Should I just buy the cheapest PS3 Eye camera from ebay and see whether I get the flat lens or round lens, and proceed accordingly?
Its a real hassle to determine if its a flat or round lens from the photos people upload on ebay, as they’re not very good quality.
Edit: I found a really cheap one on ebay which was at auction and got the highest bid (it was a little over 4 euro with another 4 shipping, so honestly not bad at all). When it arrives I’ll try out the steps in the video and report back here I guess. Hopefully it can help people when buying these cameras to not struggle looking for the rounded lenses and worry that if they dont get that one they cant do their project.
Really any webcam from the last decade gets the job done. The trick is to add a filter to ignore everything that is not on the IR wavelength. Configuring camera and OpenTrack correctly is also vital. Like most webcams get really really slow when the scene is dark trying to raise gain and exposure. This must be disabled or their fps plummet into oblivion.
Find my scribbles on https://beko.famkos.net/2021/07/08/diy-headtracker-for-gaming-on-linux-pc/ (or watch the video) - whole thing did cost me 5 EUR. Mebbe it has some pointers for you too.
