M0173 dual tracking camera error

[Jetson Nano]

@Alex-Kushleyev can you please share the calibration file opencv_tracking_open_intrinsics.yml and opencv_tracking_down_intrinsics.yml.

@Jetson-Nano Is this a Starling 2 drone that you're using? If so, if you provide the serial number of the drone I can provide the calibration files. If not, you'll have to do the calibration yourself using a calibration card.

[Jetson Nano]

@tom Yes I am using the starling 2 drone. I changed the camera modules to the latest cameras with M0173 board.
where will I find the serial number?

[tom]

@Jetson-Nano The serial number is likely located somewhere on the frame of the drone. Should be on a white sticker and have the form MXX00000XXX

@Jetson-Nano oh sorry I missed that you swapped to the M0173 + AR0144s, in that case you will have to recalibrate the cameras yourself as all I have is the original camera calibration which won't match your new setup

@tom @Alex-Kushleyev @Eric-Katzfey
I calibrated the camera, now i am not getting error while running the qvio-server, but different debug message

Still I am not able to get data from voxl-mapper. how can I use the vio data from open-vins-server rather qvio-server

@Jetson-Nano , can you please clarify what you are working on? Are you setting single camera QVIO or your custom drone or dual camera Open Vins? Is it a custom drone and have you created correct extrinsic calibration files for the cameras / IMU transforms?

@Alex-Kushleyev, I using voxl2 with M0173 board with camera config 29.
The errors are now solved, I made the necessary changes and reconfigured every server and pipeline and calibrated the cameras.
