• Processing folder-input

A folder at "/data/footage" with the footage in subfolders. Normally a one subfolder per SSD will be created by the downloading script. The splitting script will search one directory down 

• Split All *.movs-button (If footage is recorded to the SSDs, internal or external)

Splits all *.mov files in /data/footage/FOOTAGE1/N/, where directory N contains *.movs, *.imgs or *.bins from the N-th SSD. The results are placed into /data/footage/FOOTAGE1/0 as if the footage was recorded onto PC.

• 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 /data/footage/FOOTAGE1) for the Eyesis Panorama Previewer.

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

• Copy All-button

Copies all the images into the specified directory for further processing in ImageJ. The source images can be selected for processing right at 
their own directory w/o copying.

• Eyesis4Pi 393 Panorama Previewer-link

Alternatively to Copy All allows to preview and copy selected panoramas for processing

• 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 (~3min/set)

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

Note: The output is an equirectangular projection of the whole panorama in jpeg format. Quick previews:

* Drag and drop to threejs demo

• Split images for WebGL Editor (<1min/set)

Cuts stitched panoramas into 8 pieces for the WebGL Editor.

Tiles for the WebGL Editor

• Compress images for Google Earth-button (~5sec/set)

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

• Generate KML for the WebGL Editor-button (quick)

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.
Note: "published" images should be accessible at this path (locally /<web_server_root>/panoramas/ = /<webgl-editor-path>/images/)

• 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.

• After images are split and KML is generated the results will be in the Processing root folder ready to be copied to the WebGL editor.

1. map.kml -> /<webgl_editor_path>/kml_files/
2. Splitted images -> /<webgl_editor_path>/images/
3. In the browser go to <webgl_editor_web_path>/pano_index.html
4. Don't forget to set up the database for the WebGL Editor - guide.
