The basic architecture of the cscore library is similar to that of MJPGStreamer, with functionality split between sources and sinks. This allows you to pass custom processed and/or annotated images to the dashboard. PutVideo(): Start a server that you can feed OpenCV images to. This allows you to get images from the camera for image processing on the roboRIO (in your robot code). GetVideo(): Get OpenCV access to a camera.

It also starts a server so the Axis stream can still be viewed when your driver station is connected to the roboRIO via USB (useful at competition if you have both the Axis camera and roboRIO connected to the two robot radio Ethernet ports). Even if you aren’t processing images from the Axis camera in your robot code, you may want to use this function so that the Axis camera appears in the Dashboard’s drop down list of cameras. Microsoft LifeCam) and starts a server for it so it can be viewed from the dashboard.ĪddAxisCamera(): Add an Axis camera. StartAutomaticCapture(): Add a USB camera (e.g. It uses a singleton pattern to maintain a database of all created cameras and servers.
It also is responsible for publishing information about the cameras and camera servers to NetworkTables so that Driver Station dashboards such as the LabVIEW Dashboard and Shuffleboard can list the cameras and determine where their streams are located.
The CameraServer class (part of WPILib) provides a high level interface for adding cameras to your robot code.
