Should I send back my camera to change it ?

Antoine

Hello,

After some weeks of struggling with our Luxonis OAK-D-Pro-W, I am asking myself if I should ship back our camera to the support to exchange it. I don't understand along all the problems if it is related to the device or not.
To summurise all my current problems on this camera :

Problems with Depthai-python code examples :

ERROR: cannot launch node of type [depthai_examples/stereo_inertial_node]: Cannot locate node of type [stereo_inertial_node] in package [depthai_examples]. Make sure file exists in package path and permission is set to executable (chmod +x)

When launching any scripts I now have the following issue :

script_edge_detector_saving_frame.py:37: DeprecationWarning: RGB is deprecated, use CAM_A or address camera by name instead.
  camRgb.setBoardSocket(dai.CameraBoardSocket.RGB)
script_edge_detector_saving_frame.py:41: DeprecationWarning: 
LEFT is deprecated, use CAM_B or address camera by name  instead.
  monoLeft.setBoardSocket(dai.CameraBoardSocket.LEFT)
script_edge_detector_saving_frame.py:43: DeprecationWarning: RIGHT is deprecated, use CAM_C or address camera by name  instead.
  monoRight.setBoardSocket(dai.CameraBoardSocket.RIGHT)

When launching an example using the IR dot projector,I have the following error : [error] No IR drivers were detected!

Problems with dai_ws ROS examples :

When I try to use dai_ws depthai-examples; I always have this issue :
ERROR: cannot launch node of type [depthai_examples/stereo_inertial_node]: Cannot locate node of type [stereo_inertial_node] in package [depthai_examples]. Make sure file exists in package path and permission is set to executable (chmod +x)
When trying to launch stereo_inertial_publisherexample, rviz is launching but I have these warnings :

I am having so much issues with the same camera that I started to chat with the support to exchange it and ship it back. I am still trying to test things to use it and not giving up on this camera.
Today I wanted to ask the support if all these errors could be related to the device and if I should ship the camera back. I would be a big time los for our project but we can not continue with this camera if it is not working.
Should I ship it back ?

Thank you very much for your respond.
Antoine.

Hi Antoine ,
Could you try running the depthai_demo, and cam_test.py, and paste the results here?
Regarding ROS, I am not sure what the issue could be. Regarding warnings, you can ignore them, but we will be fixing that soon. Regarding IR drivers, it would be helpful to get results of above scripts. Could you also share your order number?
Thanks, Erik

Antoine

Hello Erik,

As you suggested, I tried the depthai_demo script and here are the results from it :
When I launch it, here is the result in the terminal :

Using depthai module from:  /home/antoine/.local/lib/python3.8/site-packages/depthai.cpython-38-x86_64-linux-gnu.so
Depthai version installed:  2.21.2.0
Setting up demo...
Available devices:
[0] 184430100103AA0F00 [X_LINK_UNBOOTED]
USB Connection speed: UsbSpeed.SUPER

The window is opening like so :

Nothing is changing, the "Starting Demo" stays like so.
I tried some of the different output avialable with the "color" button on the top left, but nothing change and the "starting demo" text stays here.
For example, when changing from "color" to "left" and cliking "Reload" and "Apply and "Restart" :

Stopping demo...
=== TOTAL FPS ===
[right]: 0.0
Setting up demo...
Available devices:
[0] 184430100103AA0F00 [X_LINK_UNBOOTED]
USB Connection speed: UsbSpeed.SUPER

and the image result :

The only one changing something is the "right" one :

It's like if the only camera still "plugged" is the right one, but without really working. Note that the camera did not fall of get any damages and I had some results with it during the last mouth.
For example, I tried to use the edge detector :

Here another example of me trying one of the edge_detector scritpts in /depthai_python/examples/Scripts :

But then we've got the problems with the IR sensors and now nothing is responding at all.

About the IR sensors problems,
I also used thescript_multi_roi_spatial_calculation.py script, and had some results.
This picture is a script I've created by merging the multi_roi_spatial_calculation_scrip with a modified edge_detector script :

When I launch the script_multi_roi_spatial_calculation.py :

~/depthai-python/examples/Script$ python3 script_multi_roi_spatial_calculation.py 
[184430100103AA0F00] [3.2.1] [1.205] [system] [error] No IR drivers were detected!

All of these programms where working and then not anymore. I am struggling to understand why I can't use the camera properly anymore.

I hope all of these informations are usefull for you and that we would be able so solve all these problems, maybe by changing the camera.

Best regards,
Antoine.

Hi Antoine ,

I believe that's the case, and you can test that by running cam_test.py and checking the output. Could you copy the output of cam_test, please?

Antoine

Shure, here is the result from cam_test.py :

~/depthai-python/utilities$ python3 cam_test.py

Antoine what about cam_test.py -rs (to avoid gui / pyqt dependency)?

The right camera is working, event if the output image is very bright (I can see my finger when it is very close to the camera).
For the 3 others output: rgb, left and camd, as you can see the windows appears black.

Here is the output from the terminal :

~/depthai-python/utilities$ python3 cam_test.py -rs

Hi Antoine ,
Thank you, this confirms the hardware errata - we have had a few such cases where glue gets in between the camera connectors, which unables them to stream video. Please send an email to support@luxonis.com (with this url) and we will replace it asap. We apologize for the inconvenience.

Antoine

Thank you very much for your response.
Best regards,
Antoine.
