Parameter provide_odom_frame = true means that Cartographer will publish transforms between published_frame and map_frame. https://blog.teratail.com/entry/ai-terms Open an RViz session and subscribe to the points, images, and IMU topics in the laser frame. Next, expand the topic so that you see the "data" row. The node publishes the TF tree: map->odom->odom_source->range_sensor (in case you are using the odometry). Actual error: Fixed Frame [map] does not exist cv::IMREAD_GRAYSCALErviz c++: internal compiler error: (program cc1plus) [Bug]No tf data. resolution (float, default: 0.05) Resolution in meter for the map when starting with an empty map. render_panel_->initialize(manager_->getSceneManager(),manager_); rviz . In this tutorial, I will show you how to build a map using LIDAR, ROS 1 (Melodic), Hector SLAM, and NVIDIA Jetson Nano.We will go through the entire process, step-by-step. Set the initial pose of the robot by clicking the 2D Pose Estimate on top of the rviz2 screen (Note: we could have also set the set_initial_pose and initial_pose parameters in the nav2_params.yaml file to True in order to automatically set an initial pose.). Type: colcon_cd basic_mobile_robot cd rviz gedit urdf_config.rviz. After launching display.launch, you should end up with RViz showing you the following: Things to note: The fixed frame is the transform frame where the center of the grid is located. //a function to populate a pointCloud and a colored pointCloud; // provide pointers to these, and this function will fill them with data, // make an ellipse extruded along the z-axis. # 1a. 1.https://adamshan.blog.csdn.net/article/details/82901295-, //a function to populate two point clouds with computed points, // modified from: from: http://docs.ros.org/hydro/api/pcl/html/pcl__visualizer__demo_8cpp_source.html, //ROS message type to publish a pointCloud, //use these to convert between PCL and ROS datatypes. a random bucket of points, //height=1 implies this is not an "ordered" point cloud, //example of creating a point cloud and publishing it for rviz display, //this function is defined in: make_clouds.cpp, // create some point-cloud objects to hold data, "Generating example point-cloud ellipse.\n\n", "view in rviz; choose: topic= ellipse; and fixed frame= camera", // -----use fnc to create example point clouds: basic and colored-----, // we now have "interesting" point clouds in basic_cloud_ptr and point_cloud_clr_ptr, //here is the ROS-compatible pointCloud message. qq_45046735: No tf data. # 2. $ roslaunch mbot_description arbotix_mbot_with_camera_xacro.launch base_footprintbase_link0 0 0.1 0 0 0zbase_linkbase_footprintbase_linkzhttps://blog.csdn.net/abcwoabcwo/article/details/101108477 The target frame is the reference frame for the camera view.

Lets add a configuration file that will initialize RViz with the proper settings so we can view the robot as soon as RViz launches.
