Hi, it seems to be a QT problem.

We tested this repo on Ubuntu16 and Ubuntu18, which have the QT5 embedded. Are you using Ubuntu20.04 or higher? I haven't tested it on Ubuntu20+ where the default QT may not be QT5. You can check it.

If this problem is here. You can use this repo on older Ubuntu, or try installing QT5 on your PC.

I am running into the same issue on Ubuntu 20.04, this is likely an issue with VTK-7, see these issues 1, 2

As a workaround, I suggest compiling the ROS components and QT components separately. Just uncomment this line and build separately from ROS in src/calibrator
