Problem connecting to pylon(basler) camera

Pal_ani

Hi there. I am trying to access Basler Pylon camera through an application using Qt. But i am having problem in connecting the camera.
Presently my .pro file looks like:

The logs in the application output says:
=>LOG : : SetGenICamLogConfig(path) not called, and environment variable GENICAM_LOG_CONFIG_V3_0 not found. Using default logging configuration.
=>LOG : : Cannot open logger parameter file 'C:/Program Files/Basler/pylon 5/log/config/DefaultLogging.properties'
=>LOG : : Default logger parameter file '$(GENICAM_ROOT)/log/config/DefaultLogging.properties' not found

I am using MSVC2017_64bit compiler.

Any help regarding the issue is welcome.

Hi and welcome to devnet,

Do you have the same trouble if you run the pylon application ?

Pal_ani

@SGaist No, it works fine with Pylon Viewer. I can capture images and videos. The problem is when I want to access the camera using Qt.

Have you tried setting the GENICAM_LOG_CONFIG_V3_0 environment variable to (I assume) a path for the log file?

Pal_ani

@mranger90 No I haven't. Can you please tell me how to do it?

mranger90

It depends on your OS. Since you use the MSVC compiler I guess I can assume its windows.
In that case you can add an environment variable from the System/Advanced System Settings/Environment Variables.
I'd check the docs for the camera's SDK. There may be other things that need to be set.
Does the Windows camera app connect to it ?

@mranger90 Hi, I haven't been able to solve the problem yet. Can you help? I know how to add environment variable in my OS (Windows 10), but how do I find the path of the GENICAM_LOG_CONFIG_V3_0 environment variable .

SGaist

You can set the value yourself so you know where the file is.

Have you solved this problem yet?
I had the same problem.

I'm trying to add environment variables,but have no use.

C:\ProgramData\GenICam\xml\cache is path.

While using pylon 6.2 you can also set an empty environment variable.

export GENICAM_LOG_CONFIG_V3_1 = ""
