Timeline for open-vins documentation
-
Yeah those parameters are changed when you calibrate some sensors. @Viktor-Gal can you try calibrating the imu_apps on your drones via voxl-calibrate-imu and then retry flying OVINS and see if that helps?
-
@Zachary-Lowell-0 so those params are after running
voxl-configure-mpa; i still dont understand why there's a diff between the apparently same v2 starlings.i can run the imu_apps calibration and retry OV.

@Zachary-Lowell-0 hey so i did what you suggested, here's the full output of openvins server but it's the very same behaviour; the qvio is nicely picking up the movements, openvins is just stationary on the portal. here are the detailed logs:

@Zachary-Lowell-0 so those params are after running voxl-configure-mpa; i still dont understand why there's a diff between the apparently same v2 starlings.
i can run the imu_apps calibration and retry OV.
RE: No you are sending the PX4 parameters not the voxl2 parameters. Runnign voxl-configure-mpa will configure some px4 parameters, but after you open up qgc and then calibrateall the sensors in there, it will change some of those parameters, hence why those specific to imu calibration and mag cal are different from drone to drone. I highly recommend sticking to qvio with single camera tracking for now as OVINS is still heavily in development.

@Zachary-Lowell-0 i hear you, but could you maybe give some pointers how one could make the qvio more stable? as i said it is at the moment only has 25% success rate: meaning 1 out of 5 flights i dont have problems with the qvio, the rest of the time the drone becomes unstable and crashes.

@Viktor-Gal have you read through the troubleshooting VIO documentation? https://docs.modalai.com/flying-with-vio/#troubleshooting-vio
-
@Moderator yep, back and forth. unfortunately no change.
-
@Moderator et.al. i just want to follow up that switching to the nightly builds that uses out of box the openvins implementation for VIO, is significantly better than the qvio. in other words, it actually fixed all the problems that we were facing with the QVIO.
-
@Viktor-Gal Excellent, thanks for the feedback!
-
I'll put a question here since it's open-vins documentation related. I also am successfully running nightly builds of open-vins, and it is working well for me.
I would like to add image masks to the tracking cameras to block out certain areas. I see the option "use_mask" in voxl-open-vins-server.conf, which I can set to true. I can't figure out where to put the mask files, or how to specify their path and file name?
If this should be a separate thread, please let me know and I can move my question elsewhere, cheers!
