Image transport Framerate / processing overhead issue #130

Open ghost opened 5 years ago

ghost commented 5 years ago

Hi, We have written a ROS driver for the Point Grey Blackfly S (and other) cameras using the Spinnaker SDK. For a while image transport didn't work with their SDK, so we were using the standard transport for publishing image messages. However, now we are able to use Image transport but we noticed that our frame rate drops significantly.
If we try to run our system at 60 Hz, we can only deliver images at 40Hz even when just using raw. Does anyone have any ideas if the Image transport increases overhead enough to cause an issue like this?

Thanks in advance.
