I just bought a new OAK-D W camera to evaluate for our robots. I have only gotten the camera to work once, very briefly, with the demo app. I have used an OAK-D Pro successfully, but am having a lot of problems with this new camera.

Camera P/N: OACK-D-W-97
OAK-D Wide OV9782
System: Ubuntu 22.04.2 LTS, Linux 5.19.0-50-generic

I have tried using the depthai_demo.py app, the ros1 launch file examples and the ros2 launch file examples. They generally report the same error:

[1944301071E4722700] [1.1.1.1] [1.718] [ColorCamera(0)] [error] Camera not detected on socket: 0

Subsequent runs of the depthai_demo.py sometimes produce different errors:

After pulling this latest branch, I re-ran python requirements install (python3 install_requirements.py).

The time that I did get it to work was the first reboot after installing all of the dependencies for the first time. When I tried to change the "SHAVEs" parameter, everything froze, then crashed. After that, I couldn't get reconnected to the camera, even after a reboot.

What do I need to do to fix this? Is this a hardware problem?

    jakaskerl There is no script in the depthai repo called cam_test.py. The only script that is close to that is tests/guided_manual_test.py, which just repeatedly starts the depthai_demo.py script in various modes, but it gets exactly the same errors that I posted above and then reports "Success!" at the end (even though nothing was successful).

        Thank you for the reply.

        Unfortunately, I think this error is completely unrelated to the OAK-D W camera. I tried running this with my OAK-D Pro and got the same crash.

          travis_riggs Instead of running python3 cam_test.py, could you try running python3 cam_test.py -rs, which should skip the qt requirement (no GUI), and just use opencv?

            That is a much better proposal.

            Here is the output:

            Note that this is running 2.21.2.0, which is the version that depthai_demo.py wants. Earlier, I was trying to run with 2.22.0. Does 2.21.2 support the OAK-D W?

            I am hesitant to go through some of those uninstall/reinstall steps because, at the moment, I at least have something working for the OAK-D Pro. I can run depthai_demo.py and the ros2 examples to evaluate my OAK-D Pro camera. Before, while going through some of the troubleshooting steps of messing with my dependencies to get the Wide camera to work, it broke my ability to run the OAK-D Pro.

              Hello here from Japan. We bought two cameras from a retailer and we seem to have the same kind of issue. Only mono cameras are working on the oak-D PRO WIDE.
              Camera worked on the initial pipeline we tried and since then we have nothing. One thing is that we were using the camera in multi-threading and the issue might be related to a non-clean exit ? However if it is software related, I would supposed it would have been fixed by unplugging the camera

              We tried using the device_manager to reset our devices but it seems to only reset the calibration.
              Running the cam_test here are our logs

              To test I built the C++ version of the code from the develop branch but did not have more success.

              We also tried to run our own pipeline with the debug mode.

              We tried to use the camera on a mac and a jetson but on both it was not working.

              Important to note. Running this C++ example worked example/video_mobilenet. So I suppose that it is directly related to the color camera itself.

              As we bought through a japanese retailer we will try to return the camera to them. But as we had this issue twice, It might be interesting investigating it.

              Thanks for your help

                Hi,
                I had the same issue of Camera not detected on socketand Erik helps me
                The solution is to update depthai version:

                pip3 install depthai==2.22.0.0.dev0+874b317ab526d91dde84b68d756334a338d4da58 --extra-index-urlhttps://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local

                And run again the depthai-python/utilities/cam_test.py script

                In addition I created a distilled code for connecting the two rgb cameras and save one image from each camera, maybe it will be useful for someone, just as a sanity check:

                import cv2
import time
import time
import depthai as dai

# Params
target_path = 'PUT YOUR TARGET PATH FOR SAVING THE IMAGES HERE'
cam_list = ['rgb', 'camd']
cam_socket_opts = {
    'rgb'  : dai.CameraBoardSocket.CAM_A,
    'camd' : dai.CameraBoardSocket.CAM_D,
}

# Start defining a pipeline
pipeline = dai.Pipeline()
control = pipeline.createXLinkIn()
control.setStreamName('control')

cam = {}
xout = {}
streams = []
tofConfig = {}
for c in cam_list:
    xout[c] = pipeline.createXLinkOut()
    xout[c].setStreamName(c)
    streams.append(c)
    
    cam[c] = pipeline.createColorCamera()
    cam[c].isp.link(xout[c].input)
    cam[c].setBoardSocket(cam_socket_opts[c])
    control.out.link(cam[c].inputControl)
    print(f'Camera {cam_socket_opts[c]} connected')

# Pipeline is defined, now we can connect to the device
device = dai.Device.getDeviceByMxId('')
dai_device_args = [pipeline]
if device[0]:
    dai_device_args.append(device[1])

with dai.Device(*dai_device_args) as device:
    q = {}
    for c in streams:
        q[c] = device.getOutputQueue(name=c, maxSize=1, blocking=False)

    # Save frames
    print('Save one image from each camera')
    for c in streams:
        time.sleep(2.2) # wait for camera set up
        try:
            pkt = q[c].tryGet()
            frame = pkt.getCvFrame()
            cv2.imwrite(f'{target_path}/{c}.jpg', frame)
        except Exception as e:
            print(e)
