Actual FPS per video stream as listed in the DS view should match set FPS for the stream as configured for that camera, if it does not, lower FPS and / or Resolution or increase compression until actual FPS and set FPS match and video quality and latency is acceptable.Power:, ensure 2.5+ amps of power are available to the Pi, especially if using 3-4 cameras and / or vision processing pipeline is in use.Compression: 30, adjust as needed to get desired cpu usage, bandwidth and clarity.FPS: 10-15, reduce as needed to lower Pi cpu usage or bandwidth.Recommended stream settings, per camera.FPS: 15-20, reduce as needed to reduce Pi cpu usage.Recommended hardware settings, per camera.Here are two 12 volt models that can be wired directly into a secondary VRM or PDP, if used with a 10 amp breaker.Onboard ethernet switch, allows for easier tethering and is required if you want to tether and use FRCVision at the same time.Any Linux UVC supported USB camera that supports MJPEG and desired resolution and fps in camera hardware:.Video processing, target acquisition and tracking.
No need to add code for basic camera streaming.Multiple language choices for vision processing pipeline.Ability to have a per camera vision processing pipeline.Ability to control Resolution, FPS and compression per camera feed.Ability to control stream from FRC shuffleboard and LabView Dashboard.Ability to handle more concurrent streams than a roboRIO.Lower video latency and higher frame rates due to increased cpu cycles available on Pi.
