i have a question about tracking with realsense t265 [SOLVED]

FAQ Camera Tracking

 

im using realsense t265 as a tracker


i have setted everything up and when i rotate the camera

background (unreal) moves and camera moves but it doesn't track keyed object... 

even if i turned the manual lens on.

[ SOLVED ] 


i was because of my poor calibration. i tried to calibrate better and the result got better.

Hi Mantri,

Using T265 shouldn't make your calibration process any different from using other tracking devices.

Which Aximmetry calibration solution do you use, the Camera Calibrator or the Basic Calibrator?
Also, do you use REtracker with the T265?

If you are using the Camera Calibrator.
Please read this page: https://aximmetry.com/learn/tutorials/for-studio-operators/camera-calibrator/
And after that, you should be able to use the Camera Calibrator. But if you want to see an example of it, you can check out this video: https://www.youtube.com/watch?v=uCXTZ5PGOLE 

If you are using the Basic Calibrator.
Please read this: https://aximmetry.com/learn/tutorials/for-studio-operators/basic-lens-calibration-without-lens-distortion/
Also, we have a video version of this documentation: https://aximmetry.com/learn/tutorials/for-studio-operators/basic-lens-calibration-video-tutorial/

Warmest regards,

Hi,

Is it possible to use the camera calibrator with Retracker  and T265 ?

Given how it works, I thought it was only compatible with the "native" tracking systems of Aximmetry (eg : vive trackers, antilatency and professional systems...)

Eifert@Aximmetry thanks for your respons .

i am use sony Z190 and tracking device T265,

should i have retrakcer software again ? 

i was buy calibration from aximmetry.

and one think, z90 there is no list in calibration software aximmetry

Hi Eric,

It is possible to use the camera calibrator with T265.

You don't need Retracker, I was asking it to know better how are their setup. The Intel Realsense is considered an Experimental tracking system in Aximmetry. Please note that Aximmetry does not officially support using experimental camera tracking systems. We strive to create the means for your experiments in Aximmetry, but we cannot provide any support for these and we cannot guarantee any result. https://aximmetry.com/learn/faq/hardware/#which-aximmetry-edition-do-i-need-to-be-able-to-use-a-professional-camera-tracking-system
Intel Realsense has been added in version 2021.2.0: https://aximmetry.com/learn/unlisted/for-users/software-version-history-older/#%E2%96%BA-2021-2-0

You can calibrate almost anything with Aximmetry as long as Aximmetry supports that tracking hardware or tracking protocol.

Warmest regards,

Hi Sumantri,

You don't necessarily need Retracker to use T265 with Aximmetry.

Indeed PXW-Z190 or PXW-Z90 is not on our list of Sensor widths. However, you can still search for their sensor sizes or ask the manufacturer/seller for them. And then give the size as Custom in the Calibrator:

Warmest regards,

Hi,

After connecting the Intel Realsense to your computer, you should see it in the Aximmetry Calibrator like this:

In Aximmetry Composer, you could for example use the Edit->Device Mapper to map it to a camera tracking slot:

Thanks 

      Can we use Intel realsense  D430 ?

Hi Kamran,

D430 is not supported.
Note that D435 doesn't provide tracking data of itself, so it would be very hard to use for camera tracking.
While T265 calculates and makes its location and rotation available.

Warmest regards,

Dear Eiffert,


I successfully calibrated my lens . 1 question.. My Camera is GH-5 and it is listed there as Sensor. I additionally use a Speedbosster adapter attached and does 0.7 multiply. SO do I need to calculate this when inputting my sensor size.? As the Booster changes my Lenses Focal Distance.? Exactly so: My 24-70 Lens becomes after the Booster to 35-100 Has it got anything to do with my sensor size input.?

Hi,

Adapters won't change the sensor size. In the Calibrator, keep the GH-5 Sensor width as it is:

However, note that after switching adaptors or lenses or anything that slightly changes your lens parameters, you need to make a new calibration.

Warmest regards,
