Oak Poe 1 camera disconnection error

martin181818

Hi all,

I am using OAK Poe 1 camera. A simple script just to display the images (a while true loop).
During the execution of the script and if the camera is disconnected I get this error: Monitor thread - ping was missed, closing the device connection.
but the problem is that I am not able from inside the while loop to detect that camera is disconnected to execute the tasks I ned to implement in case of camera disconnection. What should I do to able to follow if the camera is connected or no even if the code is inside the while true loop to display images ?

Thank you very much

Hi @martin181818
Check if these change:

print(device.getDeviceInfo().state)
print(device.getDeviceInfo().status)

Or wrap the loop in try except RuntimeError:

qRgb = device.getOutputQueue("rgb", 1, False)

while True:
    try:
        print(device.getDeviceInfo().state)
        print(device.getDeviceInfo().status)
        inRgb = qRgb.tryGet()  # blocking call, will wait until a new data has arrived
        # Retrieve 'bgr' (opencv format) frame

        if inRgb is not None:
            cv2.imshow("rgb", inRgb.getCvFrame())
    except RuntimeError as e:
        ## your logic
        break

    if cv2.waitKey(1) == ord('q'):
        device.close()
        break

Thanks,
Jaka
