2021-04-16 02:10:54 -0500 | marked best answer | Subscribe to PointClud2 Ros2 Hello together I get a depth image from my intel d453 camera in a PointClud2 msgs. My problem is now the following. I do not understand how I can access the individual points, i.e. XYZ coordinates. It is only possible to access the whole data structure. Unfortunately it is not possible to sort the points correctly. I need the following information for each point XYZ coordinates Color of the point Is it possible to access the individual points within the data structure in this way? Here is my Subscriber Callback: Many thanks in advance! |
2021-04-16 02:10:21 -0500 | marked best answer | ROS 2 Subscribing to custom message type Hello, I use the following Intel package to run my Intel Ralsense cameras. https://github.com/IntelRealSense/rea... I am now trying to subscribe to the topics that are opened by the realsense2_camera_node. I am still quite new to ROS and don't see what exactly I am doing wrong. I have created a new package "tracking_pos" with which I want to subscribe the topic "/t265/accel/sample". The topic is published properly and I can view it with the command "ros2 topic echo" on the terminal. Below is my code CMakeList.txt Relevant sections from the Package.xml The project cannot be built like this. My question now is how to specify the data type in the subscriber correctly to receive the published data of the topic. Many thanks for the help in advance. |
