Linux PC Installation

PhotonVision may be run on a Debian-based Linux Desktop PC for basic testing and evaluation.

Note

You do not need to install PhotonVision on a Windows PC in order to access the webdashboard (assuming you are using an external coprocessor like a Raspberry Pi).

Installing Java

PhotonVision requires a JDK installed and on the system path. JDK 11 is needed (different versions will not work). If you don’t have JDK 11 already, run the following to install it:

$ sudo apt-get install openjdk-11-jdk

Warning

Using a JDK other than JDK11 will cause issues when running PhotonVision and is not supported.

Downloading the Latest Stable Release of PhotonVision

Go to the GitHub releases page and download the relevant .jar file for your coprocessor.

Note

If your coprocessor has a 64 bit ARM based CPU architecture (OrangePi, Raspberry Pi, etc.), download the LinuxArm64.jar file.

If your coprocessor has an 64 bit x86 based CPU arcitecture (Mini PC, laptop, etc.), download the Linuxx64.jar file.

Warning

Be careful to pick the latest stable release. “Draft” or “Pre-Release” versions are not stable and often have bugs.

Running PhotonVision

To run PhotonVision, open a terminal window of your choice and run the following command:

$ java -jar /path/to/photonvision/photonvision-xxx.jar

If your computer has a compatible webcam connected, PhotonVision should startup without any error messages. If there are error messages, your webcam isn’t supported or another issue has occurred. If it is the latter, please open an issue on the PhotonVision issues page.

Accessing the PhotonVision Interface

Once the Java backend is up and running, you can access the main vision interface by navigating to localhost:5800 inside your browser.
