# What is Vision?

Vision in FRC® uses a camera connected to the robot in order to help teams score and drive, during both the autonomous and teleoperated periods.

## Vision Methods

There are two main method that most teams use for vision in FRC.

### Streaming

This method involves streaming the camera to the Driver Station so that the driver and manipulator can get visual information from the robot’s point of view. This method is simple and takes little time to implement, making it a good option if you do not need features of vision processing.

### Processing

Instead of only streaming the camera to the Driver Station, this method involves using the frames captured by the camera to compute information, such as a game piece’s or target’s angle and distance from the camera. This method requires more technical knowledge and time in order to implement, as well as being more computationally expensive. However, this method can help improve autonomous performance and assist in “auto-scoring” operations during the teleoperated period. This method can be done using the roboRIO or a coprocessor such as the Raspberry Pi using OpenCV.
