I am having a strange issue with calibration. When I try to start the calibration, I get an error message saying “no camera selected.” I’ve seen this message before and usually turning the cameras off and back on again does the trick. That did not fix things this time. What makes it weird though is that if I go to the GenICam node to select a camera, both cameras are shown in the dropdown menu even after refreshing the list. I also tried unplugging just one of the cameras, and the list only showed the one camera that was still plugged in. I’ve already tried restarting everything including the software and the computers.
Pre-release 3.4 version had asynchronous loop that continuously updated list of cameras. We had issues with it (crashes during calirbation) and disabled it. Now list of cameras are refreshed only on start and when manually pressed the update camera list button.
For next minor release we want to fix it to automatically refresh cameras list when camera node initializes and when calibration starts.
The node remembers camera by its name and serial number. It forbids to use the same camera in 2 or more nodes. If you have 2 cameras connected to ethernet and powered on, press update camera list in camera node and select camera for each node using “SelectedCamera” parameter. This should work.
