Reconnecting to an disconnected camera inside python

KoenvanWijlick

Hello,

i am trying to implement code inside my project that tries to reconnect to the camera without powering off the camera. Is there a way to achieve this. i have tried below code but it doesnt work:

try:

         `Coords_list, frame, cameradata = self.Camera.processImage()  # This is the luxonis camera`

except RuntimeError as e:

print(f"Camera error: {e}")

time.sleep(5)

try:

self.Camera = Objectdetection()

print("Camera reconnected")

except Exception as reconnection_error:

print(f"Failed to reconnect: {reconnection_error}")

And i get the following error when running this code, is there a way to reconnect to the camera?

Hi KoenvanWijlick
You can use this logic to reconnect to a device.

device.startPipeline(pipeline)
# random host side code/loop

device.close()

then just use startpipeline() to reconnect to it again. Without first closing the device, it is not possible to reconnect to it since only one pipeline can run on it at a time.
Not sure why you would need that anyway.

Thanks,
