There's already a PR for this? (#118 )

hjed commented 5 years ago

Wrt to compression is this actually faster? Given that both the cameras and this code run on the nuc, I'd expect compression to make it slower.

YiweiHan commented 5 years ago

rqt was quoting rates of ~0.5Hz for raw images, and ~4-5Hz for compressed images. then again we were running rqt on groundstation so that may have affected something

hjed commented 5 years ago

Yeah from the gs if you're subscribed to it there it will be much faster. But the oposite is true for the nuc.

hjed commented 5 years ago

But if you want to use compression you should use image transport http://wiki.ros.org/image_transport

Closing this in favour of #124
