How to use

After you run the last command in the installation section, a window should open with live footage of your DepthAI device.

The finding process wil start right after the script starts. After that, it will wait 3 seconds before starting again. You can check if it found a license plate in the console

FAQs

Can I run this on Windows?

Yes. With Oracle VM VirtualBox and the VirtualBox Extension pack, you can run Linux in a virtual machine and give the VM access to the USB port holding the DepthAI device. Just install a Linux distrubution of your choice in the VM and follow the steps in the installation section

What do I do if I get an error bash: git: command not found or bash: python: command not found or bash: apt: command not found?

bash: git: command not found and bash: python: command not found: That means you need to install Git and Python via APT or your other package manager

bash: apt: command not found: Different Linux distros have different package managers. Debian, Ubuntu, and macOS use APT. Fedora, CentOS, and RedHat use Yum. Alpine Linux uses Pacman. openSUSE uses Zypper. To install the packages, run the APT commands above and replace apt with yum or pacman or zypper.
