Hi all, our Depthkit console no longer displays sensor streams when loading, previewing, calibrating, or streaming. Previously we were able to see the various sensor views but now that portion of the console is grey. Any suggestions on how to resolve this?
I read through a previous post with a similar issue - Empty Multi Cam Display in DepthKit 0.6.2 - #10 by CornellTech - but I don’t believe any of the same circumstances apply to our problem. The entire system was working fine for a number of months and, as far as we are aware, nothing has changed with the hardware or software.
@DesignInnovationKSU - A couple of suggestions to help narrow this down:
- I see from the serial numbers in your screenshot that you’re using Orbbec Femto Bolt sensors. Have you restarted the sensors recently? See this note: Periodically power cycle Orbbec Femto Bolt sensors
- Can you share the contents of the Depthkit console log?

We cycled the power on all of the Femto Bolts and restarted the system, but didn’t notice any change.

Apologies, it looks like our first power reset did not include removing the USB cables from the Femto Bolts. Once we unplugged all connections and restart the system the issue appears resolved. Thanks for your help!
Thanks for following up. It’s good to hear that restarting the sensors resolved the issue.
Our team is investigating ways of automatically detecting when the sensors go into this state which produces erroneous timestamps to consider for future versions. We’ll post any updates here.
