Error connecting to Basler ACE 2 Pro

[tobias-fleck-fzi]

Hello,

I have issues running a basler ace 2 pro (a2A1920-51gcPRO) camera with the driver. I'm using ros noetic on 20.04.
The error log shows that the property ExposureTimeAbs cannot be queried from the camera.

what(): Error while accessing ExposureTimeAbs in PylonGigECamera

When I use the ./PylonViewerApp, I can access the camera and even view a video stream, so the cam in general seems to be working.
After I tried the ros driver, the camera seems to freeze internally and does not show any video stream in ./PylonViewerApp anymore (ros nodes were already terminated properly).

Do you have any suggestions how to trace the problem? What did I do wrong?

thanks in advance for your help,
Tobias

@tobias-fleck-fzi Hi, please check #63. Your camera model is not yet supported by the current ROS driver. We are considering to update it on basis of pylon 6.x in order to support ace 2 GigE either (ace 2 USB work fine). I suppose, this will take some time till March/April ,21. Regards.

[tobias-fleck-fzi]

Thank you for your instant reply! Of course this explains the error. March/April sounds good for me. Is it possible to keep me updated regarding the ros support for ACE 2 pro, at least when where will be any delays?
Best Wishes, Tobias

Hello all,

What is the current status for this issue?
We want to use Ace2 cameras with ros and need a driver for it.
We had the same errors as @tobias-fleck-fzi
We were able to patch the current driver so that at least images are delivered. But we can't configure the camera and especially the exposure time.

Tanks in Advance

@michael1309 Hi, we are still working on that and hope to have some working implementation until end of April. Regards.
@pablo-quilez FYI.

Hello,

we updated on last Friday the pylon6-dev branch. This should solve the issue, as we upgrade the driver for the missing cameras. Please let me know if it is working properly.

Thanks and regards!

Hello,

I tested the new branch on ubuntu 20.04, pylon 6.2, with the mentioned ace 2 pro model above. The used commit was efc9932.

I was able to receive camera images from the driver and the driver seems to properly use all parameters I have given via config file so far.

Thanks for your awesome work!

Best wishes,
Tobias

Hello,

I am trying to run ace 2 Pro Basler camera with the pylon6-dev branch on ubuntu 20.04.
It was working fine until I had to configure the flashlight I/O parameters.
I want to use the startup_user_set parameter set to "Default" by the default, instead of "CurrentSetting", but when I do that camera fails to launch properly. It throws this error : Error applying cam specific startup setting for GigE cameras: Parameter not found in CFloatParameter::GetMax. (No node attached.). Do you know which parameter is a problematic one here?
