2021-02-17 16:20:40 -0500 | marked best answer | Turtlebot Gmapping with RPLIDAR encounters errors Hi, i know there were serveral questions about this error, but they are all about the kinect connected to the turtlebot.. I have a RPLIDAR A1 connected to the turtlebot and want to run gmapping slam algorithm. I dont have a kinect connected or any other sensors. I have Ubuntu 14.04 and ROS Indigo installed on a Intel NUC build on the turtlebot. I started this 3 commands in different terminals and a teleop command to start the Lidar scan, gmapping and RVIZ It works fine, i can see the map being built in RVIZ but i get this errors in the gmapping terminal: Has anyone an idea? Any help would be appreciated! |
2018-06-15 16:57:11 -0500 | marked best answer | Using RTABMAP with Gmapping? Hi there! I am building a map with a Kinect 360, a RPLidar-laserscanner and a turtlebot using RTABMAP on Ubuntu 14.04 and ROS Indigo. Hi, While using RTABMAP I get poor results for the registered 3D Point Cloud and the 2D grid_map (which I am using for navigation). There a many registration errors in both map. So I decided to use gmapping for building the 2D map and run rtabmap in parallel. I set "publish_tf" to false and got really good results for the 2D Map, but still poor results in the 3D point cloud. Is it possible in RTABMAP to prior the laserscanner data for RTABMAPs scan-matching and pose estimation? Or to use gmappings pose estimation for RTABMAPs point cloud registration? Or does anyone now another package to register the point clouds from kinect? I am using this launch file from now: (more) |

2017-01-12 06:34:52 -0500 | commented answer | RTABMAP How to save registered 3D point cloud? Hi matlabbe, sorry for bothering you again! But with cloud_map I only get the 2D projection of the registered 3D Map to the ground. Is it possible to save the registered 3D Point Cloud from the /rtabmap/mapData Topic to .pcd / .ply directly from the command line without using RTABMAPVIZ ? |

2016-12-21 04:32:32 -0500 | asked a question | RTABMAP How to save registered 3D point cloud? Hi, I am building a map with a Kinect 360 and a turtlebot using RTABMAP on Ubuntu 14.04 and ROS Indigo. Everything works fine, I can see the registered 3D point cloud on RTABMAPVIZ or with RVIZ. Now I want to save the 3D Point cloud to .pcd or .ply . I know there is the option in RTABMAPVIZ with File->Export 3D Cloud descripted here, but is there any option to do this without using RTABMAPVIZ? Is there any service I can call from the command line or from another node? Or to do this in RVIZ? Any help would be appreciated! |
