T265 for VR headset tracking
I need to track a VR headset. The optical tracking that comes with the headset can not be used because the headset is used inside a moving cabin.
Can I mount a T265 on the headset to track its position?
Note that we are inside a moving cabin. So if the T265 uses its IMU and combines this data with the camera information, it will not work correctly. Because the IMU will sense motion that the camera will not see. But maybe we can use only the camera part of the T265 and not the IMU?
It is a small cabin (about 1.5 meter diameter). Will that work? Do I need to add marks on the walls?
Hope somebody can comment on this.

In most (if not all) VR headsets, the optical tracking is combined with the accelaration sensor and gyroscoop information. This sensor fusion will fail if you use this system inside a moving cabin, because the optical system will measure movements relative to the cabin while the acceleration sensor and gyroscoop measure relative to earth.
In most headsets you can disable the optical part. Now we can add our own optical tracking, and an extra IMU on the cabin and do our own sensor fusing.
For this we need some (optical) tracking. I hope I can use the T256 for this. But if this T256 does internally some sensor fusion like the headset (combining the optical tracking with the acceleration sensor and gyroscoop infomation), then we can not use it.
So the question is if the T256 does this kind of sensor fusion and if so, if we can disable that and/or only read the optical tracking part (without sensor fusion).
