Note: ImageJ is not included into the WebGUI at the moment because it's not yet modified for launching from a browser.

Footage procedures WebGUI

System requirements

• Linux OS (Kubuntu preferably).
• Apache2 web server.
• PHP
• ImageMagick - convert.
• Movie2dng
• Hugin tools - enblend.

Source

Available for direct downloading from the SourceForge.net or from a terminal window provided the GIT is installed:

git clone git://elphel.git.sourceforge.net/gitroot/elphel/footage_procedures

Installation

• Download the source files.
• Install the required software.
• Create a link from the web server root path to the source folder.

example: sudo ln -sf /<PATH_TO_FOOTAGE_PROCEDURES>/footage_procedures /<WEB_SERVER_ROOT_DIR>/footage_procedures

• It is assumed that the footage series are located at:

/data/footage/FOOTAGE1
/data/footage/FOOTAGE2
...

Step 1

Step 1

• Processing folder-input

A folder at "/data/footage" with the acquired images in the indexed subfolders.

• Filter Out Images with Non-Matching Timestamps-button

Filters out uncomplete panoramas (missing files).

• Generate KML-button

Creates a KML file (map_points.kml in the Processing folder) for Eyesis Panorama Previewer.

Note: /data/footage/FOOTAGE1 directory should have r/w rights for the map could be saved in there.

Step 2

Step 2

• N/A means only that it's not available in the WebGUI
• Please read an article about Post-Processing in ImageJ.

Step 3

Step 3

• Processing root folder-input

A root folder for post-processing - absolute path

• Sources subfolder-input

A folder with the JP4 source images in the Processing root folder - the sources are used for GPS data extraction.

• ImageJ-processed subfolder-input

A folder with the ImageJ plugin post-processing results to be stitched.

• Stitch-button

Launches "enblend" from a stitch.php script for all panoramas in ImageJ-processed subfolder:
 enblend -l 10 --no-optimize --fine-mask -a -v -w -o result.tif 1334546768_780764-*_EQR.tiff 1334546768_780764-*_EQR-*.tiff

• Split images for WebGL Editor

Cuts stitched panoramas into 8 pieces for the WebGL Editor.

Tiles for the WebGL Editor

• Compress images for Google Earth-button

Creates rescaled low resolution panoramas - so the KML file could be opened from Google Earth.

• Generate KML for the WebGL Editor-button

Scans all the source images in the Sources subfolder and creates a KML file with the GPS data. The file is saved into the Processing root folder

• Path prefix inside KML-input

Adds this prefix to the file name to make the final http link.

• Visibility-input

Tag inside the KML telling the Editor whether to show the panorama as a camera model ("1") or not ("0"). Use "1".

• Starting Index-input

KML records names.
