Also, callback function runs every 0.1 seconds.

I believe this is incorrect. I see that you have made a self.r object but never used it anywhere in the code to achieve an update rate of 10hz. If you want to run the main loop at every 0.1 seconds, you will have to call your commands within the following loop (see rospy-rates) before calling rospy.spin():

QUESTION

ROS Melodic & OpenCV - CompressedImage not publishing

Asked 2018-Aug-11 at 10:29

I am new to ROS. I am playing with integrating OpenCV and ROS. The code I am using is inspired from the ROS tutorial on converting ROS messages to CV::mat and back.

I am subscribing to the topic /raspicam_node/image/compressed published by the raspicam node. I have no problem getting the topic, converting it to CV:mat, and modifying it with OpenCV. Line 32 opens a window and shows me the modified CV:mat image.

My issue comes at Line 36. I can see the topic using rostopic list but when I echo it nothing comes up. Same if I use rqt_image_view.

Any thoughts on what I am missing? Thank you!

If you check rostopic echo /modified_image you can see that your topic is successfully published.

rqt_image_view will display it if you call your published topic modified_image/compressed.

From the compressed_image_transport wiki:

publish it on a topic of the form image_raw/compressed. Then any ROS node using image_transport can subscribe to image_raw with transport compressed, just as if image_transport were used on the publisher side
