I’m flabbergasted how good this tracker-neuralnet plugin for #OpenTrack works. It does the #headTracking with just a webcam without any clips, reflectors or LED stripes. I kinda expected this to not work really well in a dark room, that I prefer for gaming, but I was wrong. Even with a tiny light in one corner of the room only it kept tracking flawless.

…can even scratch my nose and it keeps tracking.

To get this neuralnet tracker input in the first place I had to download the ONNX runtime package onnxruntime-linux-x64-1.18.1.tgz from https://github.com/microsoft/onnxruntime/releases/tag/v1.18.1 (My Fedora offered 1.15.1 from it’s repo but this was at the time of writing not sufficient and having it installed resulted in failure due to an API mismatch). I didn’t even install it somewhere, just unpacked it in my Downloads folder.

Back in my OpenTracks folder I run cmake the way I’ve done it before several times but this time I added the unpacked onnxruntime folder to the config.

Configure did it’s magic (note how it picked up module tracker-neuralnet once the ONNXRuntime_DIR was set) and here we are one make later. This is rather impressive 🤓

YMMV
