@Alex-Kushleyev said in M0173 with 4 AR0144 Tracking cameras:

@cbay , what happens with the third misp norm stream? Is it not available? Maybe you did not enable misp for that camera in voxl-camera-server.conf?

Before it was the exact same setup in voxl-camera-server, rebooted and it just works now so not sure what was happening

Another question.. did this work for you before or is this the first time trying to calibrate at half resolution? if you request the full resolution, do you get the non-zoomed image? i know it will be slow to display in voxl-portal, but you could still check.

If you enable EIS with default camera calibration (no intrinsics cal file). does EIS and zoom work as expected? note that your version of voxl-portal may not have the browser support for zooming, but the config file zoom should still work. If you want to use the latest voxl-portal for EIS, please use this branch : https://gitlab.com/voxl-public/voxl-sdk/services/voxl-portal/-/tree/eis-integration . however the initial zoom of the image coming from the camera server is not dependent on the version of voxl-portal.

@colombe-ai I'm not sure how much we're going to be able to help to get this going but I'd start with that magnetometer. Put an oscilloscope in the lines and see if you see any activity.

Hi @jon ,

OK got it. Actually, we already do have a passthrough mode that can accept raw data coming from linux (via voxl io server) and forward it to the UART connection for voxl2_io board, for reference, code is here : https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/voxl2_io/voxl2_io.cpp#L270

Let me figure out (remember) how to use it, I will update you soon.

@zauberflote1 We are using our own custom airframe. Our SDKs are 1.6.0 beta and 1.4.5. However, I also just spoke with a colleague who owns a Starling 2, and he confirmed our findings.

@Colby-Howell For further information, here is the configuration that we ordered.

Configuration SKU: MRB-D0012-4-V2-C29-M11-T9-K2
Configuration Description: “Kit: with Battery Pack and Controller” + “Dual 4k & Dual Tracking & ToF (C29)” + “Microhard pMDDL2450 WiFi and Ghost Atto 2.4 GHz”

We do not at the moment have the secondary Microhard modem for the master/slave connection.

Hi there, I would highly recommend upgrading to the latest SDK 1.6.2.

Q1: For voxl-vision-hub, openvins is just another [abstracted] VIO client, using the same MPA interface as QVIO. Thus, should work the same as QVIO.
Q2: There are no outstanding buffer conflicts between the 2 inputs in that SDK version. Though best to update to 1.6.2 as there have been numerous MPA improvements.

Q3: MAYBE ON GROUND, POSITION LOCK? is reporting that the barometer is reporting <1m and OVINS > 1m (-1 in NED space). It appears OVINS had a blow up, has recovered with a new origin in the local frame. Your output says it must have reseted in the ai/flying and hence the new local origin is above your landing point (fixed frame). Depending how you have PX4's EKF setup could lead to issues like the landing detector not working, or position error when running missions, hence why it's reported as a warning. Your output says it's at 0,0,-15 indicating OVINS restarted at ~15m up, but the PX4 baro says it's at 0. If outdoors, I recommend setting EKF2_HGT_REF = baro, if indoors, you'll need to reconcile a origin offset if VIO resets midair (qvio would require this as well) if using vio data directly waypoint manager (i.e. offboard waypoint mode or custom nav code)

Going forward if staying with 1.4.x,

edit /etc/modalai/voxl-open-vins-server.conf and change:
"en_vio_always_on": true, ssh into the drone and run voxl-vision-hub --debug_fixed_frame --debug_tag_cam --debug_odometry to compare values and see if there is a error in calculation possibly causing vision-hub to restart. move the drone around by hand, point it at a tag as needed and monitor the output from vision-hub. Should tell you where a possible conflict arises.

Hi @Tormod-Axelsson-Hagen
Our descriptions tell you all you might need to know to make your own power module:

2-6S tolerant (so VIN capable of up to ~25.2V+)

6A output at 5V

Current monitoring if you do not use our ESCs (our ESCs provide a current reading to keep PX4 and other autopilots happy and for accurate remaining battery %)

Connector format of your choosing but the Molex 4-pin MINI SPOX is the direct 1:1 for VOXL 2 https://www.digikey.com/en/products/detail/molex/0022057045/403343?s=N4IgTCBcDaIAxzGOBWA7HALCkBdAvkA

If you want to make this flexible for VOXL 2 Mini, make it capable of generating 3.8V and use the MOLEX MICRO ONE family of connectors https://www.digikey.com/en/products/detail/molex/2059720041/13235081?s=N4IgTCBcDa4AwFYCcB2Mc4BYCMIC6AvkA)

The rest is up to you based on your design intent and supply chain constraints and preferred vendors.
Hope this helped!
