You seem to be importing a C header and use it as if it was containing C++ classes. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. DEPENDENCIES sensor_msgs I know that ROS 2 . 'Cause it wouldn't have made any difference, If you loved me. a given value at the given point position interpreted as the datatype specified by the given datatype parameter. "srv/Detectron.srv" How to add sensor_msgs.msg type in my ros system? a given value at the given point position interpreted as the datatype specified by the template argument point_field_type. I wrote a simple point cloud subscriber and used it to test simulation speed.

I noticed the comment that you have in that same file which says: So if you were worried by a data format conversion, I guess a full blown calculation to deproject a whole image may slow down the simulation even more. # will make fairly laser-specific assumptions about this data.

Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. If you are going to use the generate_msgs () macro to ensure message dependencies are built, you'll need a find_package call for message_generation, you'll also need to list message_runtime as a CATKIN_DEPENDS in your catkin_package macro. The bug is that tf2_bullet publicly depends on tf2_ros::tf2_ros, but does not tell downstream packages to find_package(tf2_ros) to get access to that target. Find centralized, trusted content and collaborate around the technologies you use most. Can you guide me on that. To learn more, see our tips on writing great answers.

Just look at the fifth line of your error log: To solve this simple issue, just add the dereference operator (*) to that pointer: I assume that there are no other errors in the code. The other thing to check is to make sure that geometry_msgs is properly located in your ROS_PACKAGE_PATH. Get from Webots a PointCloud2 measure instead of computing it for the RangeFinder, Webots Discord technical-questions channel, https://github.com/cyberbotics/webots_ros2/blob/master/webots_ros2_driver/src/plugins/static/Ros2RangeFinder.cpp, Compute RangeFinder point cloud in Webots, Similar as above, but instead of relying on, Instead of doing the deprojection calculations in a Python.
