Focal length will even change if the lens is focused to a different distance, cheap and simple lenses like in webcams certainly do so. I think this is a waste of time and effort, chasing after FOV and focal length, when considering every lens will have a different projection formula. The vertical FOV is 45° (again 1.6 ratio). But it does have slight distortion, making the image look a little bit like a 3mm fisheye. At 75° as a true rectilinear lens it seems to have a 3.2mm focal length. But it does have a slight barrel distortion, making it somewhere between a true rectilinear lens and a fisheye. This seems correct when assuming the lens is rectilinear (we can see it really doesn't distort much at all) and measurements using photos.

The PS3 lens seems to have it's FOV specified in diagonal, after all. Feels natural.ģ6.74845 is close enough to my "optimal" found value (~35) and doesn't show much difference in output.

This leaves a slight "floating" movement of a couple pixels when I don't move (but in fact I do, we all breathe and don't keep our head perfectly still), very slow and subtle. Translation sensitivity 0.5mm (filters out all translation "noise") Also, at 75FPS, the camera itself gives a rather noisy image, even at minimal gain, with lots of vertical stripes.Ĭamera at Using yaw and pitch mapping set to 90 input and 180 output. My PS3 cam still has it's IR filter, so I must use slightly higher gain settings, making the image slightly noisy. I hope this number is useful.Īnd yes, after moving in Z, yaw response was still minimal.Īs for accela settings, I can't use it without any filtering. Instead of detailing results here's the conclusion: In all three cases the optimal FOV value was about 1.6 times smaller than the real camera FOV. Tested two cameras, an old TEAC MX-6 with an unknown lens, measured 24° FOV (probably not the original lens) and the PS3 Eye. Optimal final yaw response was considered within +-5 in game data. Tested with a good office chair instead of a wobbly moving human! Nicely kept parallel to the sensor plane, so the only motion was in the X axis. Move in X to the edge of the frame, then adjust FOV until yaw reaction comes close to zero. Where to begin solving this problem?įinding the optimal FOV setting turned out to be very easy. Using the camera offset settings, the issue can only be resolved for one direction, and using the center command will make it as if I never set any camera offset values at all. So the camera looks straight ahead and slightly downwards to see the LEDs exactly in the center of the frame.

My camera is located on top of my screen on the right side, about 15cm above the center LED in the clip and directly in front of the clip, as it is mounted on my right side of the headset. Sure I checked the output remap, it's all fine there. If I move left, the view will move left correctly, but also will yaw to the right, giving the feeling as if I'm moving normal to a sphere. For example in a game, the view yaws to look roughly at the original center point. When translating in the X direction, the tracker responds with very much yaw and apparently correct translation. So far I have only found a single issue with my setup. Thanks a lot for all this work, a perfect alternative to the old FreeTrack and obvious answer to commercial trackers that cost a fortune. Overall the accuracy in RC13P2 is awesome and response time feels very natural and comfortable, with PS3 eye at The new threshold setting doesn't seem to make much difference than before, all is still very good.
