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

Install raspicam_node

A binary can be found at https://packages.ubiquityrobotics.com/ follow the instructions there to add the repository. Then run sudo apt install ros-kinetic-raspicam-node.
If you want to build from source instead of using the binary follow this section. This node is primarily supported on ROS Kinetic, and Ubuntu 16.04, and that is what these instuctions presume. Go to your catkin_ws cd ~/catkin_ws/src. Download the source for this node by running. There are some dependencies that are not recognized by ros, so you need to create the file /etc/ros/rosdep/sources.list.d/30-ubiquity.list and add this to it. Then run rosdep update. Install the ros dependencies,. Compile the code with catkin_make.

Support

Make sure that your user is in the video group by running groups|grep video. If you get an error saying: Failed to create camera component, make sure that the camera cable is properly seated on both ends, and that the cable is not missing any pins. If the publish rate of the image over the network is lower than expected, consider using a lower resolution to reduce the amount of bandwidth required.
