Is there a board available that is similar to the VOXL 2 Mini Dual High-res and Boson MIPI Adapter (MCCA-M0194-1) for tracking cameras?
We are looking to connect 2 M0166 cameras to a VOXL 2 Mini as a synced stereo pair without using the M0173 board. Thanks!
Hi! I'm trying to set up DFS using ar0144 cameras. I have the voxl-camera-server side working, and I'm able to view the stereo preview stream on voxl-portal. I've set up my extrinsics and intrinsics using voxl-calibrate-cameras and have acceptable reprojection error.
However, when I run voxl-dfs-server I get these errors:
ERROR computing undistort on left image in mcv_cvp_undistort_and_dfs_process
ERROR performing undistort+DFS pipeline
ERROR computing UD+DFS pipeline on CVP
Whether I enable or disable cvp rectification in the .conf file, I am facing errors. Let me know how I might be able to resolve this, thanks!
@Eric-Katzfey Thanks for helping me out with this! I've made some progress at narrowing in on the problem. First to answer your questions:
voxl-qvio-server disabled, this didn't change anything.voxl-open-vins-server. Now the ovins translation and rotation outputs look healthy, and time_usec increments normally, but the external autopilot still does not log the odometry output.I was able to get qvio odometry outputs to log on the external autopilot, but when I switched over to ovins, it fails. With ovins I still see incoming VIO (comp IP 197) heartbeat and timestamp mavlink messages going through, but not the 331 odometry message.
Let me know what you think, thanks so much!
Here's the output of voxl-version:

@tom I have some updates, and here's more info on my setup!
voxl-open-vins-server is running and outputting the following:
voxl-vision-hub and voxl-mavlink-server are running, and the odom messages are being sent. Here's the output from voxl-mavlink-server -l:
At my external autopilot, the Odometry messages are coming through, but the values are not populating/reading correctly:
Thanks in advance for any input you may have!
@Alex-Kushleyev We have been advised that the ov sensor modules for dfs are approaching end of life. Which camera options do you recommend we consider instead? Thank you for your help!
@tom Thanks! I referred to this page in order to set up what I have right now.
My voxl 2 mini is connected to the external autopilot using the one exposed UART. It seems to be connected fine, since I'm receiving the voxl heartbeat on the autopilot end, and I'm receiving autopilot mavlink messages on the voxl side.
I wonder if there is anything I might be missing on the voxl-vision-hub side, or elsewhere.
Thanks for your help!
Hi! I'm trying to use voxl-vision-hub to send voxl-open-vins position data to an external autopilot (ardupilot). I start by making sure the following services are running:
I can confirm that the voxl and external autopilot are connected because I see this on Mission Planner MAVLink Inspector:
and the debug output I see after running voxl-vision-hub -d is:
voxl2-mini:~$ voxl-vision-hub -d

It seems like other than the heartbeat, no data is being sent to the external autopilot. Thanks in advance for any guidance that can help me sort this out!
Looks like modalcv feature tracking is only set up for the ar0144 camera and not the ov7251 camera. Could you please extend feature tracking capability to other cameras? Is there any way I can do this on my end?

I've upgraded to the latest SDK. I'm not using an aircraft, I'm working with the voxl 2 board only, with a tracking fisheye ov7251 camera. The intrinsics and extrinsics are set up correctly, I was able to confirm this because qvio works well.
I've traced back the error message
ERROR: Width/Height mismatch, optic flow w/h should be [640 400] , instead got [320 240]
to voxl-feature-tracker/src/main.cpp line 650:
cvp_tracker_vec[ch].init(ch, width, height);
This leads back to mcv_cvp_feature_tracker_init from libmodal_cv which is closed source.
How can I run the ovins internal-mode tracker? Let me know if you have any further ideas to help me get ovins working Thanks!
