Preface

The following page describes the Eyesis camera post-processing procedures.

Eyesis Output

Fig.1 Eyesis frames
  • 3x HDDs, each containing *.mov files from 3x 3-sensor modules (a single HDD is connected to an individual camera module).
  • Each frame in a *.mov file is a combination of frames from 3 sensors glued vertically - triplet.
  • The modules are numbered - 1,2,3 - having individual ip address:
192.168.0.221 
192.168.0.222
192.168.0.223
  • The sub images are [1.1, 1.2, 1.3], [2.1, 2.2, 2.3], [3.1, 3.2, 3.3]. 3.1 is the fisheye image.
  • The frames in *.movs are indexed.
  • A single image format is JP4 (a raw format with a higher quality and frame rate against *.jpeg).
  • Corresponding frames have the same time stamps generated by the 1st camera.
  • The 1st camera frames are geotagged.

Post-Processing Setup

  • HDDs are put into a processing PC and the data is copied.

Workflow

GUI (Eyesis operating, installed on the laptop used for controlling the camera)

Elphel Eyesis SDK software (pre-installed), for post-processing:

  • Movie2DNG - extracting JP4 (JP4 is the Elphel raw image format) images from *.MOVs.
  • ImageJ (by 3rd party) - ImageJ with Elphel plugins (image quality enhancement, color balance) for processing JP4s to create TIFF/JPEG output;
  • Hugin tools (by 3rd party), with Elphel PHP scripts for automatic work is used for panorama stitching;
  • ImageMagick # (by 3rd party), also with a PHP scrip by Elphel is used for converting/modifying panorama JPEGs - scaling for WebGL panorama viewer;
  1. other pre-installed PHP scripts:
    • exif2kml.php - extract the GPS data from images and put it all to a KML file of the route.
    • create_links_xml_file.php - read the KML file and create file with records-links of the route points. It is used in Elphel WebGL Viewer

other:

  • Ufraw (by 3rd party) - to view/process DNG/TIFF
  • Dcraw (by 3rd party) - for converting JPEGs

Processing panorama possible steps

  • A stitching template *.pto should be created in Hugin (created once and reused later). Elphel is providing a sample template with the camera (individual for each).
  • Copy all the *.mov files to certain locations (folders must have the r/w rights enabled for everyone):
Currently:
hdd1: /data/disk/<footage_name>/
hdd2: /data/disk-1/<footage_name>/
hdd3: /data/disk-2/<footage_name>/
  • http://127.0.0.1/scripts/split_mov.php?dir=<footage_name> - (usage TBA) - it applies Movie2DNG to all the footage files. The output is JP4 files.
  • http://127.0.0.1/scripts/exif2kml.php?dir=<footage_name> - it extracts the GPS data from images and put it all to a KML file of the route. The output is a KML file.
  • Launch ImageJ and process the files. The output is JPEGs (optionally, TIFF). (This step can be skipped, but some other converting to JPEGs is required then - movie2dng+dcraw, for an instance).
  • http://127.0.0.1/scripts/stitch.php?dir=<dir_name> - stitches the images processed ImageJ using Hugin tools.
  • http://127.0.0.1/scripts/convert_images_for_webgl.php?dir=<results_dir> - rescale results using ImageMagick.
