Line Scan Camera not detected in Pypylon

[SMA2016a]

Would post the IP address and subnetmask of the camera and network card.

[camron-musashi]

Camera:
IP: 192:168:2.21:3956
Subnet mask: 255.255.255.0

Network Card:
IPv4: 192.168.1.99
Subnet Mask: 255.255.0.0

[SMA2016a]

The camera must be findable using unicast communication.
The Subnet not mating each other.

Camera:
IP: 192:168:1.21:3956
Subnet mask: 255.255.255.0

Network Card:
IPv4: 192.168.1.99
Subnet Mask: 255.255.255.0

or

Camera:

Subnet mask: 255.255.0.0

Network Card:

Subnet Mask: 255.255.0.0

Changed camera's Subnet mask to match computers, and now connects. However image grab is not working.

ip_address = '192.168.2.21:3956'
subnet_mask = '255.255.0.0'

factory = pylon.TlFactory.GetInstance()
ptl = factory.CreateTl('BaslerGigE')
empty_camera_info = ptl.CreateDeviceInfo()

empty_camera_info.SetPropertyValue('IpAddress', ip_address)
empty_camera_info.SetPropertyValue('SubnetMask', subnet_mask)

camera_device = factory.CreateDevice(empty_camera_info)
camera = pylon.InstantCamera(camera_device)
camera.Open()
print("Using device ", camera.GetDeviceInfo().GetModelName())
camera.Height.SetValue(height)

camera.TriggerSelector.Value = 'FrameStart'
camera.TriggerMode.Value = 'On'
camera.TriggerSource.Value = 'Software'

camera.StartGrabbingMax(countOfImagesToGrab)
camera.TriggerSoftware.Execute()
print('Camera triggered')
print("starting capture")

actuatorThread = myThread("Actuator-thread", 1)
actuatorThread.start()

#don't grab any images until enought time has passsed for the first frame of the line scan to come through
#convert exposure from us to s
timeDelay = (exp / 1000000) * height
time.sleep(timeDelay)

while camera.IsGrabbing():
    print('Grabbing')
    result = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)
    if result.GrabSucceeded():
        image = result.Array
        result.Release()
        path = "C:\\Users\\camron.sabahi-pourka\\Desktop"
        cv2.imwrite(path + "\\light_1.bmp", image)
        print("Image saved successfully.")
        break
    if not result.GrabSucceeded():
        print('Grab failed')
    result.Release()

Hi,
can you provide the output of your script? What is not working exactly?
Best Regards

[camron-musashi]

The grabs were all failing/time out-ing/crashing my computer.

Type Time Source Message
Error 2024-03-20 13:31:26.314 Basler raL4096-24gm (23861554) Image acquisition on "Basler raL4096-24gm (23861554)" failed! Error: "The buffer was incompletely grabbed. This can be caused by performance problems of the network hardware used, i.e., the network adapter, switch, or Ethernet cable. Buffer underruns can also cause image loss. To fix this, use the pylonGigEConfigurator tool to optimize your setup and use more buffers for grabbing in your application to prevent buffer underruns."

This is what I would get when I try to capture a frame on Pylon Viewer. Very weird because I wasn't getting these errors in the previous days I was using the camera

[HighImp]

Have you tried the GigE-Configurator in the Pylon Viewer?

[camron-musashi]

Yes. However, when we would click the configuration button it would just close the window

[SMA2016a]

Does your script work, if you do not write the image to hardware?

[camron-musashi]

Yes the script works, and I'm able to connect to the camera however now I get this error
_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 1036)

This is my code

ptl = factory.CreateTl('BaslerGigE')
empty_camera_info = ptl.CreateDeviceInfo()

empty_camera_info.SetPropertyValue('IpAddress', ip_address)
empty_camera_info.SetPropertyValue('SubnetMask', subnet_mask)

camera_device = factory.CreateDevice(empty_camera_info)
camera = pylon.InstantCamera(camera_device)

#Camera Setup for capturing
countOfImagesToGrab = 10
camera.Open()
print("Using device ", camera.GetDeviceInfo().GetModelName())
camera.Height.SetValue(height)
camera.PixelFormat.Value = "Mono8"
camera.TriggerSelector.Value = 'FrameStart'
camera.TriggerMode.Value = 'On'
camera.TriggerSource.Value = 'Software'
# camera.MaxNumBuffer.Value = 5
# camera.AcquisiutionMode.Value = 'Single Frame'
# camera.AcquisitionStart.Execute()

camera.StartGrabbingMax(countOfImagesToGrab)
camera.TriggerSoftware.Execute()
print('Camera triggered')
print("starting capture")

actuatorThread = myThread("Actuator-thread", 1)
actuatorThread.start()

#don't grab any images until enought time has passsed for the first frame of the line scan to come through

timeDelay = (exp / 1000000) * height
time.sleep(timeDelay - 1.5)
degPerS = velocity / (16*14) * 1.8
imagingTime = int(360 // degPerS)
print(imagingTime)

while camera.IsGrabbing():
    print('Grabbing')
    result = camera.RetrieveResult(6000, pylon.TimeoutHandling_ThrowException)
    if result.GrabSucceeded():
        image = result.Array
        result.Release()
        path = "C:\\Users\\camron.sabahi-pourka\\Desktop"
        cv2.imwrite(path + "\\light_2.bmp", image)
        print("Image saved successfully.")
        result.Release()
        camera.StopGrabbing()
        camera.Close()
        break
    if not result.GrabSucceeded():
        print('Grab failed')
        result.Release()
        camera.StopGrabbing()
        camera.Close()
        print('Camera closed and grabbing stopped')
    result.Release()

result.Release()
camera.StopGrabbing()
camera.Close()```

[SMA2016a]

remove this line
ptl = factory.CreateTl('BaslerGigE')

try this:

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))

[SMA2016a]

@camron-musashi did you try this?

[camron-musashi]

Yes I did. For some reason I have no issues one on computer, however on the other computer (exact same computers) it throws errors and often crashes the computer. The computer shows issues both with pypylon and the Pylon Viewer GUI, but it was installed to have the packages needed for USB and gigE.
