This PR is for part 1 of #1354. It focuses on adding a model selection interface for models that exist in `photonvision_config/models/`. Upon completion we can ship more than 1 model and users could upload their own through `ssh` without deleting the shipped model. This PR also adds the abstractions need to support more DNN backends (say OpenCV, or RPI AI Kit) Up next is adding a CRUD interface for managing models through the UI.
PhotonVision
PhotonVision is the free, fast, and easy-to-use computer vision solution for the FIRST Robotics Competition. You can read an overview of our features on our website. You can find our comprehensive documentation here.
The latest release of platform-specific jars and images is found here.
If you are interested in contributing code or documentation to the project, please read our getting started page for contributors and join the Discord to introduce yourself! We hope to provide a welcoming community to anyone who is interested in helping.

Documentation
- Our main documentation page: docs.photonvision.org
- Photon UI demo: demo.photonvision.org (or manual link)
- Javadocs: javadocs.photonvision.org (or manual link)
- C++ Doxygen cppdocs.photonvision.org (or manual link)
Building
Gradle is used for all C++ and Java code, and NPM is used for the web UI. Instructions to compile PhotonVision yourself can be found in our docs.
You can run one of the many built in examples straight from the command line, too! They contain a fully featured robot project, and some include simulation support. The projects can be found inside the photonlib-java-examples and photonlib-cpp-examples subdirectories, respectively. Instructions for running these examples directly from the repo are found in the docs.
Gradle Arguments
Note that these are case sensitive!
-PArchOverride=foobar: builds for a target system other than your current architecture. Valid overrides are:- linuxathena
- linuxarm64
- arm64
- x86-64
- x86
-PtgtIp: Specifies where./gradlew deployshould try to copy the fat JAR to-Pprofile: enables JVM profiling
Out-of-Source Dependencies
PhotonVision uses the following additonal out-of-source repositories for building code.
- Base system images for Raspberry Pi & Orange Pi: https://github.com/PhotonVision/photon-image-modifier
- C++ driver for Raspberry Pi CSI cameras: https://github.com/PhotonVision/photon-libcamera-gl-driver
- JNI code for mrcal: https://github.com/PhotonVision/mrcal-java
- Custom build of OpenCV with GStreamer/Protobuf/other custom flags: https://github.com/PhotonVision/thirdparty-opencv
- JNI code for aruco-nano: https://github.com/PhotonVision/aruconano-jni
Additional packages
For now, using mrcal requires installing these additional packages on Linux systems:
sudo apt install libcholmod3 liblapack3 libsuitesparseconfig5
