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. When trying to visualize the point clouds, be sure to change the Fixed Frame under Global Options to "laser_data_frame" as this is the default parent frame of the point cloud headers. tfframe id, : The OSRF was immediately awarded a // first compute the centroid of the data: //Eigen::Vector3f centroid; // make this member var, centroid_, // see http://eigen.tuxfamily.org/dox/AsciiQuickReference.txt. Build the Package. When trying to visualize the point clouds, be sure to change the Fixed Frame under Global Options to "laser_data_frame" as this is the default parent frame of the point cloud headers. If your system does not have a map_frame, just remove it, and make sure "world_frame" is set to the value of odom_frame.
