Re: Offboard Camera Processing?

We would also recommend against using Network tables for the purpose of sending images. That was NOT added to the network tables implementation since it is WAY quicker (i.e. a LOT less data) to send a jpg image over the network using standard HTTP queries. Sending an image uncompressed (or even compressed) using Network Tables is not what it is built for. It is meant for variables and command codes, not images.

If you want to process images on the Driver station get them directly from the Axis camera as .jpg images. That will give you the best bandwidth utilization. Even with that you'll still need to keep things small in order to get frequent images (i.e. 20+fps). If you need to use anything larger it may be best to use onboard computing and avoid the bandwidth throttling.
