Aruco Head Tracking Headphone Mount

thingiverse

This is a mount for headtracking using ArUco and Opentrack. More or less you generate an aruco tracker (link below), print it out 100mm wide with 10mm margins (the white parts you leave when cutting it out), glue it to this thing, strap the mount to your headphone band using a velcro cable tie (that's what I used, whatever works for you though), fire up opentrack, point your webcam at it, and you've got headtracking! I've also included an appropriately sized wedge to give one side of the tracker a 10mm elevation, as sometimes the software will have issues maintaining accurate tracking if your tracker is mounted directly perpendicular to the camera angle. Wiki for ArUco tracking, has info about why you might want to use the wedge: https://github.com/opentrack/opentrack/wiki/Aruco-tracker Link to the ArUco marker generator: https://chev.me/arucogen/ For more details on the setup process I'll leave you a link to a helpful video I found on the topic: https://youtu.be/w6CCzYy5hRs
