Publishing Images #63

Hello,

publish

I am trying to calibrate my camera using the Kalibr Toolbox and utilizing the video_stream_opencv to record a ROS bag. I am trying to achieve a publish rate of about 2 images per 0.01 seconds while also accounting for the delay from converting the images to grayscale. Here is an image above from an example dataset from Kalibr that shows what I am trying to do. What values do I need to modify in the launch file to achieve a similar publish rate as shown above?

Or better yet, are there any other ROS nodes that publishes images in grayscale w/o delay?
