OAK-D Pro PoE Depth Not Working

jlclemon

SOLVED IN 2.17.3

I just got my OAK-D Pro PoE and I am having issues getting stereo depth working. When I run the python3 depthai_demo.py I can only see the left stream and the color stream. I cannot see the left rectified, right, right rectified or the depth. When I choose those the image remains on the last good image I got from the other stream. Then when I try to run the depth_preview.py example this happens:

python depth_preview.py
Traceback (most recent call last):
File "C:\Users\jlclemon\Documents\workspace\depthai\depthai-python\examples\StereoDepth\depth_preview.py", line 51, in <module>
inDisparity = q.get() # blocking call, will wait until a new data has arrived
RuntimeError: Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'disparity' (X_LINK_ERROR)'

My host is running windows 11. The device manager is showing:

Bootloader version: 0.0.19
Depthai version: 2.17.1
Device State: BOOTLOADER

Any help on this would be greatly appreciated.

Hello jlclemon ,
We apologize for the issue. Could you please copy the full terminal log when you start the depthai_demo.py? I'm wondering what could be the reason for the right camera to not work as expected. Could you also try running the mono preview example?
Thanks, Erik

Here is the output with the depthai demo:

And as for running the mono camera preview, only the left camera stream opens. The right stream does not pop up and there is not output about why. I can verify that with my oak D lite I get both streams with this demo.

For helping troubleshoot I am attaching an example color image and the left image I get from the demo script.

After I closed the window on the demo I notices the fps was added to the output so I pasting the output again with that last bit added:

Hello jlclemon ,
Could you please provide the full output of this script? Maybe via pastebin.com or similar website.
And could you also try updating depthai to latest version? You can update it with python -mpip install depthai -U, and then skip version check (python depthai_demo.py --skipVersionCheck [other arguments]).
Thanks, Erik

erik I have not run the script yet but I can confirm that upgrading to 2.17.3 seems to have gotten me a stream from the right camera and I am getting a depth image. If you still want the calibration information I will run the script tomorrow.

jlclemon

jlclemon Decided to get the calibration script out of the way.

You can mark this as solved by using 2.17.3.

jlclemon Thanks for circling back and confirming it works!
