Photonvision

PhotonVision is a free, open source computer vision system built for the FIRST Robotics Competition. Teams download an image for a supported coprocessor and can begin tracking targets within minutes, without needing deep vision expertise or a large budget. The feature set covers the tasks robot teams commonly need. It includes AprilTag support, built in camera calibration that computes per camera intrinsics for accuracy, and multi tag pose estimation that fuses all available data to locate the robot. A machine learning feature runs hardware accelerated inference for detecting game pieces, and a conference talk on the site covers object detection on the Rubik Pi 3. A driver mode lets a team use the same camera for driving and for robot vision, and the system can run as many cameras at once as the hardware allows. It is intended for student robotics teams and their mentors. The project is developed openly on GitHub by a community of contributors and is released under the GNU GPL v3 license, which allows downloading, modifying and sharing the source code. Documentation, a Discord community and a demo are linked from the home page. The software is free to use and the site publishes no paid plans.
