Please execute one of the following command snippets in the new terminal. Note that I have previously applied PR58 manually and still observed the issue with the ZED2/zed_ros2_wrapper/ROS2-foxy. to go from compressedDepth to raw. I reverted to the "original" image_transport_plugins package available with sudo apt install ros-foxy-image-transport-plugins to verify what happens when advertizing the image topics and I noticed this: at the very beginning, the error is not supported then it becomes parameter 'format' has already been declared, indeed if you look in the params list there is a format parameter. Since rospy does not support compressedDepth (as far as I know) I am using rosrun image_transport republish to go from compressedDepth to raw. Build and install the zed-ros2-wrapper, for example: Build and install image_transport_plugins. As of Diamondback, this stack has a stable ROS API. I see the same problem with image_transport::create_subscription() and using ComposableNode(, remappings=[]). CameraPublisher is a convenience class for publishing synchronized image and camera info topics using the standard topic naming convention, where the info topic name is "camera_info" in the same namespace as the base image topic.. remappings works fine, however, when using rclcpp::Node::create_subscription().

When you find the missing step, please write it in the comment or edit it in the questions. A popular ROS 1 package actionlib creates 5 topics with the same namespace. I notice that the rate at which the camera sensor provides the frames is 30 fps but the frame rate returned by "ros2 topic hz" is comparatively quite low, that is . I have the latest version installed, and I do the following: $ ros2 topic list /bar /foo /parameter_events /rosout OK, a couple of left-over topics (how do I flush everything out?) It enables any node using image_transport classes to publish and subscribe to compressed image topics. Fixed CMakeLists.txt for Dashing. ros2_v4l2_camera is a C++ library. ros2 run image_transport republish raw --ros-args --remap in:=/b/image_raw --remap out:=/b/image_comp, Passes out: the CompressedPublisher publish method accepts a normal Image, compresses the image, and then pushes it to. Now we need to add the "dummy" link called camera_link_optical mentioned earlier, to account for the different coordinate standards - transforming from the standard ROS robot orientation (x-forward, y-left, z-up) to the standard optical orientation (x-right, y-down, z-forward).. For a camera link called camera_link, the following block achieves this and can be . advertise () returns an image_transport::Publisher object, which serves two purposes: 1) it contains a publish () method that lets you publish images onto the base topic it was created with, and 2) when it goes out of scope, it will automatically unadvertise.

Once it's working, use this ROS2 driver instead of the ROS1 one. Continuous Integration: 25 / 25. In just a few lines of code, we have written a ROS image viewer that can handle images in both raw and a variety of compressed forms. When launching the zed-ros2-wrapper with the image_transport_plugins installed, the below errors are observed and compressed image topics are not available. ROS1/ ROS2 -based industrial applications [6 - 9]. This is a ROS2 Foxy bug that they have just solved but it has not yet been merged in the repository. Usage. You can: Rewrite the driver node in ROS2. Already on GitHub? the CompressedPublisher publish method accepts a normal Image, compresses the image, and then pushes it to publish_fn(compressed); Before I try to somehow manually do the same publish call, i just want to be sure if this is even implemented in ROS2? Thanks to the ros1_bridge, the new ROS2 driver will be able to communicate with the ROS1 image processing node, and all other ROS1 nodes in the app. I think I have an "answer", or at least some sort of working usage. I continue to investigate the problem to try to understand if it is possible to fix it.

Do you observe the same @Myzhar? If you want to view a compressed image stream (usually a good idea over wireless!) A normal image_transport::Publisher also has no methods accepting a sensor_msgs::msg::CompressedImage. For example, if theora_image_transport is built on the publisher's side, you can use theora transport: rosrun image_view image_view image:=/camera/image theora but I later realized that won't work.
