I’ve long been interested in 360 panoramic photos and videos and being a patient tech consumer, I was fortunate to get the 2016 Gear 360 camera for the low price of £80 shipped; 22% of the original launch price of £350.
Additionally, I wrote a simple 360 web viewer, so I can use any image host (e.g. Imgur, Dropbox, etc.) and not be tied to a specific online platform like Kuula.
You will have to install Hugin manually rather than via
brew cask install hugin as the cask formula usually is out of date with the official releases. Go here to find the latest binaries: https://sourceforge.net/projects/hugin/files/latest/download
Once installed, clone this project https://github.com/ultramango/gear360pano. Now you can use the HuginStitchProject tool installed as part of the Hugin package to use the template files
gear360sm-c200.pto (if using the Gear 360 SM-C200 camera) to stitch your dual fish eye photos together to form a spherical 360 photo.
Note: You can either edit the PTO file and change references to “dummy.jpg” to “your_input_filename.jpg” or simply rename your input file to “dummy.jpg”.
You can use
exiftool to add metadata so Facebook (and possibly more social media in the future) can recognize the image and use the appropriate viewer on the platform.
# Install exiftool brew install exiftool exiftool -ProjectionType="equirectangular" photo.jpg # 'photo.jpg' is the photo you want to tag
Haven’t figure out a way to get multiblend to compile on OSX so we’ll have to use an alternative projection tool.
We can use this tool to roughly convert a 360 video https://github.com/raboof/dualfisheye2equirectangular
Follow the instructions to compile
gcc -o projection projection.c -lm and then ensure that the command to generate the mapping file is taking the correct dimensions of the video input.
e.g. If the MP4 files are in total 2560x1280 then the command would be
./projection -x xmap_dokicam_video.pgm -y ymap_dokicam_video.pgm -h 1280 -w 2560 -r 1280 -c 2560 -b 35 -m samsung_gear_360 vs the example given in the project instructions
Use ffmpeg (install via
brew install ffmpeg) to convert your video file:
ffmpeg -i movie.mp4 -i xmap_dokicam_video.pgm -i ymap_dokicam_video.pgm -filter_complex remap out.mp4
If uploading to YouTube, use Google’s SpatialMedia metadata injector tool to allow YT to identify the upload as a spherical (equirectangular) 360 video. https://github.com/google/spatial-media/releases
The Gear 360 uses the Accessory Devices Bluetooth protocol to talk to paired phones
