Hi everyone,

we managed to get OpenVINS running on our setup (similar to a Starling C27). In the VOXL Portal, under the VIO tab, the trajectories and motion estimates look good so far, so OpenVINS itself seems to be working correctly.

However, we can’t find the ov_overlay in the Camera tab to visualize the tracked features from the tracking cameras. According to the documentation
(https://docs.modalai.com/voxl-open-vins-server), there should be an ov_overlay available in the camera view, but it doesn’t appear for us.

Has anyone encountered this issue before or knows what might be missing or misconfigured on our side?

Thanks a lot for your help!

@Dronodev 
ov_overlay is now available under the VIO tab in voxl-portal. Please make sure to update your system to the latest released SDK.

@zauberflote1 I updated my system to the latest SDK 1.6.2 but unfortunately when I am in the VIO tab in voxl-portal, nothing happens when I click on the little tv-icon. Is there anything I need to configure to display the camera overlay?

@Dronodev 

Can you confirm you have the raw feed button? Please give a try if you have.

Example follows:

@zauberflote1 

Unfortunately i don't have the raw feed button. This is what my vio tab looks like:

When I try clicking on the little tv-icon at the top, nothing happens.

To be sure I configured everything correctly here is my config:

system-image: 1.8.06-M0054-14.1a-perf
kernel: #1 SMP PREEMPT Wed Oct 22 04:13:18 UTC 2025 4.19.125
mach.var: 1.0.1
SKU: MRB-D0014-4-V1-C27-T0-M28-X0
voxl-suite: 1.6.2

Is 1.6.2 the newest SDK ?
I donwloaded the SDK from here: https://developer.modalai.com/asset/eula-download/188

It will be released on 1.6.3. If you need the feature now, you can always build it from source and deploy to your voxl.
