Hi,

I'm trying to run "openalpr-utils-calibrate" in VM (running the cloud version" and I get "(Adjust OpenALPR Perspective:1011): Gtk-WARNING ***; cannot open display: Pure virtual method called - terminate called without an active exception"

Anyone know how to fix this?

Thanks!

The openalpr-utils-calibrate utility requires a GUI to run. You could use the Windows version (https://github.com/openalpr/openalpr/releases/download/v2.2.0/openalpr-2.2.0-win-64bit.zip) and then copy-paste the calibration configuration settings into your Linux VM.

Apparently I'm thicker than Donnie. I was able to run the windows version of the calibration tool. and I get an ouput that is prewarp = planar, .....

How do I copy-paste the calibration. I tried a straight copy paste, but prewarp does not appear to be a command. What am I missing?

Thanks.

The config option is in /etc/openalpr/openalpr.conf

You can edit this file with:

sudo nano /etc/openalpr/openalpr.conf

And then replace the value for "prewarp = ..."

I'm working on making this whole process web-based, so hopefully it will be much easier in the future.
