Tracking accuracy

Saphyr

Hello, im considering usage of the OAK camera and OpenCV AI for tracking real world object to synchronize his position and rotation to game object in Unity application. But i need to reach accuracy around 0.01 - 0.05mm in movement. Is it even possible? Thank you.

Hi Saphyr ,
No, 0.01mm is not even close to stereo camera accuracy. Please see depth accuracy specs here.
Thanks, Erik

Sorry comunication error with my colegue. The desired accuraci is 1-5cm. The real world object would be 8-10m far. There are two options. First the camera will be on the object facing to the wall with projection screen. Second, if its possible, there will be 4 cameras in every corner of the room and some IR LEDs on the object. The rear cameras would be significantly closer then the front ones, around 2-4m. But there is possibility, the LEDs will be sometimes covered for some one or more cameras by some obstacle. In principle, could it work?

Hi Saphyr
Still, the depth accuracy at 8-10 meters is pretty bad for normal OAK-D cameras (source).
Using something like charuco board with maximum resolution in the first option will probably give you better results. For IR LEDs you would have to use mono cameras, since the RGB uses an IR-cut filter.
But I am not sure whether you will be able to reach the desired accuracy.

Let me know how it goes.

Thanks,
Jaka
