GigE camera grab timeout using pypylon

[thedim-witted]

Hi, I am using Ubuntu 20 where I am able to see and capture frames from my acA1920-40gc camera using the Pylon Viewer but I am getting the below error when I am trying to capture it using a python script and pypylon.

__Traceback (most recent call last): File "test_gige.py", line 28, in res = cam.GrabOne(10000) File "/usr/local/lib/python3.8/dist-packages/pypylon/pylon.py", line 3604, in GrabOne return _pylon.InstantCamera_GrabOne(self, *args) _genicam.TimeoutException: Grab timed out. : TimeoutException thrown (file 'InstantCameraImpl.h', line 1362) __

This is the code used to grab:

from pypylon import pylon import cv2

#ip_address = '192.168.1.40' #info = py.DeviceInfo() #info.SetPropertyValue('IpAddress', ip_address)

#camera = py.InstantCamera(py.TlFactory.GetInstance().CreateFirstDevice(info))

#tlf = py.TlFactory.GetInstance() #camera = py.InstantCamera(tlf.CreateFirstDevice()) #camera.Open() #camera.StreamGrabber.DestinationPort = 50100 #res = cam.GrabOne(1000)

tlf = pylon.TlFactory.GetInstance() tl = tlf.CreateTl('BaslerGigE') cam_info = tl.CreateDeviceInfo() cam_info.SetIpAddress('192.168.1.40') cam = pylon.InstantCamera(tlf.CreateDevice(cam_info)) #cam.StreamGrabber.DestinationPort = 50100

#print(cam.getModelname()) #print(cam.getMacAddress())

cam.Open() #cam.StreamGrabber.DestinationPort = 50100 res = cam.GrabOne(10000)

print(res)

Please help in resolving this.

do you also set the IP address in pylon viewer manually? If not.. grab.py should just work

[SMA2016a]

can you ping your camera?

[thedim-witted]

@thiesmoeller Yeah. We have to set the IP address so that we access the same camera every time @SMA2016a acA1920-40gc

[SMA2016a]

do you use "Add remote GigE Camera" in Pylon viewer?

Would you try this?

ip_address = '192.168.1.40'

tlf = pylon.TlFactory.GetInstance()
tl = tlf.CreateTl('BaslerGigE')     # remove this line
cam_info = tl.CreateDeviceInfo()  #replace this with following line
cam_info = pylon.DeviceInfo()   
cam_info.SetIpAddress(ip_address)
cam = pylon.InstantCamera(tlf.CreateDevice(cam_info))

if above code does not resolve the issue

try this.

ptl_GigE = tlf.CreateTl('BaslerGigE')
ptl_GigE.RenounceRemoteDevice(ip_address)

I'm also experiencing the same issue.

Ubuntu 20.04 a2A5328-4gcPRO

Here is my code snippet

from pypylon import pylon

ip_address = '192.168.0.4'
tlf = pylon.TlFactory.GetInstance()
tl = tlf.CreateTl('BaslerGigE')
cam_info = tl.CreateDeviceInfo()
cam_info.SetIpAddress(ip_address)
camera = pylon.InstantCamera(tlf.CreateDevice(cam_info))
cam_info = camera.GetDeviceInfo()
print(
    f"Name: {cam_info.GetModelName()}",
    f"IP: {cam_info.GetIpAddress()}",
    f"Mac: {cam_info.GetMacAddress()}"
)

camera.Open()
print("Camera opened")
camera.GrabOne(1000)
camera.Close()

It shows the correct model and mac address. It works fine in Pylon Viewer as well as in my C++ code. What could be the problem?

[SMA2016a]

@hutomosaleh have you tried the code that I have posted?

Hello @SMA2016a

I'm experiencing the same problem but I'm not sure to understand what you are asking to test. I'm executing the code from a virtual machine in another network but I'm able to ping the camera. This is the code I'm executing:

from pypylon import pylon

ip_address = '10.1.200.13'


factory = pylon.TlFactory.GetInstance()
ptl = factory.CreateTl('BaslerGigE')
empty_camera_info =ptl.CreateDeviceInfo()
empty_camera_info.SetPropertyValue('IpAddress', ip_address)
camera_device = factory.CreateDevice(empty_camera_info)
camera = pylon.InstantCamera(camera_device)
camera.Open()

numberOfImagesToGrab = 100
camera.StartGrabbingMax(numberOfImagesToGrab)

while camera.IsGrabbing():
    grabResult = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)

    if grabResult.GrabSucceeded():
        # Access the image data.
        print("SizeX: ", grabResult.Width)
        print("SizeY: ", grabResult.Height)
        img = grabResult.Array
        print("Gray value of first pixel: ", img[0, 0])

    grabResult.Release()
camera.Close()

I'm getting the following error:

  return _pylon.InstantCamera_RetrieveResult(self, *args)
_genicam.TimeoutException: Grab timed out. Possible reasons are: The image transport from the camera device is not working properly, e.g., all GigE network packets for streaming are dropped; The camera uses explicit triggering (see TriggerSelector for more information) and has not been triggered; Single frame acquisition mode is used and one frame has already been acquired; The acquisition has not been started or has been stopped. : TimeoutException thrown (file 'InstantCameraImpl.h', line 1037)

Hello @bsteenput Did you manage to solve this issue?

[SMA2016a]

remove this line

ptl = factory.CreateTl('BaslerGigE')

Hi @JoaqBS ,

I am currently using a camera that is located on a different network than my machine. In order to establish a connection, I need to be able to specify the camera's IP address. Interestingly, I have noticed that the same code works flawlessly on a machine that is on the same network as the camera, and even the pylon viewer is able to retrieve pictures.

Upon investigating the issue using Wireshark, I found that while the camera is receiving all instructions and is able to send back its configuration, it is sending the UDP data stream back to 0.0.0.0.

I reached out to Basler support, and they recommended using CBaslerUniversalInstantCamera. I tried out the Grab_MultiCast.cpp sample code in the pylon SDK and tested the feature, and it works perfectly.

My question now is: is it possible to achieve the same functionality in pypylon?

[SMA2016a]

set camera to multicast mode and then set the destination address.

cam.StreamGrabber.TransmissionType ="Multicast" cam.StreamGrabber.DestinationAddr ="IP of your target PC"

[Raistlin707]

The cam=pylon.InstantCamera(...) object doesn't seem to be able to grab if initilialized using tl.CreateDevice + IP address. I don't know why. The good part is that using the fullname instead of the IP address should be ok.

Having only the camera's IP as input, you can try a workaround like this :

# Create cam using an IP
tlf = pylon.TlFactory.GetInstance()
tl = tlf.CreateTl('BaslerGigE')
cam_info_using_ip = tl.CreateDeviceInfo()
cam_info_using_ip.SetIpAddress('192.168.1.40')
cam_unable_to_grab = pylon.InstantCamera(tlf.CreateDevice(cam_info_using_ip))

# Get fullname
fullname = cam_unable_to_grab.GetDeviceInfo().GetFullName()

# Create cam using fullname
cam_info_using_fullname = tl.CreateDeviceInfo()
cam_info_using_fullname.SetFullName(fullname)
cam_able_to_grab = pylon.InstantCamera(tlf.CreateDevice(cam_info_using_fullname))

cam_able_to_grab.Open()
res = cam_able_to_grab.GrabOne(10000)

[SMA2016a]

I have already posted a possible solution, that is

ip_address = '192.168.1.40'

tlf = pylon.TlFactory.GetInstance() cam_info = pylon.DeviceInfo()
cam_info.SetIpAddress(ip_address) cam = pylon.InstantCamera(tlf.CreateDevice(cam_info))

Simply use the universal device info object instead of GigE one.

BTW: GigE Device object is depreciated too.

[Raistlin707]

Hi @SMA2016a

Thanks for your help! When I tried your solution earlier, i forgot to replace "CreateDeviceInfo" into "DeviceInfo" which resulted into an Exception. Your solution is indeed way better than the one I posted yesterday.

[SMA2016a]

Thanks for the update

Hi,

I came to this thread because I get an exception when I want to grab an image from a Basler acA1300, although I am able to find the camera using the depreciated Device object. It throws the following exception: Grab timed out. Possible reasons are: The image transport from the camera device is not working properly, e.g., all GigE network packets for streaming are dropped; The camera uses explicit triggering (see TriggerSelector for more information) and has not been triggered; Single frame acquisition mode is used and one frame has already been acquired; The acquisition has not been started or has been stopped. : TimeoutException thrown (file 'InstantCameraImpl.h', line 1037)!

So I decided to change to my code to the one posted above unfortunately now I get an Error that now device is available: _genicam.RuntimeException: No device is available or no device contains the provided device info properties. : RuntimeException thrown (file 'TlFactory.cpp', line 694)

I am using a docker container (python 3.10) with pypylon installed. The camera got an static IP and I started the container with --network:host and mapped /dev:/dev. Between the device running the container and the camera is a PoE switch to power this camera and several others.

Now I'm confused if this is an Docker problem or if this is something with my code/setup or do I have to set specific parameters on the camera to get image to the container.

Hi, thanks to all for the clues on solving the issue here.

I had to do the following:

tlf = pylon.TlFactory.GetInstance()
tlf.EnumerateDevices() # Note this additional line to @SMA2016a's answer above
cam_info = pylon.DeviceInfo()
cam_info.SetIpAddress(ip_address)
cam = pylon.InstantCamera(tlf.CreateDevice(cam_info))

And then it worked.

Without enumerating devices, I got the error No device is available or no device contains the provided device info properties.

I would like to get to the bottom of why exactly, if anyone can enlighten me here.

Cheers!
