How to manipulate the Camera Properties

[nmarc]

Hi ! and thank you four your great project.
I try to change the Camera Properties, but I fail.

The examples in the PylonSDK (C++) use
Camera = pTl->CreateDevice( devices[ 0 ] ); Camera.Open(); Camera.ExposureTimeRaw.SetValue( 500 );
but this does not work in Python.

may somebody please help me to modify the Brightness, Gain, Exposure-Time and Contrast ?
Thanks in advance
Marc

Marc have you fixed this already?
I'm having the same issue

Hi kwint,
i found a workarround.
you can load an full parameter set via *.pfs File.

Code Snippet:
`
valid, self._pGrabber = self._cam.connectGrabber()
print("GetDeviceInfo().GetSerialNumber = ", self._pGrabber.GetDeviceInfo().GetSerialNumber() )
grab= self._pGrabber.GrabOne(3000) # timeout von 3 sekunden
if not grab.GrabSucceeded():
print("GRAP ERROR !!! ")

print("Camera is online and ready for setup !")
self._cam.disconnectGrabber()
self._cam.loadPFSFile(path)
`

i build a Class like:
Code snippet:
`
class PylonCamera():
def init(self):
self.logger = logging.getLogger('PylonCamera')
self._tlfactory = pylon.TlFactory.GetInstance()
self._ptl = self._tlfactory.CreateTl('BaslerGigE')
self._convertMethode = None
self._pixelDataFormat = None
self._pGrabber = None

def connectGrabber(self):
# list devices
if (pylon.version == "1.2.0rc2+pylon5.0.12.11830" or pylon.version == "1.1.0+pylon5.0.11.10913"):
detected_devices = self._tlfactory.EnumerateDevices()# Bei der neuen Version wird das Enumerate über die Kamerainstanzs gemacht
else:
detected_devices = self._ptl.EnumerateDevices()# Bei der alten noch über den Transport Layer
self.logger.info("%i devices detected:" % len(detected_devices))

    self.logger.info([d.GetFriendlyName() for d in detected_devices])
    
    #exit if no devices found
    if(len(detected_devices) == 0):
        self.logger.error("ERROR -> No device")
        raise RuntimeError("keine brauchbare Kamera auf dem GeniCam Bus")
    if (pylon.__version__ == "1.2.0rc2+pylon5.0.12.11830" or pylon.__version__ == "1.1.0+pylon5.0.11.10913"):
        self._pDevice = self._tlfactory.CreateDevice(detected_devices[0])# In der neuen Version über die Instanz
    else:
        self._pDevice = self._ptl.CreateDevice(detected_devices[0]) # Bei der alten über den Transport Layer


    self._pGrabber = pylon.InstantCamera(self._pDevice)
    self.investigateImageConverter()
    
    
    return (True,  self._pGrabber)

def disconnectGrabber(self):
self._pGrabber.StopGrabbing()
self._pGrabber.Close()

def loadPFSFile(self, path):
"""
Load a PFS File to the Camera
:param path:
:return:
"""
self._pGrabber.Open()
pylon.FeaturePersistence.Load(path, self._pGrabber.GetNodeMap(), True)
self._pGrabber.Close()
time.sleep(0.3)

`

So you are able to manipulte the camera Settings.
You can export the *.pfs-File from the Basler-Camera with the pylon-Viewer.
Ist a verry simple file-format, so you can use a parser to generate an individual Setting on the fly.

I hope you can solve you task.

Danke. Sprechen sprescht nett destuch, but I appreciate the load definition. That will be most helpful.
