  • Is it possible to use both depth_image_to_laserscan and pointcloud_to . . .
    With pointcloud i would suggest trying rtabmap This however asumes that you are using a single realsense or kinect like rgb-d camera to generate the pointcloud As this devices only generate a view degrees wide laserscan its likely that a pure 360° laserscan algorythm might fail underperform
  • Pointcloud to laserscan launch file - ROS Answers archive
    Pointcloud to laserscan launch file I have a rgb-d camera and I want to convert the pointcloud to laserscan, in order to create a 2d map with google cartographer When I launch cartographer with the pointcloud to laser I get warnings and it is not working
  • Costmap_2d does not subscribe to LaserScan or PointCloud topic
    Thus, after having processed the raw pointcloud with some custom nodes, I can obtain a point cloud from the ground (topic: filteredpointsnoground) and a laser scan topic (topic: laserscan) Both of the topic are published wrt to the velodyne tf that is connected to odom by declaring this command "rosrun tf static transform publisher 0 0 0 0 0
  • pointcloud to laserscan slow - ROS Answers archive
    If you're building pointcloud_to_laserscan from sources, be sure to enable optimisations (-DCMAKE_BUILD_TYPE=Release) If not: get a platform with some more processing power? Pi's are quite limited, and if you're not using nodelets, the pointcloud gets copied quite a nr of times
  • how to get 3D pointcloud from 2D Laserscan without robot simulation
    All I have is a 2D Laser Scanner and a PC I am able to get the 2D live data of the scanner in RVIZ I want to make 3D representation by moving scanner I have used laser_assembler library to make PointCloud of LaserScans Now, i am getting the PointCloud in a single plane I have searched and found that we need to transform scans before
  • pointcloud_to_laserscan spatial offset - ROS Answers archive
    I'm using pointcloudtolaserscan to convert a pointcloud to laserscan, however, the result is spatially offset when comparing with the input cloud Anyone else experienced this or has any idea on what could be causing this? Yellow is input cloud, blue is output scan
  • Gmapping using data from Pointcloud to laserscan gives error . . .
    Try gmapping again after updating your time and date settings in both robot's pc and the remote pc If still, you're not getting transform from odom to base_link you can create a tf broadcaster from odom to base_link as in ros wiki tutorials or else you can use *cartographer_ros * to get transform from odom to base_link
  • Nav2 robot setup, local costmap not showing on Rviz
    The laserscan merger sends a pointcloud to the pointcloudtolaserscan node (humble branch) The resulting lidar seem to work correctly with other nodes, the output shows on Rviz, and the Global costmap is working correctly, aside from not showing any gradient to the inflation layer
  • Problem with ydlidar and conversion LaserScan - gt; PointCloud
    So i have the ydlidar F4 pro at the moment, i managed to visualize with rviz the laserScan topic etc it works fine Now i want to have (x,y,z) points so that my future robot will be able to move past objects and for this I would like to have points
