首先,在容器内创建一个新的ROS 2包: source/opt/ros/foxy/setup.bashmkdir-p~/ros2_camera/srccd~/ros2_camera/src ros2 pkg create --build-type ament_python camera_node 1. 2. 3. 4. 在新创建的包目录中,添加一个名为camera_publisher.py的Python脚本,内容如下: importrclpyfromrclpy.nodeimportNod...
ROS2部分读取对应的文件夹,并将对应的文件publish出来,并通过ros2 bag record的方式录制。 importcv2importrclpyfrom rclpy.nodeimportNodefrom sensor_msgs.msgimportImagefrom cv_bridgeimportCvBridgefrom cv_bridgeimportCvBridge,CvBridgeErrorclassImage_Publisher(Nod...

您也可以使用const&和std::shared_ptr来发布和订阅,但在这种情况下不会发生零拷贝。参考,https://github.com/ros2/demos/blob/iron/intra_process_demo/src/two_node_pipeline/two_node_pipeline.cpp ,和https://github.com/ros2/demos/blob/iron/intra_process_demo/include/image_pipeline/camera_node.hpp...
colcon build --packages-select camera_calibration depth_image_proc image_proc image_publisher image_rotate image_view stereo_image_proc 构建好这些软件包后再运行colcon build --symlink-install --packages-select image_pipeline命令就可以成功构建该软件包了。
node = ros2node("/node_1"); pub = ros2publisher(node,"/example_topic","example_b_msgs/Standalone"); Create a subscriber on the same topic. sub = ros2subscriber(node,"/example_topic"); Create a message and send the message.
