graphical user interface
    • -p, --plot: plot paraxial rays
    • -r, --refo: refocusing results only
    • -t, --tria: triangulation results only
    • -h, --help: print help message

    Unit testing is done with $ python plenoptisign/tests/plenoptisign_unittest.py -v

CGI server

  • Installation:
    1. download the source

    2. place extracted plenoptisign-master folder on the ftp next to your *.html that you want to embed it in

    3. rename plenoptisign-master to plenoptisign

    4. include cgi.html into your *.html with includeCGI as the id of the desired div container

      <script>
          $(function(){
              $("#includeCGI").load("plenoptisign/plenoptisign/bin/cgi.html");
          });
      </script>
      .
      .
      .
      <div id="includeCGI"></div>
    5. give sufficient permission (chmod 750) to the file plenoptisign/plenoptisign/bin/cgi_script.py

  • Usage:

    website demo: http://www.plenoptic.info/pages/software.html

Tested on macOS 10.14.2 and Windows 10 w/ Python 2.7 & Python 3.6
